OBJECTIVE: To evaluate the pregnancy rate and time to pregnancy after timed coitus with or without superovulation in infertile young women younger than 35 years old with low serum anti-Müllerian hormone (AMH) levels (<25th percentile). MET…

OBJECTIVE: The aim of this study was to evaluate pregnancy outcomes and the live birth rate at 1-year age increments in women aged ≥40 years undergoing fresh non-donor in vitro fertilization (IVF) and embryo transfer (ET), and to identify p…

OBJECTIVE: To determine the preferred regimen for women with adenomyosis undergoing in vitro fertilization (IVF), we compared the IVF outcomes of fresh embryo transfer (ET) cycles with or without gonadotropin-releasing hormone (GnRH) agonis…

OBJECTIVE: To assess whether an early GnRH antagonist start leads to better follicular synchronization and an improved clinical pregnancy rate (CPR). METHODS: A retrospective cohort study. A total of 218 infertile women who underwent IVF b…

To evaluate the difference of serumanti-Mllerian hormone (AMH) levels in women between undergoing previous ovarian surgery with endometriosis and controls.

OBJECTIVE: To determine whether the serum β-human chorionic gonadotropin (hCG) profile following preimplantation genetic diagnosis (PGD) is lower than that of intracytoplasmic sperm injection (ICSI) cycles. METHODS: A total of 129 PGD cycl…

OBJECTIVE: To determine whether characteristics of sperm motility obtained by computer-assisted sperm analysis (CASA) could predict pregnancy after intrauterine insemination (IUI) in couples with unexplained infertility. METHODS: Three hun…

OBJECTIVE: To evaluate the ability of serum anti-Müllerian hormone (AMH), FSH, and age to clinically predict ovarian response to controlled ovarian hyperstimulation (COH) in IVF patients with endometriosis. METHODS: We evaluated 91 COH cyc…
