Using laparoscope to remove an ectopic intrauterine device in the anterior wall of urinary bladder:A case report

BACKGROUND An intrauterine device(IUD)is a contraceptive device placed in the uterine cavity and is a common contraceptive method for Chinese women.However,an IUD may cause complications due to placement time,intrauterine pressure and other factors.Ectopic IUDs are among the most serious complications.Ectopic IUDs are common in the myometrium and periuterine organs,and there are few reports of ectopic IUDs in the urinary bladder,especially in the anterior wall.CASE SUMMARY A 52-year-old woman was hospitalized due to a urinary bladder foreign body found via abdominal ultrasound and computed tomography(CT)examination.The patient had a 2-year history of recurrent abdominal distension and lower abdominal pain,accompanied by frequent urination,urgency,dysuria and other discomfort.Ultrasound examination revealed foreign bodies in the bladder cavity,with calculus on the surface of the foreign bodies.CT revealed a circular foreign body on the anterior wall of the urinary bladder,suggesting the possibility of an ectopic IUD.After laparoscopic exploration,an annular IUD was found in the anterior wall of urinary bladder,and an oval calculus with a diameter of approximately 2 cm was attached to the surface of the bladder cavity.The IUD and calculus were successfully and completely removed.The patient recovered well after surgery.CONCLUSION Abdominal ultrasound and CT are effective methods for detecting ectopic IUDs.The IUD is located in the urinary bladder and requires early surgical treatment.The choice of surgical method is determined by comprehensively considering the depth of the IUD in the bladder muscle layer,the situation of complicated calculus,the situation of intravesical inflammation and medical technology and equipment.

Postpartum Intrauterine Device: Use and Follow-Up of Users in the Maternity Ward of the Ratoma Communal Medical Center in Conakry, Guinea

Objective: The aim of this study was to describe the use of the postpartum intrauterine device in the maternity ward of the Ratoma communal medical center in Conakry. Methods: This was a descriptive cross-sectional study carried out between July 1st 2015 and June 30 2016, i.e. a duration of one year. Results: A total of 551 patients received advice on various contraceptive methods. Most of this advice was given in the post-partum period (40.2%) and during antenatal care (39.1%). Of the patients advised, 87 (15.8%) used the intrauterine device. The majority of users (93%) were married and uneducated (63.2%), and 39.1% were poor. The majority (56.3%) of intra-uterine devices were inserted in the immediate post-partum period. The majority of women had no adverse events either during the first six weeks (n = 57;65.5%) or at 3rd months (n = 75;86.2%) or 6th months (n = 76;87.4%) after IUD insertion. Most users remained complication-free throughout the follow-up period (n = 76;87.4% at 6th weeks and 3rd months, and n = 77;88.5% at 6th months). The continuation rate was 89.7% at 6 weeks and 3rd months, and 87.4% at 6th months after insertion. The majority of users (87.0%) were satisfied with the care they received. Conclusion: This study showed very few complications among intrauterine device users, and high continuation and satisfaction rates. The intrauterine device is a long-acting, effective, reversible and safe contraceptive that can be used by most women for birth spacing in Guinea, where women do not regularly visit health facilities.

User Perspective of Misplaced PPIUCD and Factors Resulting in PPIUCD Removal: Qualitative Pilot Study

Objective: The aim of the current study was to assess the impact of operative interventions for misplaced device among women who opted for PPIIUCD and the evaluation of reasons for PPIUCD removal within the follow up period of two years. Design: A descriptive exploratory study was conducted over three months among fourteen PPIUCD acceptors at a tertiary care health facility in Delhi, India. Face-to-face & telephonic in-depth interviews were conducted with a selected sample of PPIUCD acceptors who had later opted for its removal. Results: Participants (n = 14) aged 24 – 40 exhibited generally positive attitudes towards PPIUCDs indicating an indicate an understanding of the importance of PPIUCD in preventing unintended pregnancies. Menstrual disturbance and misplaced IUCD were major reasons for removal. despite their own experience necessitating the removal of IUCD, positive experience by other family members (mothers in law) in this study helped to keep the confidence on the contraceptive. Themes included (a) general experience of PPIUCD use (b) Health Facility accessed for removal of IUCD (c) Would she recommend it to others? (d) preferred contraceptive after removal of IUCD. Conclusion: Misplaced IUCD, missing thread, menstrual irregularities, and pain are all associated with PPIUCD and are important reasons for dissatisfaction. Appropriate, timely and supportive individualized care that address knowledge gaps, societal perceptions, and healthcare system challenges would certainly help in reducing dissatisfaction due to PPIUCD and thereby the removal rates.

