The aim of this study was to evaluate the clinical efficacy of body mass index (BMI) as a predictor of in vitro fertilization and embryo transfer (IVF-ET) outcomes. Two hundred twenty-three IVF-ET cycles in 164 patients under 37 yr using GnRH agonist long protocols were included in this retrospective study. All of the selected cases were divided into two groups by a cutoff of 24 kg/m2 and these two groups were compared in regard to the outcomes of IVF-ET. There were no significant differences between group 1 (BMI <24 kg/m2) and group 2 (BMI > or = 24 kg/m2) in age, basal serum FSH level, estradiol (E2) level and endometrial thickness on hCG day, number of retrieved oocytes and transferred embryos. However, higher doses of gonadotropins were used in group 2 (30.8+/-12.7 ampoules vs. 35.4+/-15.3 ampoules, p=0.051). The clinical pregnancy rate was significantly lower in group 2 (25.9% vs. 10.5%, p=0.041) and implantation rate tended to be lower in group 2 (12.7% vs. 6.8%, p=0.085). BMI > or = 24 kg/m2 can be a candidate prognosticator of IVF-ET outcomes.

N/A Objective : The effects of superovulation on the expression of mRNA and protein of TIMP-3 and MMP-9 in murine endometrium were assessed.Methods : Using murine pregnant uteri of gestation day (g.d.) 4, 5 and 6 after injection of PMSG 5 and 10 IU, the effects of superovulation were assessed and compared with those of natural pregnancy and pseudopregnancy groups using quantitative competitive RT-PCR and immunohistochemical staining.Results : Expression of TIMP-3 mRNA and protein showed an increase in PMSG groups and pseudopregnancy group, while there was no difference in MMP-9 expression between natural pregnancy and PMSG, pseudopregnancy groups on g.d. 4 through g.d. 6. Conclusions : This study suggests that ovarian hyperstimulation by gonadotropin, which produces many oocytes and embryos, may have a detrimental effect on embryonic implantation and its relevant endometrial remodeling process by increase in expression of TIMP-3 in murine endometrium.

N/A Objectives : To assess the prevalence of autoantibodies in patients with endometriosis. Materials and Methods : The prevalence of autoantibodies were investigated in 93 patients with endometriosis diagnosed by laparoscopy or laparotomy. Autoantibodies, such as antithyroglobulin antibody, antimicrosomal antibody, antinuclear antibody (ANA), antiphospho -lipid antibody (APA), lupus anticoagulant (LAC), anti-dsDNA, and rheumatoid factor, were measured in sera of the subjects. The prevalence and distribution of autoantibodies were analyzed according to the stage of endometriosis. Results : All seven autoantibodies were checked in 73 patients out of 93 patients. Autoantibodies were identified in 23 of 73 patients with endometriosis (31.5%). Antibodies detected were antithyroglobulin antibody (15.2%), ANA (12.0%), antimicrosomal antibody (8.7%), anti-dsDNA (5.4%), and rheumatoid factor (4.4%), APA (2.2%) and LAC (1.3%). The prevalence of autoantibodies did not differ by the AFS stage. Conclusion : Autoantibodies were detected in about one-third of patients with endometriosis. The prevalence of autoantibodies did not differ by the stage.
