RESUMO
BACKGROUND: Female infertility is a crucial problem with significant implications for individuals and society. In this study, we explore risk factors for infertility in Korean women. METHODS: A total of 986 female patients who visited six major infertility clinics in Korea were recruited from April to December 2014. Fertile age-matched controls were selected from two nationwide survey study participants. Conditional logistic regression after age-matching was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) of each risk factor for infertility. RESULTS: Women with a body mass index (BMI) < 18.5 kg/m² had 1.35 times higher odds of infertility (OR, 1.35; 95% CI, 1.03-1.77), while those with a BMI ≥ 25.0 kg/m² had even higher odds (OR, 2.06; 95% CI, 1.61-2.64) compared to women with a normal BMI (18.5 kg/m² ≤ BMI < 25 kg/m²). Ever-smokers exhibited 4.94 times higher odds of infertility compared to never-smokers (95% CI, 3.45-8.85). Concerning alcohol consumption, women who consumed ≥ 7 glasses at a time showed 3.13 times significantly higher odds of infertility than those who consumed ≤ 4 glasses at a time (95% CI, 1.79-5.48). Lastly, women with thyroid disease demonstrated 1.44 times higher odds of infertility compared to women without thyroid disease (95% CI, 1.00-2.08). CONCLUSION: Female infertility in Korea was associated with underweight, obesity, smoking, alcohol consumption, and thyroid disease.

OBJECTIVE: This study aimed to investigate the impact of thyroid autoantibodies and serum TSH levels on clinical IVF outcomes. MATERIALS AND METHODS: This study included 260 Korean women scheduled for their first IVF between 2013 and 2017. Serum levels of thyroid hormone, TSH, and antibody for thyroid peroxidase and thyroglobulin were measured just before the first ovarian stimulation. Clinical pregnancy rate (PR), ongoing PR, and miscarriage rate were analyzed according to thyroid autoimmunity and serum TSH levels. The primary outcome was ongoing PR beyond 12 weeks of gestation. RESULTS: The ongoing PR and miscarriage rates were similar between women with positive (n = 29) and negative autoantibodies (n = 186). In women with subclinical hypothyroidism (serum TSH ≥4.2 µIU/mL), ongoing PR was significantly lower than euthyroid women (22.2%, vs. 44.7%, p = 0.045), but miscarriage rate was similar. The group with serum TSH ≥3.4 µIU/mL showed a significantly lower ongoing PR (23.9% vs. 46.7%, p = 0.005) and significantly higher miscarriage rate (38.9% vs. 14.1%, p = 0.020). In multivariate logistic regression analysis, serum TSH ≥3.4 µIU/mL was an independent unfavorable predictor for ongoing PR (odds ratio 0.375, p = 0.013). CONCLUSION: Thyroid autoantibodies did not affect clinical IVF outcomes, but women with serum TSH ≥3.4 µIU/mL demonstrated poor IVF outcomes.

OBJECTIVE: In this retrospective study, we analyzed factors influencing the ongoing pregnancy rate (PR) in women with repeated implantation failure (RIF) undergoing embryo transfer with endometrial receptivity array (ERA). METHODS: Eighty-three consecutive personalized embryo transfers (pETs) with ERA, from 54 women with RIF, were selected from June 2020 to April 2022. Vitrified blastocyst transfer was timed based on ERA results. RESULTS: The ongoing PR per pET was 33.7%. Using ERA, the endometrium was identified as pre-receptive in 26 cycles, early receptive in 25 cycles, receptive in 31 cycles, and late receptive in one cycle. With cycles categorized into three receptivity phases (pre-receptive, early receptive, or receptive), no significant differences were found in the clinical PR (27.3%, 55.6%, and 40%, respectively) or ongoing PR (9.1%, 55.6%, and 40%, respectively) after a single blastocyst transfer. Similarly, no significant differences were observed in the clinical PR or ongoing PR after the transfer of two or more blastocysts. Among women with ongoing pregnancy relative to those without, age at first pET was significantly lower (35 years vs. 39 years, p=0.001), while blastocyst score (23 vs. 18, p=0.012) and the proportion of blastocyst scores >18 (71.4% vs. 38.9%, p=0.005) were significantly higher. In multiple logistic regression analysis, the woman's age (odds ratio [OR], 0.814; 95% confidence interval [CI], 0.706 to 0.940; p=0.005) and blastocyst score >18 (OR, 3.052; 95% CI, 1.075 to 8.665; p=0.036) were identified as significant factors influencing ongoing pregnancy. CONCLUSION: In pET with ERA, ongoing pregnancy was closely associated with woman's age and blastocyst quality.
RESUMO
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.

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.

OBJECTIVE: To 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. METHOD: Two 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-ß2-glycoprotein 1 antibody (IgG/IgM) was measured by enzyme-linked immunosorbent assay method before starting ovarian stimulation for IVF. RESULTS: APA 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-ß2-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. CONCLUSION: The 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.
RESUMO
OBJECTIVE: Ovarian 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. METHODS: We 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. RESULTS: Age, 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. CONCLUSION: Our nomograms helped predict the number of oocytes retrieved in stimulated IVF cycles.