Giant exophytic cystic adenomyosis with a levonorgestrel containing intrauterine device out of the uterine cavity after uterine myomectomy: A case report

BACKGROUND A cystic lesion arising from the myometrium of the uterus, termed as cystic adenomyosis, has chocolate-like, thick viscous contents and contains various amounts of endometrial stroma below the glandular epithelium. It is an extremely rare type of adenomyosis.CASE SUMMARY Herein, we report an unusual case of a giant cystic mass in the pelvic cavity after uterine myomectomy. The patient complained of abnormal uterine bleeding and severe dysmenorrhea. After a levonorgestrel-containing intrauterine device(LNG-IUD) was inserted, her symptoms were greatly alleviated. However, the LNG-IUD was detected in the cystic cavity during the follow-up. For fear of the intrauterine device migrating into and damaging the surrounding viscera,surgical treatment was proposed. Therefore, laparoscopic resection of the lesion and removal of the LNG-IUD were performed and cystic adenomyosis with an LNG-IUD out of the uterine cavity was diagnosed.CONCLUSION We believe that myomectomy breaking through the endometrial cavity may have been a predisposing factor for the development of cystic adenomyosis in this case.

Releasing of Cupric Ion of Three types of Copper-bearing Intrauterine Contraceptive Device in Simulated UterineFluid

Objective To compare the cupric ion releasing in vitro o.f the three IUDs. Methods The stability o.f cupric ion releasing o.f IUDs including TCu 380.4 IUD （TCu 380A）, Multiload Cu375 IUD （MCu 375） and Yuangong 365 copper-bearing indomethacin-releasing IUD （Yuangong 365） by the determination of cupric ion releasing in simulated uterine fluid. The simulated uterine fluid was used for releasing media. Copper ion was determined by flame atomic absorption spectrometer. Results The cupric ion releasing of three IUDs were instable at the beginning and tend to be stable gradually. In the stable phase, the average level of cupric ion releasing of TCu380A, MCu375 and Yuangong 365 were 4.25±2.71-7.62±6.42 μg, 4.92±1.23 -8.62±3.08 μg and 2.19±0.40-4.68±1.66 μg, respectively. TCu380A had higher instable releasing level than those of Yuangong 365 （P〈0. 05）. Conclusion TCu 380.4 and MCu 375 showed a ＂burst release＂ during the first few days and the.former was of great significance（P〈0.05）. The initial cupric ion releasing of Yuangong 365 appeared to be the lowest, followed by MCu375 and TCu380A in a releasing order

Pre-Clinical Experimental Studies of Indomethacin-Releasing Copper Intrauterine Device

Effects of two types of intrauterine device (IUD) on the prostaglandins and endothelin (ET) in uterus and on the endometrial morphology in rats and rabbits, and Cu 2+ releasing amounts of both IUDs in vitro were observed. The results showed that the inhibiting action of the indomethacin releasing copper IUD (FICu IUD) on the PGI 2 was stronger than that on the TXA 2, the ratio of 6 keto PGF 1α /TXB 2 was reduced with the increase of the doses. There were significant differences between the groups. The FICu IUD could inhibit the rising of the ET level and lighten the endometrial impairment caused by the FCu IUD, and promote copper ion release. It was suggested that indomethacin released by FICu IUD could effectively reduce abnormal uterine bleeding.

Ectopic intrauterine device in the bladder causing cystolithiasis:A case report

BACKGROUND An intrauterine device(IUD)is a commonly used contraceptive among women in China.It is widely used because it is safe,effective,simple,economic,and reversible.Among the possible complications,an ectopic IUD in the bladder is rare.It occurs insidiously,has a long course,is associated with a high risk for injury,and is difficult to treat.CASE SUMMARY A 44-year-old woman was admitted for repeated episodes of urinary frequency,urgency,and dysuria over three months.Laboratory tests revealed significantly elevated urine leukocytes and bacteria.Urine culture suggested colonization with Enterococcus faecalis.Abdominal computed tomography images suggested an abnormally positioned IUD that was protruding into the bladder.Cystoscopy revealed a metallic foreign body with multiple stones on its surface in the left posterior bladder wall.The foreign body measured approximately 1 cm.Hysteroscopy revealed the arm of a V-type metal IUD embedded in the middle and upper sections of the anterior wall of the cervical canal.The majority of the IUD was located in the uterine cavity.Cystoscopy was performed,and a holmium laser was utilized to break the stones attached to the portion of the IUD in the bladder.The IUD was then removed through hysteroscopy.CONCLUSION Ectopic IUDs in the bladder can be diagnosed with thorough imaging and safely removed through cystoscopy or hysteroscopy.

