RESUMO
BACKGROUND: Polycystic ovarian syndrome is a common endocrine disorder of reproductive age women. Many controlled ovarian stimulation (COS) strategies have been offered for the treatment of patients with PCOS undergoing in vitro fertilization, but the optimal protocol is still a controversy. There is no compelling evidence for the advantage of one stimulation protocol over the other. MATERIALS AND METHODS: This is a single-center prospective controlled study comparing long agonist and antagonist protocol in PCOS women. RESULTS: There was no significant difference in live birth rate and clinical pregnancy rate. Rate of ovarian hyperstimulation syndrome was significantly higher in the agonist group. Number of oocytes retrieved, number of follicles and peak estradiol levels were significantly more in the agonist group. CONCLUSION: The GnRH antagonist protocol is an equally effective but safer protocol in PCOS patients compared with the long agonist protocol.
RESUMO
BACKGROUND: Management of repeated implantation failure despite transfer of good-quality embryos still remains a dilemma for ART specialists. Scrapping of endometrium in the nontransfer cycle has been shown to improve the pregnancy rate in the subsequent IVF/ET cycle in recent studies. AIM: The objective of this randomized controlled trial (RCT) was to determine whether endometrial injury caused by Pipelle sampling in the nontransfer cycle could improve the probability of pregnancy in the subsequent IVF cycle in patients who had previous failed IVF outcome. SETTING: Tertiary assisted conception center. DESIGN: Randomized controlled study. MATERIALS AND METHODS: 100 eligible patients with previous failed IVF despite transfer of good-quality embryos were randomly allocated to the intervention group and control groups. In the intervention group, Pipelle endometrial sampling was done twice: One in the follicular phase and again in the luteal phase in the cycle preceding the embryo transfer cycle. OUTCOME MEASURE: The primary outcome measure was live birth rate. The secondary outcome measures were implantation and clinical pregnancy rates. RESULTS: The live birth rate was significantly higher in the intervention group compared to control group (22.4% and 9.8% P = 0.04). The clinical pregnancy rate in the intervention group was 32.7%, while that in the control group was 13.7%, which was also statistically significant (P = 0.01). The implantation rate was significantly higher in the intervention group as compared to controls (13.07% vs 7.1% P = 0.04). CONCLUSIONS: Endometrial injury in nontransfer cycle improves the live birth rate, clinical pregnancy and implantation rates in the subsequent IVF-ET cycle in patients with previous unsuccessful IVF cycles.
RESUMO
BACKGROUND: Estradiol levels fall rapidly in the luteal phase of ART cycles. So far, the effect of this estradiol decline on pregnancy outcome has remained controversial. AIM: To study the effect of early and midluteal estradiol decline on pregnancy and miscarriage rate. We also sought to determine whether estradiol fall was related to increased risk of bleeding per vagina in the first trimester among pregnancies which crossed 12 weeks. SETTING: Tertiary Assisted conception center. DESIGN: Retrospective study. MATERIALS AND METHODS: We analyzed data of 360 consecutive patients who underwent IVF-ET/ICSI cycles using one of the three protocols: Midluteal downregulation, short flare, and antagonist protocol. STATISTICAL METHODS: Statistical evaluation was performed with the Student's t test, Chi square, Fischer's exact test, analysis of variance, and Mann-Whitney tests were appropriate using SPSS for Windows, Standard version 11.0. RESULTS: The mean % EL-E2 and % ML-E2 declines were not significantly different in the pregnant and nonpregnant groups when analyzed separately in the three protocols. Also, the degree of midluteal estradiol decline did not correlate with pregnancy outcome. Moreover, the mean % early and midluteal estradiol decline did not differ significantly in patients with preclinical, clinical abortions, and ongoing pregnancy. The estradiol decline was not found to influence the risk of bleeding in the first trimester. CONCLUSIONS: Our results show that the degree of estradiol fall in the luteal phase of ART cycles does not influence pregnancy and first trimester miscarriage rate.
RESUMO
Pseudomyxoma peritonei is a rare, chronic relapsing disease with a guarded prognosis. Here, we describe such a case of a young patient presenting with primary infertility, who conceived following in-vitro fertilization with donor egg and had a successful pregnancy outcome. Literature regarding fertility and pregnancy outcome in this condition is reviewed.
