Male pseudo-hermaphroditism with persistent internal mullerian duct structures can present with a 46, XY karyotype with normal external genitalia and. It arises due to deficiency of antimullerian substance, resulting from reduced production/responsiveness to mullerian duct, leading to persistence of mullerian duct along with normal development of Wolffian duct structures. Presence of mullerian structure prevents testicular descent increasing the risk of testicular vanishing syndrome. The authors here report a case of 16 years old phenotypical male who came with retractile right sided testis and left side UDT in the urology outpatient department. Explorative laparotomy was performed and an ill-defined mass was excised and sent for histopathological examination. Histopathology revealed presence of mullerian structures. The serum testosterone level was normal, buccal smear cytology and karyotyping revealed a 46, XY genotype of the patient.展开更多

A total of 120 PCOS patients were enrolled and divided into three groups in terms of the ovarian response: a low-response group(n=36), a normal-response group(n=44), and a high-response group(n=40). The serum AMH and INHB levels were measured by enzyme-linked immunosorbent assay(ELISA). The follicle stimulating hormone(FSH), luteinizing hormone(LH), and estradiol(E2) levels were determined by chemiluminescence microparticle immunoassay. The correlation of the serum AMH and INHB levels with other indicators was analyzed. A receiver operating characteristic(ROC) curve was established to analyze the prediction of ovarian response by AMH and INHB. The results showed that there were significant differences in age, body mass index(BMI), FSH, total gonadotropin-releasing hormone(Gn RH), LH, E2, and antral follicle counts(AFCs) between the groups(P〈0.05). The serum AMH and INHB levels were increased significantly with the ovarian response of PCOS patients increasing(P〈0.05). The serum AMH and INHB levels were negatively correlated with the age, BMI, FSH level, Gn, and E2 levels(P〈0.05). They were positively correlated with the LH levels and AFCs(P〈0.05). ROC curve analysis of serum AMH and INHB in prediction of a low ovarian response showed that the area under the ROC curve(AUC) value of the serum AMH level was 0.817, with a cut-off value of 1.29 ng/m L. The sensitivity and specificity were 71.2% and 79.6%, respectively. The AUC value of serum INHB was 0.674, with a cut-off value of 38.65 ng/m L, and the sensitivity and specificity were 50.7% and 74.5%, respectively. ROC curve analysis showed when the serum AMH and INHB levels were used to predict a high ovarian response, the AUC value of the serum AMH level was 0.742, with a cut-off value of 2.84 ng/m L, and the sensitivity and specificity were 72.7% and 65.9%, respectively; the AUC value of the serum INHB level was 0.551 with a cut-off of 45.76 ng/m L, and the sensitivity and specificity were 76.3% and 40.2%, respectively. It was suggested the serum AMH and INHB levels have high clinical value in predicting the ovarian response of PCOS patients.展开更多

Before superovulation, 3 to 5 mm follicles presented on the ovaries of donor cows were counted, and blood was collected for measure of serum AMH. Across cows, serum AMH ranged from 0.013 to 0.898 ng/mL, with a mean of 0.293 ng/mL. The distribution of both AMH concentrations and follicle counts were divided into quartiles (AMH Q1 through Q4, with Q1 the lowest and Q4 the highest) for analysis. Donor cows in AMH Q4 had a greater (P < 0.001) number of 3 to 5 mm follicles at the start of superovulation than did donors in either Q1 or Q2. At embryo collection, cows in AMH Q3 and 4 had more (P < 0.001) palpable corpora lutea (CL) than cows in AMH Q1. The mean number of embryos recovered from donor cows in AMH Q4 was greater (P < 0.001) than those recovered from cows in either AMH Q1 or 2, but similar to that of AMH Q3. Analysis indicated that AMH was positively correlated (P < 0.001) with mean follicles (r = 0.458), CL (r = 0.452) and embryos recovered (r = 0.430). Donor cows with higher follicle counts (F Q3 and 4) at the start of superovulation had more (P < 0.001) palpable CL at embryo collection than donor cows in F Q1 or 2. More (P < 0.001) embryos were recovered from cows with the highest follicle counts (F Q4) as compared with cows having lower (F Q1 and 2) follicle counts. Results confirm that relative AMH concentration was positively correlated with number of small antral follicles in the ovaries of cows;both AMH measure and antral follicle counts might be used to predict subsequent superovulatory response in beef cows.展开更多