Importance of abdominal X-ray to confirm the position of levonorgestrel-releasing intrauterine system:A case report

BACKGROUND Levonorgestrel-releasing intrauterine systems(LNG-IUSs)gradually release levonorgestrel into the uterus and is effective against hypermenorrhoea and dysmenorrhea.Complications associated with the insertion include expulsion,displacement,and uterine perforation.Ultrasonic identification of copper intrauterine devices(IUDs)is possible due to echogenicity from the copper coils.However,the barium sulfate coatings of LNG-IUSs do not always provide hyperechoic images.Both barium sulfate and copper are radiopaque and clearly identifiable on X-ray.Thus,X-ray imaging is required to locate LNG-IUSs.CASE SUMMARY A 46-year-old woman with hypermenorrhoea due to submucosal myomas was treated with LNG-IUS at another hospital.Three LNG-IUS insertions had apparently been followed by spontaneous expulsion,although objective confirmation using imaging was not performed.The patient was referred to our institution for surgery.At the first visit,there appeared to be no device in the uterus,and none was observed on transvaginal ultrasound.However,two LNGIUSs were observed in the pelvis on abdominal plain X-rays prior to surgery.Hysteroscopic myomectomy was performed,and the two LNG-IUSs were found to have perforated the myometrium.The devices were safely removed during surgery,and the submucosal myomas were also removed.The perforated section of the myometrium was minimal+ADs-therefore,a repair operation was not required.CONCLUSION Plain abdominal X-rays facilitate the determination of whether an LNG-IUS is in the uterine cavity.Therefore,it is important to confirm a device’s location,regardless of whether spontaneous expulsion is suspected,prior to inserting another device.

Intrauterine contraceptive device appendicitis: A case report

Uterine perforation is one of the serious complications associated with use of the intrauterine contraceptive device （IUD）. Uterine perforaUon by IUD can involve several neighboring organs. A case of acute appendicitis was caused by a Multiload Cu 375 TUD inserted previously. This is a rare complication and only fourteen previous cases were recorded in the literature.

Com parison betw een Two Techniques Used in Im m ediatePostplacentalInsertion of TCu 380AIntrauterine Device:36-Month follow-up

Three hundred and eighty four women in Shanghai who delivered vaginally and chose IUD for contraception received the copper T 380A IUD inserted vaginally within 10 min after delivery of the placenta(i.e.,immediate postplacental insertion, IPPI). Among them, 98.70% were primipara. The women were randomly divided into two groups: IUD inserted by hand and IUD insreted by ring forceps. Using Life Table Method and χ 2 test, expulsion and other discontinuation rates were compared at 6, 12, 24, and 36 months post insertion between these two different groups. No uterine perforation, infection or prolonged period of lochia occurred in the 384 cases. Expulsions were the main reason for discontinuation. From 6 months to 36 months, the gross cumulative rates of all discontinuation events (expulsion, pregnancy, removal for bleeding/pain, etc.) were not statistically significantly different (P>0.05). The results suggest that these two different insertion techniques do not significantly affect discontinuation rate in vaginal IPPI using the TCu 380 A, which appears to be suitable for postpartum insertion in Chinese women. Other relevant issues, such as breast feeding and IUD position in uterine cavity, are also analyzed and discussed in this paper.

Effect of Domestically-made Levonorgestrel-releasing Intrauterine Device on the Endocrine System and Mensentruation in Monkeys

Effect of domestically-made levonorgestrel-releasing intrauterine device (LNG, release rate: 6 μg/day) on the endocrine system and menstruation in mondeys was investigated. The results showed that the Estradiol (E2) and progesterone (P) levels were significantly decreased 2 ovulatory cycles after iusertion of the devices as compared with those before insertion in 3 monkeys (P>0. 001) ,suggesting an evident ovulation-suppressing effect. In 1 monkey, the E2 and P levels were the same before and after insertion,and expulsion of device was found in the monkey later. The plasma LNG concentration in 3 animals was 493. 69-454. 60 pg/ml and plasma LNG was not detected in 1 monkey. The hormone level returned to normal level after removal of the devices.

