BACKGROUND: Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and a major cause of anovulatory infertility, often requiring assisted reproductive technology (ART). The freeze-all strategy followed by frozen-thawed embryo tr…
STUDY QUESTION: Is there an association between changes in endometrial thickness (EMT) following progesterone administration and pregnancy outcomes in frozen-thawed embryo transfers (FETs) at Day 3 (D3) and blastocyst stages? SUMMARY ANSWE…
RESEARCH QUESTION: Does surgical management of ovarian endometriomas improve in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)? DESIGN: This retrospective study analyzed 1,456 IVF/ICSI cycles from June 2017 to September …
BACKGROUND: Females with diminished ovarian reserve (DOR) have significantly lower cumulative live birth rates (CLBRs) than females with normal ovarian reserve. A subset of young infertile patients, whose ovarian reserve is declining but ha…
The development of novel therapeutic approaches to facilitate endometrial repair and regeneration while preventing adhesion recurrence is a crucial research objective aimed at enhancing clinical outcomes for women with intrauterine adhesion…
BACKGROUND: Previous studies have examined that a range of optimal serum P level during the implantation period was associated with optimal live birth rates. However, those results obtained with vaginal or intramuscular route of progesteron…
Growth hormone (GH) has been used as a co-gonadotrophin in assisted reproduction, particularly in poor ovarian responders. The application of GH has been alleged to activate primordial follicles and improve oocyte quality, embryo quality, a…
Objective To compare the efficacy of three protocols for ovarian stimulation in patients with diminished ovarian reserve during in vitro fertilization (IVF) treatment. Methods This prospective randomized study enrolled patients with diminis…
Ovarian reserve reflects both the quantity and quality of oocytes available for procreation, and is affected by many known and unknown factors. ABO blood type is related to a number of infertility processes, but it is unclear whether and ho…
OBJECTIVE: To investigate whether early embryo cleavage kinetics were affected by type of culture media. METHODS: In this prospective sibling-split study, 620 oocytes from 37 patients were randomly allocated into two groups: Cook group and…
During the last decades, many studies have shown the possible influence of sperm DNA fragmentation on assisted reproductive technique outcomes. However, little is known about the impact of sperm DNA fragmentation on the clinical outcome of …
