Methods The pregnancy outcomes of patients with advanced EMS (542 cycles), who were prepared for FET, were retrospectively assessed. Included patients underwent a total of 233 FET cycles (180 patients) using natural cycle (NC), a total of 142 FET cycles (115 patients) using letrozole (LE) ovulation induction, and a total of 167 FET cycles (137 patients) using hormonal replacement treatment (HRT) for endometrial preparation.Results There were no significant diffenences in the clinical pregnancy rate (LE: 49.30%, NC: 50.21%, and HRT: 43.11~/o, P=0.343), the implantation rate (LE: 29.26%, NC: 36.03%, and HRT: 29.55%, P=0.084), and the live birth rate (LE: 38.02%, NC: 39.11%, and HR T." 35.33 %, P=O. 648) among the three groups. No statistically signifi- cant differences were observed in the ongoing pregnancy rate, the miscarriage rate, and the pregnancy complication rate. The single birth weight in patients using NC- FET was lower than that in patients using HRT-FET (P=0.044) and a higher twin birth weight in patients using LE-FET were observed compared with other groups (P=O. 022). The rate of birth weight 〈2 500 g was also higher in the NC-FET group than in other groups. No congenital birth defects were found in the three groups. Conclusion Different endometrial preparation protocols without ultra-long GnRH-a down-regulation for FET yield similar pregnancy outcomes in patients with EMS. A tailored endometrial preparation protocol should be recommended according to different patients' situation.展开更多

Methods In the retrospective study, 842 patients undergoing IVF were collected and classified into two groups: hMG in combination with CC in mid-to-late follicular phase (group A, n=319) and short protocol of GnRHa-hMG (group B, n=523). The main outcome measures were ovarian responses in stimulation cycles and pregnancy outcomes in subsequent frozen-thawed embryo transfer (FET) cycles. Results In group A, the serum LH concentration on day 8 -10 was similar with that on the day of hCG administration (2.43 ± 1.92 IU vs 2.51 ±2.05 IU). The number of mature follicles and oocytes retrieved was significantly lower in group A than in group B while the fertilization rate and the cleavage rate were comparable. The clinical pregnancy rate (47. 79% vs 48.04%), the implantation rate (32.49% vs 33.11%) and the cumulative pregnancy rate (58.09% vs 60.22%) were respectively similar in group A and group B. Conclusion hMG in combination with CC in mid-to-late follicular phase results in the same pregnancy outcome as short protocol. The novel protocol may take the advantage of eliminating the occurrehce of a premature endogenous LH Surge.展开更多

Methods In the retrospective cohort study, 2 166patients undergoing IVF/ICSI with moderate or high response were recruited and classified into three groups according to the trigger dose of hCG: 2 000 IU (group A, n=722), 3 000 IU (group B, n=722) and 5 000 IU (group C, n= 722). The main outcome was the proportion of mature oocytes retrieved, fertilization rates, clinical pregnancy rates, cumulative pregnancy rates and incidence of ovarian hyperstimulation syndrome (OHSS). Results No evidence of statistically difference was found in the proportion of mature oocytes retrieved (89.92%, 91.40%, 90.20%, respectively) and fertilization rate (79.8%, 80.07%, 80.51%, respectively) among groups A, B and C. Serum E2 level on the day of hCG injection, the number of mature oocytes retrieved and good-quality embryos in group A were significantly higher than those in group B and group C. Clinical pregnancy rates per transfer cycle (45.95%, 43.97% and 44.25%), ongoing pregnancy rates (43.17%, 40.91% and 42,53%), implantation rates (30, 74%, 2Z 78% and 29.86%) and cumulative pregnancy rates per patient (58.31%, 53.6% and 54.85%)A reduced hCG dose of 2 000 IUfor moderate or high responders leads展开更多

Methods Two infertile patients with high ovarian response undergoing stimulation for IVF,, in which 800 IU of hCG was injected by mistake. IVF patients treated under a short protocol with 800 IU of hCG triggering ovulation. Live birth, clinical pregnancy outcomes and ovarian hyperstimulation syndrome (OHSS) were observed. Results Neither cycle of the two patients was canceled for oocyte retrieval failure and no OHSS was observed. Both patients gave birth to live twins after FET. Conclusion Triggering oocyte maturation in two hyper-responders by employing 800 IU of hCG could produce a good quantity of good-quality oocytes and an excellent clinical pregnancy and retain the opportunity for conception and live birth. Broader studies are needed.展开更多

Methods A total of 258 normal ovulatory IVF/ICSI patients undergoing ovarian stimulation in a Gn and MPA protocol were analyzed in this retrospective study and allocated into three groups according to the Gn used: group A, hMG-A (brand name: Fengyuan, n=105); group B, hMG-B (brand name: Lebaode, n=90); group C: u-FSH (brand name: Lishenbao, n=63). The hormone profile, embryological characteristics, and the pregnant results after frozen-thawed embryo transfer (FET) were compared among the three groups. Results There was no significant difference in the number of oocytes retrieved among the three groups (12.1± 6.9 vs 12.1±5.6 vs 13.1 ±8.8, P〉0.05). Other indicators such as the number of mature oocyte, fertilization, cleavage and viable embryo were similar (P〉0.05). No premature LH surges were detected, with a range of 0.04-7.38 IU/L. No differences were found in the clinical pregnancy rate per transfer (43.48% vs 37.93% vs 40. 74%, P〉0.05) and the implantation rate (34.88% vs 22.22% vs 26.42%, P〉O.05). Conclusion MPA is an effective oral alternative for the prevention of premature LH surges. Progestin-primed ovarian stimulation (PPOS) is a novel regimen of ovarian stimulation in combination with embryo cryopreservation, in which the two types of hMG are as effective as u-FSH.展开更多