The expression of AMH is markedly different in males and females, both in concentration and temporality. In males, Sertoli cells maintain a high concentration of AMH in utero which peaks shortly after birth and then drops precipitously at puberty. In females, granulosa cells produce very low levels of AMH in utero followed by a transient spike in the neonatal period. Concentrations of the hormone then rise steadily through adolescence to a peak in the mid-twenties and subsequently decline until becoming undetectable in menopause. The study aimed to understand how Clinicians and Clinical Embryologists used anti-mullerian hormone (AMH) test to assess ovarian reserve, direct patient selection and treatment regimens and guide in vitro fertilization (IVF) cycle management in all registered fertility hospitals in a West African country, Ghana. A web-based survey (questionnaire) using google forms was performed to solicit responses from all IVF hospitals that are registered with the Fertility Society of Ghana (FERSOG). This questionnaire consisted of fifteen (15) broader questions, ten (10) of which assessed the clinics’ use of AMH. Responses were screened for quality to verify that only one (1) survey was completed by each IVF centre. The study was conducted during May and June 2020 at the In Vitro Fertilization (IVF) Department of the Airport Women’s Hospital (AWH) in Accra, Ghana. Results are reported as the proportion of IVF cycles represented by a particular answer choice. Survey responses were completed from 15 IVF centres, representing 2504 IVF cycles performed annually. A good majority (73.3%) [1835 IVF cycles] of the respondent IVF hospitals reported to use AMH as a first line test and 93.3% reported it as the best test for evaluating ovarian reserve. Another 66.7% reported that AMH results were extremely relevant to clinical practice. However, in contrast, for predicting live birth rate, 60% reported age as the best predictor in their practice. Overall, our results indicate that AMH is considered a first line test for assessing ovarian reserve and is relevant to the clinical practice of majority of Assisted Reproductive Technologies (ART) providers in Ghana.展开更多

These are typically lined by columnar epithelium and contain serous or mucinous f luid. If blood is found in the cyst, the source is usually due to the presence of endometrial elements in the cyst wall. The cyst is then termed an endometriotic cyst. In this case report, we have described a woman with a symptomatic 3 cm upper vaginal cyst who underwent surgical excision of the cyst. The cyst cavity was found to be full of old dark blood and mucous, however the wall contained no endometrial tissue and was lined by columnar epithelium which stained positive for mucous with mucicarmine. No cause for the intracystic hemorrhage was identif ied. We conclude that intracystic hemorrhage can occur in a simple Mullerian vaginal cyst in the absence of endometrial components.展开更多

But their molecular pathophysiology has been insufficiently studied. On the other hand, polycystic ovary syndrome (PCOS) is found in nearly 80% of women with hyperandrogenism and also in 8%-25% of normal ones. It seems that anti-mullerian hormone (AMH) which inhibits the formation of the mullerian ducts in male increases in women with PCOS. Therefore, the aim of the study is whether PCOS is associated with mullerian anomalies. Methods: In this case-control study, 83 women with PCOS and 83 cases without PCOS were evaluated with transvaginal ultrasound (TVS) for the diagnosis of mullerian anomalies. The results of each group were compared with other groups. Results: In the PCOS patients, TVS revealed mullerian anomalies in the uterine cavity in 29 out of 83 women. Among 29 patients who had lesions in their uterine cavity, 27 cases had septate uterus and two had arcuate uterus. In the healthy women, TVS revealed 6 septate uterus and 4 arcuate uterus abnormality cases of the uterine cavity. There were significant correlation between polycystic ovary syndrome of the patients and the mullerian anomalies lesions (i.e. septate and arcuate uterus) which were seen in them. Conclusion: Mullerian anomalies were more common in women with PCOS and the most common anomaly was uterine septum. In fact, the present results revealed that it seemed a cause-effect relationship between the mullerian anomalies and PCO syndrome may in fact exist.展开更多