Postpartum intrauterine device contraception: A review

AIM： To review the safety （infection, perforation） and efficacy （expulsion, continuation rates, pregnancy） of intrauterine device （IUD） insertion in the postpartum period. METHODS： MEDLINE, PubMed and Google Scholar were searched for randomized controlled trials and prospective cohort studies of IUD insertions at different times during the postpartum period. Time of insertion during the postpartum period was documented speci-fically, immediate post placenta period （within 10 min）, early post placenta period （10 min to 72 h）, and de-layed/interval period （greater than 6 wk）. Other study variables included mode of delivery, vaginal vs cesarean, manual vs use of ring forceps to insert the IUD. RESULTS： IUD insertion in the immediate postpartum （within 10 min of placental delivery）, early postpartum （10 min up to 72 h） and Interval/Delayed （6 wk onward） were found to be safe and effcacious. Expulsion rates were found to be highest in the immediate postpartum groups ranging from 14% to 27%. Immediate post placental insertion found to have expulsion rates that ranged from 3.6% to 16.2%. Expulsion rate was significantly higher after insertion following vaginal vs cesarean delivery. The rates of infection, perforation and unplanned pregnancy following postpartum IUD insertion are low. Method of insertion such as with ring forceps, by hand, or another placement method unique to the type of IUD did not show any signifcant difference in expulsion rates. Uterine perforations are highest in the delayed/interval IUD insertion groups.Breastfeeding duration and infant development are not affected by delayed/interval insertion of the non-hormonal （copper） IUD or the Levonorgestrel IUD. Timing of the Levonorgestrel IUD insertion may affect breastfeeding. CONCLUSION： IUD insertion is safe and efficacious during the immediate postpartum, early postpartum and delayed postpartum periods. Expulsion rates are highest after vaginal delivery and when inserted during the immediate postpartum period. IUD associated infection rates were not increased by insertion during the postpartum period over interval insertion rates. There is no evidence that breastfeeding is negatively affected by postpartum insertion of copper or hormone-secreting IUD. Although perforation rates were higher when inserted after lactation was initiated. Randomized controlled trials are needed to further elucidate the consequence of lactation on postpartum insertion. Despite the concerns regarding expulsion, perforation and breastfeeding, current evidence indicates that a favorable risk beneft ratio in support of postpartum IUD insertion. This may be particularly relevant for women for whom barriers exist in achieving desired pregnancy spacing.

Opinions and Perceptions of Gynecologists and Midwives on the Use of the Intrauterine Device in Senegal

Objective: The purpose of this study was to analyze the opinions of gynecologists, midwives, and interns/Specialist students practicing in Senegal about the use of IUD, and to assess factors that stand as obstacles to IUD prescribing. Patients and methods: An online questionnaire was developed to assess providers’ IUD practices and attitudes. The questionnaire was based on the one used in a Swiss study on the same topic. The platform used was Google forms. The questionnaire was shared in associative platforms involving gynecologists, midwives and interns/Specialist students. Results and comments: We received 292 feedbacks. Gynecologists represented 13.7% of the sample, interns and specialist students 11.3% and midwives 76%. Parity is a determining factor in IUD selection. The care-providers were concerned about the followings, which might have prevented the use of IUD, even though it was indicated: infections (75.7%), pelvic pain (61.3%), expulsion (48.3%), increased risk of perforation (46.9%), women’s appreciation (45.2%), ectopic pregnancy (33.9%) and sexual behavior (28.4%). Conclusion: Our study reveals that providers’ apprehensions and concerns severely limit the availability of IUDs. These concerns are often unfounded, based on personal experiences and not on official recommendations. Parity is a major obstacle.

Effect of Mirena placement on reproductive hormone levels at different time intervals after artificial abortion

