ObjectiveTo investigate prevalence of antiphospholipid antibody (APA) in Korean infertile women undergoing the first in vitro fertilization (IVF) treatment and to evaluate the influence of APA on the subsequent IVF outcomes.MethodTwo hundred nineteen infertile women who destined the first IVF were prospectively enrolled in 2 infertility centers. Male factor or uterine factor infertility and women with past or current endocrine or immunologic disorders were completely excluded. Plasma concentration of lupus anticoagulant was measured by clot-based method, and anticardiolipin antibody (IgG/IgM), and anti-β2-glycoprotein 1 antibody (IgG/IgM) was measured by enzyme-linked immunosorbent assay method before starting ovarian stimulation for IVF.ResultsAPA was positive in 13 women (5.9%). Lupus anticoagulant was positive in 2 women (0.9%), anticardiolipin antibody was positive in 7 women (3.2%), and anti-β2-glycoprotein 1 antibody was positive in 4 women (1.8%). In 193 women entering embryo transfer, clinical characteristics and stimulation outcomes were comparable between APA-positive (n=12) and APA-negative group (n=181). The clinical pregnancy rate (66.7% vs. 45.9%), ongoing pregnancy rate (58.3% vs. 37.0%), and miscarriage rate (12.5% vs. 19.3%) were all similar between APA-positive and APA-negative group.ConclusionThe prevalence of APA is low in Korean infertile women undergoing the first IVF cycle, and the presence of APA appears to neither decrease their first IVF success nor increase abortion rate.

ObjectiveOvarian reserve tests are commonly used to predict ovarian response in infertile patients undergoing ovarian stimulation. Although serum markers such as basal follicle-stimulating hormone (FSH) or random anti-Müllerian hormone (AMH) level and ultrasonographic markers (antral follicle count, AFC) are good predictors, no single test has proven to be the best predictor. In this study, we developed appropriate equations and novel nomograms to predict the number of oocytes that will be retrieved using patients' age, serum levels of basal FSH and AMH, and AFC.MethodsWe analyzed a database containing clinical and laboratory information of 141 stimulated in vitro fertilization (IVF) cycles performed at a university-based hospital between September 2009 and December 2013. We used generalized linear models for prediction of the number of oocytes.ResultsAge, basal serum FSH level, serum AMH level, and AFC were significantly related to the number of oocytes retrieved according to the univariate and multivariate analyses. The equations that predicted the number of oocytes retrieved (log scale) were as follows: model (1) 3.21–0.036×(age)+0.089×(AMH), model (2) 3.422–0.03×(age)–0.049×(FSH)+0.08×(AMH), model (3) 2.32–0.017×(age)+0.039×(AMH)+0. 03×(AFC), model (4) 2.584–0.015×(age)–0.035×(FSH)+0.038×(AMH)+0.026×(AFC). model 4 showed the best performance. On the basis of these variables, we developed nomograms to predict the number of oocytes that can be retrieved.ConclusionOur nomograms helped predict the number of oocytes retrieved in stimulated IVF cycles.

Cantrell's Pentalogy is a rare condition that consists of defects involving the abdominal wall, lower sternum, anterior diaphragm, pericardium, and heart. In the literature to date, pregnant women with Cantrell's Pentalogy have not been discussed. We performed successful vaginal delivery of a 23-yr-old nulliparous, primigravid woman who had been diagnosed with this condition. Diagnosis was based on cardiac catheterization, angiography, and echocardiogram, and abdominopelvic CT. Vaginal delivery may be an option for women with Cantrell's Pentalogy and may be attempted with caution.

To evaluate the safety and effectiveness of recombinant human follicle-stimulating hormone (rhFSH [Follitrope™]) in infertile women undergoing in vitro fertilization (IVF). To identify predictors of ovarian response that induce optimal clinical outcomes. This multicenter prospective study enrolled infertile women who were scheduled to undergo IVF after ovarian stimulation with rhFSH (Follitrope™) following the gonadotropin-releasing hormone (GnRH) agonist or GnRH antagonist protocol. Predictive factors for ovarian response were identified in the GnRH antagonist group based on the number of oocytes retrieved. A total of 516 infertile women were enrolled, among whom 136 (except one who withdrew before administration) received rhFSH using the GnRH agonist protocol and 379 using the antagonist protocol. The mean number of oocytes retrieved was 13.4 in the GnRH agonist group and 13.6 in the GnRH antagonist group. The clinical pregnancy rates were 32.3% (30/93) and 39.9% (115/288) in the GnRH agonist and antagonist groups, respectively. The incidence of ovarian hyperstimulation syndrome was 1.8% and 3.4% in the GnRH agonist and antagonist groups, respectively. No other significant safety risks associated with rhFSH administration were identified. Body mass index, basal serum FSH and anti-Müllerian hormone levels, and antral follicle count were identified as predictors of ovarian response by multiple regression with backward elimination, and the final regression model accounted for 26.5% of the response variability. In real-world practice, rhFSH (Follitrope™) is safe and effective in inducing ovarian stimulation in infertile women. Patient characteristics identified as predictors can be considered to be highly related to optimal clinical outcomes.
