Background: Polycystic ovary syndrome (PCOS) is characterized by substantial inter-individual variability in ovarian sensitivity to recombinant follicle-stimulating hormone (rFSH) during controlled ovarian stimulation (COS). Clinically appl…

BACKGROUND: Adenomyosis, an estrogen-dependent condition characterized by endometrial invasion into the myometrium, is associated with reduced live birth rates and increased miscarriage risk in women undergoing assisted reproductive technol…

To compare the efficacy of different COH protocols on pregnancy outcomes in adenomyosis patients. A real-world retrospective cohort study analyzed 1486 IVF-ET cycles in adenomyosis patients who received COH regimens between 2018 and 2021. P…

OBJECTIVE: To compare the efficacy of different COH protocols on pregnancy outcomes in adenomyosis patients. STUDY DESIGN: A real-world retrospective cohort study analyzed 1486 IVF-ET cycles in adenomyosis patients who received COH regimen…

BACKGROUND: Previous studies have shown that due to the presence of endometrium progesterone resistance in patients with endometriosis, it is considered that higher levels of progesterone may be required to achieve live birth during program…

Abstract CCCTC-binding factor (CTCF), a highly versatile transcriptional regulator and chromatin architectural protein, plays a pivotal role in mammalian development. In this study, we investigated the function of CTCF in uterine biology du…

OBJECTIVES: To evaluate the association of GGN repeat polymorphism of androgen receptor (AR) with ovarian reserve and ovarian response in controlled ovarian stimulation (COS). METHODS: This genetic association study was conducted among a t…

BACKGROUND: Intra-abdominal hemorrhage (IAH) is a rare but potentially life-threatening complication of ultrasound-guided transvanginal oocyte pick up (OPU). Despite the widespread use of OPU in assisted reproductive technology, minor hemor…

Controlled ovarian stimulation (COS) is one of the most vital parts of in vitro fertilization-embryo transfer (IVF-ET). At present, no matter what kinds of COS protocols are used, clinicians have to face the challenge of selection of gonado…

In order to find out to what extent ovarian aging could be compensated by the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatments, a total of 4102 women above the age of 35 undergoing 6489 complete cycles from 2009…

OBJECTIVE: To investigate the impact of luteinized unruptured follicles (LUF) on clinical outcomes of frozen/thawed embryo transfer (FET) of blastocysts. METHODS: In this retrospective cohort study, 2,192 patients who had undergone blastoc…

We aimed to explore the clinical effects of the endometrial preparation protocol for frozen-thawed embryo transfer (FET) in women with endometrial polyps. This retrospective study was performed at the Reproductive Medicine Centre of the Fir…

OBJECTIVE: To compare the incidence of recurrence between a cohort with a high number (≥6) of endometrial polyps (EPs) and a single-EP cohort among reproductive-age patients after polypectomy. DESIGN: Prospective observational cohort study…

PURPOSE: The objective of this study is to investigate the effect of 2, 5, and 20 % O2 on post-thaw day 3 human embryo culture until blastocyst stage. METHODS: One hundred fifty-five day 3 human embryos were used. One hundred twenty out of…

BACKGROUND: Shift work disrupts the circadian rhythm and may cause menstruation disorders. This study assessed the impact of shift work on menstrual cycle in a population of Chinese nurses. METHODS: Questionnaires on menstrual characterist…

The aim of this study was to investigate the effect of surgical intervention on the expression of leukemia inhibitory factor (LIF) and L-selectin ligand in the endometrium of patients with hydrosalpinx during the implantation window. A tota…

To investigate the clinical importance of increased integrin αvβ3 expression in the endometrium following the surgical treatment for hydrosalpinx, a total of 60 patients with hydrosalpinx and 30 patients with fallopian tube obstruction were…

BACKGROUND: The aim of the study was to determine the efficacy of in vitro fertilization and embryo transfer (IVF-ET) in patients with hyper-response to ovulation induction for intrauterine insemination (IUI). METHODS: Patients with polycy…