Depending on the specific defect, a woman’s obstetric and gynecologic health may be adversely affected. In the present series patients presenting in the outpatient department with diagnosed Mullerian abnormalities were classified into several categories based on their presenting complaints. These patients were offered proper judicious management and were followed up as required. After one year of study period it was clear that most of these patients (barring a few exceptions) were treated optimally and they could live a healthy lifestyle thereafter.展开更多

In male embryos, the regression of the Mullerian duct is caused by the anti-Mullerian hormone (AMH), which plays an important role in the process of testicular descent. The physiological remnant of the Mullerian duct in males is the appendix testis (AT). In our previous study, we presented evidence for the decreased incidence of AT in cryptorchidism with intraoperative surgery. In this report, the expression of the anti-Mullerian hormone receptor type 2 (AMHR2), the specific receptor of AMH, on the AT was investigated in connection with different urological disorders, such as hernia inguinalis, torsion of AT, cysta epididymis, varicocele, hydrocele testis and various forms of undescended testis. The correlation between the age of the patients and the expression of the AMHR2 was also examined. Reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry were used to detect the receptor's mRNA and protein levels, respectively. We demonstrate that AMHR2 is expressed in the ATs. Additionally, the presence of this receptor was proven at the mRNA and protein levels. The expression pattern of the receptor correlated with neither the examined urological disorders nor the age of the patients; therefore, the function of the AT remains obscure.展开更多

It is second most common cause of primary amenorrhea after gonadal agenesis. The occurrence of mullerian agenesis in twins is very rare. We present the case of one of the non-identical twins, 22 years female, with primary amenorrhea. Her elder twin sister had a normal female reproductive system. In our case, diagnosis was supported by presence of definitive primary amenorrhea with well-developed secondary sexual characteristics. Normal physiological hormonal levels ruled out the ovarian or pituitary pathology. Imaging studies like ultrasonography and magnetic resonance imaging (MRI) provided additional confirmation.展开更多

This is based on its ability to reflect the number of growing follicles in the ovaries and knowing the level of AMH in a woman’s blood is generally a good indicator of her ovarian reserve and this can be achieved by making reference to a decision values. Objective: The purpose of this study was to measure the level of this hormone in normal, apparently healthy subjects in Rivers State, Nigeria with respect to age. The percentage of women, at their reproductive age with infertility problems in the state is in the increase and the essence was to establish a reference range for the hormone because of its clinical application in women fertility. Materials/method: A total of one thousand and sixty two apparently healthy women divided into four age groups were recruited for this study;this comprised of 300 each in age group of 20 - 30, 31 - 40, 41 - 50 respectively and 162 in 51 - 60 years age group from May 2014 to June 2017. They were randomly selected after filling a questionnaire form that has the information of age, tribe, last date of menses and whether on medication for any infertility problems. Excluded from the study were subjects identified with different endocrine dysfunction and/or on drugs for different types of anovulatory dysfunction. The Enzyme linked Immunoassay method was used in the measurement of the AMH. Results: The result from the measurement of plasma AMH levels showed a Mean ± SD value of 3.193 ± 0.943, 1.644 ± 0.691, 0.516 ± 0.276 and 0.135 ± 0.081 ng/ml respectively for the 1st, 2nd, 3rd and 4th age groups respectively. The mean value for the AMH decreases with increasing age and was statistically significant at the different age group levels (P −2.250 - 4.136;0.953 - 2.350;0.240 - 0.792 and 0.054 - 0.216 respectively for the age groups. This study summarizes the findings concerning AMH and its role as a marker for the quantitative aspect of ovarian reserve, ovarian aging, as well as ovarian dysfunction in this region of the country.展开更多