BACKGROUND Improper methods of contraception greatly increase the risk of abortion,cervical or endometrial lesions,and the number of recurrent artificial abortions.These complications result in the deterioration of a patient’s outcome.Further,the proportion of artificial abortions is highest among unmarried females.Placement of an intrauterine device,such as the Mirena,after an artificial abortion may decrease the likelihood of an endometrial injury caused by recurrent abortions while significantly improving its contraceptive effects.AIM To discuss the effect of Mirena placement on reproductive hormone levels at different time points after an artificial abortion.METHODS Women(n=119)undergoing an artificial abortion operation were divided into the study(n=56)and control(n=63)groups.In the study group,the Mirena was inserted immediately after the artificial abortion,whereas in the control group,it was inserted 4–7 d after the onset of the first menstrual cycle after abortion.All participants were followed-up for 6 mo to observe the continuation and expulsion rates and adverse reactions and to measure the levels of serum estradiol(E2),follicle stimulating hormone(FSH),and luteinizing hormone(LH).RESULTS The continuation rates were 94.64%and 93.65%in the study group and the control group,respectively.The expulsion rates were 1.79%and 3.17%in the study group and the control group,respectively.There was no statistically significant difference between the two groups(P>0.05).There were also no statistically significant differences in the proportion of patients with bacterial vaginitis,trichomonas vaginitis,or cervicitis between the groups(P>0.05).Six months after Mirena placement,E2 Levels were 45.50±7.13 pg/mL and 42.91±8.10 pg/mL,FSH 13.60±3.24 mIU/mL and 14.54±3.11 mIU/mL,and LH 15.11±2.08 mIU/mL and 14.60±3.55 mIU/mL in the study and control groups,respectively.There were no significant differences in hormone levels between the two groups(P>0.05).There were also no statistically significant differences in the proportions of abnormal menstruation,prolonged menstruation,or pain during intercourse between the study and control groups after Mirena placement(P>0.05).There were no statistically significant differences in uterine volume,sexual desire,sexual activity,or the sexual satisfaction score between the study and control groups before and after Mirena placement(P>0.05).CONCLUSION Placement of a Mirena intrauterine device immediately after an artificial abortion does not increase the risk of adverse reactions and can help prevent endometrial injury caused by recurrent abortions.

Effects of Copper-Containing Intrauterine Devices on the Endometrium

The use of copper-containing intrauterine devices(Cu-IUDs)is a safe,effective,and long-term contraceptive method.Here,we review the effects of Cu-IUDs on subsequent pregnancy and the morphology,local coagulation function,sensitivity to estrogen and progesterone,cell proliferation,and immune response of the endometrium.Studies on the morphology of endometrium indicate that the use of Cu-IUDs can affect the number and binding capacity of estrogen and progesterone receptors in the endometrium and reduce the response of the endometrium to estrogen and progesterone.The use of Cu-IUDs can also affect the proliferation of endometrial cells,suggesting that the aseptic inflammation caused by Cu-IUDs may differ from chronic infectious or noninfectious inflammation;this highlights that the use of Cu-IUDs provides protection against endometrial proliferative diseases.The use of Cu-IUDs increases local endometrial angiogenesis,bleeding tendency,and fibrinolytic activity,which can result in prolonged menstruation or abnormal uterine bleeding.Additionally,the use of Cu-IUDs can cause the infiltration of numerous lymphocytes,monocytes,macrophages,and other inflammatory cells around the endometrial gland and changes in endometrial immune function,immune cell function,and the number and type of immune molecules.Cu-IUD-induced decidual injury significantly increases the invasiveness of trophoblasts,further affecting the aberrant expression of their growth-,angiogenesis-,and invasion-related factors and improving the formation of the placenta.Moreover,the endometrial damage caused by Cu-IUD placement before embryo transfer can improve both clinical pregnancy and live birth rates;however,specific changes in the immune system after Cu-IUD use as well as its effects on future pregnancies require further investigation.

Successful live birth following hysteroscopic adhesiolysis under laparoscopic observation for Asherman’s syndrome: A case report

BACKGROUND Asherman’s syndrome is characterized by reduced menstrual volume and adhesions within the uterine cavity and cervix,resulting in inability to carry a pregnancy to term,placental malformation,or infertility.We present the case of a 40-year-old woman diagnosed with Asherman’s syndrome who successfully gave birth to a live full-term neonate after hysteroscopic adhesiolysis under laparoscopic observation,intrauterine device insertion,and Kaufmann therapy.CASE SUMMARY A 40-year-old woman(Gravida 3,Para 0)arrived at our hospital for specialist care to carry her pregnancy to term.She had previously undergone six sessions of dilation and curettage owing to a hydatidiform mole and persistent trophoblastic disease,followed by chemotherapy.She subsequently became pregnant twice,but both pregnancies resulted in spontaneous miscarriages during the first trimester.Her menstrual periods were very light and of short duration.Hysteroscopic adhesiolysis with concurrent laparoscopy was performed,and Asherman’s syndrome was diagnosed.The uterine adhesions covered the area from the internal cervical os to the uterine fundus.Postoperative Kaufmann therapy was administered,and endometrial regeneration was confirmed using hysteroscopy.She became pregnant 9 mo postoperatively and delivered through elective cesarean section at 37 wk of gestation.The postpartum course was uneventful,and she was discharged on postoperative day 7.CONCLUSION Hysteroscopic adhesiolysis with concurrent laparoscopy enables identification and resection of the affected area and safe and accurate surgery,without complications.

