Large-scale retrospective analysis of methodological factors affecting pregnancy rates after embryo transfer for in vitro fertilization.

This study aimed to investigate the impact of methodological factors on pregnancy rates after embryo transfer (ET) for in vitro fertilization. This retrospective cross-sectional study was conducted between September 2020 and April 2022. A total of 2048 patients who underwent ultrasonography-guided first frozen embryo transfer (FET) or a fresh ET cycle due to infertility were included in the study.

Euploidy rates of embryos in young patients with good and low prognosis according to the POSEIDON criteria.

Research Question: Does an association exist between ovarian reserve, ovarian response and embryonic euploidy in female patients under age 35 years?

Design: This was a retrospective analysis of intracytoplasmic sperm injection and preimplantation genetic testing for aneuploidies cycles among patients enrolled at Bahceci Fulya IVF Center between January 2016 and August 2019. A total of 133 patients in POSEIDON group 1 (suboptimal responder; female age <35 years, antral follicle count [AFC] ≥5, number of oocytes retrieved <10) (group A), 133 patients in POSEIDON group 3 (expected low responder; female age <35 years, AFC <5) (group B) and 323 in the non-low-prognosis group (female age <35 years, AFC ≥5 and number of oocytes retrieved >9) (group C) were included.

Results: There was no significant difference in euploidy rate per embryo among the three groups (61.

Prediction of gestational diabetes mellitus at first trimester in low-risk pregnancies.

Objective: We aimed to assess the relationship among the sex hormone-binding globulin (SHBG), homeostasis model assessment (HOMA), glycosylated hemoglobin (HbA1c), and cholesterol panel values to predict subsequent gestational diabetes mellitus (GDM) in low-risk pregnancies.

Materials And Methods: Thirty-eight pregnant women with GDM and 295 low-risk pregnant women without GDM were included in this study. Maternal blood samples were obtained during the first trimester examination to determine the SHBG, HbA1c, fasting blood glucose, insulin, thyroid stimulating hormone (TSH), free thyroxine, total cholesterol, triglycerides (TG), high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (LDL-C) levels.

Comparison of two doses of recombinant hcg for oocyte maturation in obese women (BMI > or = 30) undergoing assisted reproductive techniques.

Objective: To compare the efficacy of two doses (250 microg vs. 500 microg) of r-hCG for oocyte maturation in obese women with a body mass index (BMI) > or = 30 and undergoing assisted reproduction techniques.

Materials And Methods: A Prospective, randomized, clinical study of seventy two patients undergoing IVF/ intracytoplasmic sperm injection cycles with BMI > or = 30 kg/m2.

A prospective, randomized, controlled study to compare two doses of recombinant human chorionic gonadotropin in serum and follicular fluid in woman with high body mass index.

This prospective, randomized, controlled study compares the efficiency of 250 microg or 500 microg of recombinant hCG in serum and follicular fluid (FF) levels and pregnancy rates (PR) in women with high body mass index (BMI) (>or=26 kg/m(2)) undergoing assisted reproduction treatment (ART). Treatment outcomes are similar between the two groups.