This study investigated possible correlations between serum AMH concentrations, mean number of lambs born (out-of-season in spring or fall), and estimated breeding values (EBVs) for number of lambs born (NLB), number of lambs weaned (NLW), maternal weaning weight (MWWT), weaning weight (WWT), and maternal index (determined by Sheep Genetics Australia). Blood was collected at breeding from Katahdin ewes between 0.7 and 7 years of age in 2015 (n = 163) for the analysis of serum concentrations of AMH. Anti-Mullerian hormone concentration was either expressed quantitatively or divided into quartiles (AMH Q1 through Q4, with Q1 the lowest and Q4 the highest, pg/ml). Data were analyzed by PROC CORR, GLM or chi-squared using SAS. Mean serum AMH was 182 ± 11 pg/ml and ranged from 0 to 1112 pg/ml. There was no correlation between serum AMH and EBVs for NLB, NLW, MWWT, WWT and the maternal index. Serum AMH concentration was similar in ewes in different age categories (P = 0.157). There was a correlation between EBV for NLB (0.29;P = 0.0002) and NLW (0.19;P = 0.013) with average number of lambs born. Ewes in the lowest AMH quartile (Q1) had a lower mean number of offspring born from spring breeding compared with ewes in other AMH quartiles (Q2, Q3, and Q4;P < 0.05). Further study is needed to determine the effectiveness of using serum AMH for selecting ewes for out-of-season (spring) breeding.展开更多

Generally, the follicle-stimulating hormone (FSH) level increases when the 17β-estradiol (E2) level decreases in menopause. However, the problem of these hormones should be determined by strict timing of sampling, and there are individual specificities of decreases of hormone levels. We considered that anti-Mullerian hormone (AMH) can be measured at any time of the menstrual cycle and that it shows ovary functional decline earlier than FSH/E2, and we examined whether AMH would possibly become a good index for climacteric disorders. The subjects were 163 healthy females and 21 patients with climacteric disorders between 20 and 59 years old. We examined AMH, FSH and E2 at the same time. It is understood that in healthy females, AMH decreases with age and a decline in ovary function occurs at a relatively early age. Patients visiting clinics for climacteric disorders often have normal-range serum FSH/E2 levels, and it is clear that these values could not serve as indices of menopause at these inspections. Upon measurement of AMH in patients with climacteric disorders, most showed less than normal range (< 14 pmol/L), suggesting a decline in ovarian function. In addition, AMH was low in females with climacteric disorders compared with those without them. In conclusion, AMH was suggested as an objective index for climacteric disorders and possibly as a new diagnostic marker.展开更多