Cytotoxicity of six copper-bearing intrauterine devices on Chinese hamster ovary cells: the influence of frame, shape and copper surface area

Objective To evaluate the cytotoxicity of six commonly used copper-bearing intrauterine devices （Cu-IUDs） on Chinese hamster ovary （CHO-K1） cells and to investigate the influence of frame, shape and copper surface area of Cu-IUDs on cell toxicity.Methods Cu-IUDs were incubated in 10% FBS-DMEM/F12 culture medium at 37 ℃ for 24 h. The extracts were analyzed by flame atomic absorption spectrometer and were then diluted into different concentrations with culture medium. Finally, cytotoxicity of these original and diluted extracts on CHO-K1 cells was detected by cell counting kit-8 （CCK-8） assay.Results The viabilities of cells treated with the original extracts of six Cu-IUDs （TCu220C bulb, TCu220C, GCu220, GCu300, Yuangong Cu270 and Yuangong Ⅱ- 300） were all below 10% and the cupric ion concentrations in these extracts were 28.22 mg/L, 31.80 mg/L, 92.80 mg/L, 99.74 mg/L, 114.90 mg/L and 119.20 mg/L, respectively. After these original extracts were diluted, significant differences in cytotoxicity were exhibited. IUDs with larger copper surface areas （GCu300 and Yuangong Ⅱ-300） showed more cytotoxicity than those with smaller areas （GCu220 and Yuangong Cu270） respectively; When different shapes of Cu-IUDs were compared, TCu220C bulb showed lower cytotoxicity than TCu220C, and GCu300 exhibited higher toxicity than Yuangong Ⅱ-300; TCu220C displayed significantly lower cytotoxicity than GCu220 due to their differences in frames.Conclusion We presented evidence on the cytotoxic effects of copper ions released from Cu-IUDs on CHO-K1 cells and found that shape, frame together with copper surface area of Cu-IUDs had obvious influence on the cytotoxicity.

Vaginal Testosterone Propionate with Misoprostol Prior to Removal of Intrauterine Devices in Postmenopausal Women

Objective To explore and investigate a new treatment of releasing the risks and pain in removing intrauterine devices （IUD） from postmenopausal women. Methods Totally 240 postmenopausal women who needed to remove IUD were randomly divided into 3 groups. Group A （n =80） were preoperatively treated with 20 g/L vaginal testosterone propionate cod liver oil ointment （1 g/d） over a 2-week span of period, and vaginal misoprostol （200 μg） was one-time used at 2-3 h before operation. Group B （n =80） were treated with oral estradiol valerate （3 mg/d） from 7 d before operation. Other 80 women （group C） were treated with vaginal cod liver oil ointment （1 g/d） over a 2-week span of period before the operation day. The degree of cervical relaxation, operational difficulty, blood loss volume, the length of operation time and visual analogue scales （VAS） were evaluated, also the serum estradiol, testosterone and endometrial thickness were measured before and after medication. Results The degree of cervical relaxation, operational difficulty, blood loss, the length of operation time and VAS in group A were significantly better than those group C （P〈0.01）, whiles its blood loss volume was less than group B （P〈0.05） and there were no significant differences in serum estradiol, testosterone and endometrial thickness before and after medication. Conclusion Preoperative vaginal testosterone propionate combined with misoprostol would reduce the operational difficulties/risks and release the suffering of patients. The study may represent a safe and effective alternative to remove IUD in postmeno- pausal women.

A Comparative Study on the Contraception Efficacy and Safety of the Progesterone Releasing Contraceptive Vaginal Ring and the Copper T 380A IUD Inserted during the Lactation Period

A comparative study was made on the contraception efficacy and safety of the vaginal ring releasing 10mg/day Of progesterone in 160 cases and an intrauterine device,the cOPPer T 380A in 100 cases during lactation.It was found that the contraceptive method is acceptable from 42 to 60 days postpartum.No pregnancy occurred in the copper T 380A IUD users during lactation.Those methods are worth to be recommended because of their contraceptive efficacy and no adverse effects on breastfeeding children.Prenatal care and Family Planning Programe are administered together to raise lactation performance rate,and to decrease induced abortion rate,the health of mothers and children were protected.