文摘Background: Mullerian anomalies are relatively common and contributing to the problems of infertility and poor pregnancy outcomes. But their molecular pathophysiology has been insufficiently studied. On the other hand, polycystic ovary syndrome (PCOS) is found in nearly 80% of women with hyperandrogenism and also in 8%-25% of normal ones. It seems that anti-mullerian hormone (AMH) which inhibits the formation of the mullerian ducts in male increases in women with PCOS. Therefore, the aim of the study is whether PCOS is associated with mullerian anomalies. Methods: In this case-control study, 83 women with PCOS and 83 cases without PCOS were evaluated with transvaginal ultrasound (TVS) for the diagnosis of mullerian anomalies. The results of each group were compared with other groups. Results: In the PCOS patients, TVS revealed mullerian anomalies in the uterine cavity in 29 out of 83 women. Among 29 patients who had lesions in their uterine cavity, 27 cases had septate uterus and two had arcuate uterus. In the healthy women, TVS revealed 6 septate uterus and 4 arcuate uterus abnormality cases of the uterine cavity. There were significant correlation between polycystic ovary syndrome of the patients and the mullerian anomalies lesions (i.e. septate and arcuate uterus) which were seen in them. Conclusion: Mullerian anomalies were more common in women with PCOS and the most common anomaly was uterine septum. In fact, the present results revealed that it seemed a cause-effect relationship between the mullerian anomalies and PCO syndrome may in fact exist.
文摘Congenital anomalies of the female reproductive tract may involve the uterus, cervix, fallopian tubes, or vagina. Depending on the specific defect, a woman’s obstetric and gynecologic health may be adversely affected. In the present series patients presenting in the outpatient department with diagnosed Mullerian abnormalities were classified into several categories based on their presenting complaints. These patients were offered proper judicious management and were followed up as required. After one year of study period it was clear that most of these patients (barring a few exceptions) were treated optimally and they could live a healthy lifestyle thereafter.
文摘BACKGROUND Mixed malignant Mullerian tumours(MMMTs)are highly aggressive cancers that present at a late stage and are associated with a poor long-term prognosis.They are characterised by the presence of both epithelial and sarcomatous tissue types on histological examination and hence are known as biphasic tumours or carcinosarcomas.MMMTs almost always arise in the female genital tract(most commonly the uterus)but extragenital sites are also possible.Treatment options are limited and usually consists of surgery and adjuvant chemotherapy.CASE SUMMARY A 74-year-old woman presented with a 1-wk history of worsening left upper quadrant abdominal pain and a perisplenic mass on computed tomography(CT)scan.Features on imaging raised the possibility of a malignant process but were not diagnostic.Splenectomy was performed and histology confirmed the presence of a mixed malignant Mullerian tumour.A subsequent pelvic ultrasound identified another heterogenous cystic mass in the Pouch of Douglas without evidence of primary pathology in the uterus or adnexa.A second operation was performed for this with curative intent but previously-unknown widespread metastases were encountered at laparotomy.A biopsy of the pelvic mass confirmed it was also a MMMT with identical histological features to the perisplenic mass.There was no clinical or histological evidence of the MMMT having arisen primarily from the female genital tract.The patient subsequently suffered multi-organ failure and was palliated,succumbing to death on the 19th post-operative day.CONCLUSION Primary extragenital MMMT arising from the spleen or peritoneum represents an atypical form of an already rare gynaecological tumour.
文摘The female internal sex organs develop from the paramesonephric (Mullerian) duct. In male embryos, the regression of the Mullerian duct is caused by the anti-Mullerian hormone (AMH), which plays an important role in the process of testicular descent. The physiological remnant of the Mullerian duct in males is the appendix testis (AT). In our previous study, we presented evidence for the decreased incidence of AT in cryptorchidism with intraoperative surgery. In this report, the expression of the anti-Mullerian hormone receptor type 2 (AMHR2), the specific receptor of AMH, on the AT was investigated in connection with different urological disorders, such as hernia inguinalis, torsion of AT, cysta epididymis, varicocele, hydrocele testis and various forms of undescended testis. The correlation between the age of the patients and the expression of the AMHR2 was also examined. Reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry were used to detect the receptor's mRNA and protein levels, respectively. We demonstrate that AMHR2 is expressed in the ATs. Additionally, the presence of this receptor was proven at the mRNA and protein levels. The expression pattern of the receptor correlated with neither the examined urological disorders nor the age of the patients; therefore, the function of the AT remains obscure.
文摘Mullerin agenesis also referred as mullerian aplasia, Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKH) or vaginal agenesis is the congenital anomaly of vertical fusion defect of mullerian system resulting in variable abnormalities of female reproductive tract with normal functioning ovaries. It is second most common cause of primary amenorrhea after gonadal agenesis. The occurrence of mullerian agenesis in twins is very rare. We present the case of one of the non-identical twins, 22 years female, with primary amenorrhea. Her elder twin sister had a normal female reproductive system. In our case, diagnosis was supported by presence of definitive primary amenorrhea with well-developed secondary sexual characteristics. Normal physiological hormonal levels ruled out the ovarian or pituitary pathology. Imaging studies like ultrasonography and magnetic resonance imaging (MRI) provided additional confirmation.
文摘Background: The measurement of circulating anti-Mullerian hormone (AMH) in the plasma of adult women has been used as a tool in the assessment of ovarian reserve. This is based on its ability to reflect the number of growing follicles in the ovaries and knowing the level of AMH in a woman’s blood is generally a good indicator of her ovarian reserve and this can be achieved by making reference to a decision values. Objective: The purpose of this study was to measure the level of this hormone in normal, apparently healthy subjects in Rivers State, Nigeria with respect to age. The percentage of women, at their reproductive age with infertility problems in the state is in the increase and the essence was to establish a reference range for the hormone because of its clinical application in women fertility. Materials/method: A total of one thousand and sixty two apparently healthy women divided into four age groups were recruited for this study;this comprised of 300 each in age group of 20 - 30, 31 - 40, 41 - 50 respectively and 162 in 51 - 60 years age group from May 2014 to June 2017. They were randomly selected after filling a questionnaire form that has the information of age, tribe, last date of menses and whether on medication for any infertility problems. Excluded from the study were subjects identified with different endocrine dysfunction and/or on drugs for different types of anovulatory dysfunction. The Enzyme linked Immunoassay method was used in the measurement of the AMH. Results: The result from the measurement of plasma AMH levels showed a Mean ± SD value of 3.193 ± 0.943, 1.644 ± 0.691, 0.516 ± 0.276 and 0.135 ± 0.081 ng/ml respectively for the 1st, 2nd, 3rd and 4th age groups respectively. The mean value for the AMH decreases with increasing age and was statistically significant at the different age group levels (P −2.250 - 4.136;0.953 - 2.350;0.240 - 0.792 and 0.054 - 0.216 respectively for the age groups. This study summarizes the findings concerning AMH and its role as a marker for the quantitative aspect of ovarian reserve, ovarian aging, as well as ovarian dysfunction in this region of the country.
文摘Anti-Mullerian hormone (AMH) is an endocrine marker for fertility in many species. This study investigated possible correlations between serum AMH concentrations, mean number of lambs born (out-of-season in spring or fall), and estimated breeding values (EBVs) for number of lambs born (NLB), number of lambs weaned (NLW), maternal weaning weight (MWWT), weaning weight (WWT), and maternal index (determined by Sheep Genetics Australia). Blood was collected at breeding from Katahdin ewes between 0.7 and 7 years of age in 2015 (n = 163) for the analysis of serum concentrations of AMH. Anti-Mullerian hormone concentration was either expressed quantitatively or divided into quartiles (AMH Q1 through Q4, with Q1 the lowest and Q4 the highest, pg/ml). Data were analyzed by PROC CORR, GLM or chi-squared using SAS. Mean serum AMH was 182 ± 11 pg/ml and ranged from 0 to 1112 pg/ml. There was no correlation between serum AMH and EBVs for NLB, NLW, MWWT, WWT and the maternal index. Serum AMH concentration was similar in ewes in different age categories (P = 0.157). There was a correlation between EBV for NLB (0.29;P = 0.0002) and NLW (0.19;P = 0.013) with average number of lambs born. Ewes in the lowest AMH quartile (Q1) had a lower mean number of offspring born from spring breeding compared with ewes in other AMH quartiles (Q2, Q3, and Q4;P < 0.05). Further study is needed to determine the effectiveness of using serum AMH for selecting ewes for out-of-season (spring) breeding.
文摘The diagnosis of climacteric disorders in gynecology is performed on the basis of symptoms rather than hormonal levels. Generally, the follicle-stimulating hormone (FSH) level increases when the 17β-estradiol (E2) level decreases in menopause. However, the problem of these hormones should be determined by strict timing of sampling, and there are individual specificities of decreases of hormone levels. We considered that anti-Mullerian hormone (AMH) can be measured at any time of the menstrual cycle and that it shows ovary functional decline earlier than FSH/E2, and we examined whether AMH would possibly become a good index for climacteric disorders. The subjects were 163 healthy females and 21 patients with climacteric disorders between 20 and 59 years old. We examined AMH, FSH and E2 at the same time. It is understood that in healthy females, AMH decreases with age and a decline in ovary function occurs at a relatively early age. Patients visiting clinics for climacteric disorders often have normal-range serum FSH/E2 levels, and it is clear that these values could not serve as indices of menopause at these inspections. Upon measurement of AMH in patients with climacteric disorders, most showed less than normal range (< 14 pmol/L), suggesting a decline in ovarian function. In addition, AMH was low in females with climacteric disorders compared with those without them. In conclusion, AMH was suggested as an objective index for climacteric disorders and possibly as a new diagnostic marker.
文摘BACKGROUND Gynaecologists should be aware of a rare obstructive Mullerian duct abnormality like Robert’s uterus and perform further surgery when necessary.CASE SUMMARY We report a 41-year-old mother of two children with Robert’s uterus who was examined and treated by laparoscopy and hysteroscopy.Unlike the existing cases reported in the literature,this patient had a late onset of Robert’s uterus symptoms.Due to right tubal ectopic pregnancy 3 years previously,the patient was treated with right salpingectomy and left tubal ligation but suffered aggravated left lower abdominal pain.She was examined and treated by laparoscopy and hysteroscopy,and is completely asymptomatic at 5-year followup.CONCLUSION The typical obstructive Mullerian abnormality requires further surgery.Combined laparoscopy and hysteroscopy is an effective,minimally invasive technique with better recovery outcomes than traditional transabdominal procedures.
