Precise regulation of alternative splicing (AS) of maternal mRNAs is crucial for maintaining mRNA homeostasis and for acquiring oocyte competence. However, the regulatory factors and mechanisms of AS regulating oocyte competence and human f…

Oocyte/embryo defects can result in oocyte maturation arrest, fertilization failure, embryonic arrest, and infertility as well as recurrent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) failures. However, the genet…

BACKGROUND: To evaluate whether progesterone-induced changes in endometrial thickness (EMT) affect singleton infant outcomes during frozen-thawed embryo transfer (FET) cycles. METHODS: This retrospective study analyzed 6,331 singleton live…

BACKGROUND: Clomiphene citrate effectively suppressed the negative feedback of estrogen on the hypothalamus and induces premature luteinizing hormone (LH) surge during controlled ovulation stimulation, while obese women often have impaired …

PURPOSE: To investigate how two methods for managing early miscarriage after frozen embryo transfer (FET) cycles impact live birth rates and other reproductive and perinatal outcomes in subsequent FET cycles without preimplantation genetic …

Endometriosis, particularly ovarian endometriosis (OE), is a major cause of infertility, often associated with reduced oocyte quality and impaired ovarian function. Iron overload plays a key role in OE progression. This study investigates t…

OBJECTIVE: To investigate whether the previous spontaneous miscarriages affect the cycle outcomes in in vitro fertilization and embryo transfer (IVF-ET). METHODS: Comparisons were made on the cycle characteristics and outcomes between pati…

STUDY QUESTION: Which specific groups of women would not benefit from repeated frozen embryo transfers (FETs)? SUMMARY ANSWER: Women over 45 years of age should stop treatment after three FET attempts due to the absence of further benefits…

Infants conceived with in vitro fertilization (IVF) are exposed to underlying infertility and the IVF process. High risks of adverse birth outcomes (ABOs) were observed among these infants, including preterm birth, low birth weight, macroso…

Ectopic pregnancy (EP) is increasingly found in women treated with in vitro fertilization and embryo transfer (IVF−ET). With the development of the freeze-all policy in reproductive medicine, it is controversial whether frozen embryo transf…

OBJECTIVE: The present study aimed to evaluate pregnancy and neonatal outcomes in women, with a previous history of wedge resection for interstitial pregnancy, in frozen-thawed embryo transfer (FET) cycles of IVF/ICSI. METHODS: The present…

Endometriosis (EMs) occurs in approximately 50% of women with infertility. The main causes of EMs-related infertility are follicle dysplasia and reduced oocyte quality. Iron overload occurs in ovarian follicular fluid (FF) of patients with …

PURPOSE: The purpose of this study is to assess the safety of progestin-primed ovarian stimulation (PPOS) protocol regarding the neonatal outcomes and congenital malformations in babies born after in vitro fertilization (IVF) and frozen emb…

BACKGROUND: Polycystic ovary syndrome (PCOS) is one of the most common reasons for infertility. The consensus of the treatment of infertile women with PCOS is ovulation induction (OI) for six to nine attempts before in vitro fertilization (…

OBJECTIVE: To evaluate the clinical effect of mild stimulation with letrozole on pregnancy outcomes in ovulatory women undergoing frozen embryo transfer (FET) compared to natural cycle. DESIGN: Retrospective observational study. SETTING: …

BACKGROUND: Many studies have demonstrated the positive clinical value of progestin-primed ovarian stimulation (PPOS) in patients with polycystic ovary syndrome (PCOS) who underwent assisted reproductive technology. However, the underlying …

Background: Endometrial preparation is essential in frozen-thawed embryo transfer (FET) cycles. Recent studies suggested that different endometrial preparation methods may influence obstetrical complications. However, the association betwee…

Aims: To determine the impact of advanced endometriosis (EMS) on in vitro fertilization/intracytoplasmic sperm injection and frozen-thawed embryo transfer (IVF/ICSI-FET) outcomes and analyze the influencing factors. Methods: A retrospective…

BACKGROUND: Decreased endometrial thickness (EMT) has been suggested to be associated with reduced birthweight of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) newborns. Considering the differences in ovarian stimulatio…

PURPOSE: To investigate whether progestin-primed ovarian stimulation (PPOS) can be an alternative as gonadotrophin-releasing hormone agonist (GnRHa) long protocol for infertile women with normal ovarian reserve during IVF/ICSI. METHODS: A …

INTRODUCTION: Women with polycystic ovary syndrome (PCOS) undergoing in vitro fertilization (IVF) protocols are typically characterised by an increased number of oocytes retrieved. The oocytes are often of poor quality, leading to lower pre…

OBJECTIVE: To evaluate whether endometrial thickness (EMT) change in response to progesterone has an effect on pregnancy outcomes in frozen-thawed embryo transfer (FET) cycles. DESIGN: Retrospective observational study. SETTING: Tertiary-…

RESEARCH QUESTION: Does preconception body mass index (BMI) affect neonatal outcomes in women with endometriosis who conceive with IVF? DESIGN: This retrospective study included 7086 women who delivered a singleton live birth through IVF b…

Object: Is it possible to use different progestins cotreatment with human menopausal gonadotrophin (hMG) in women with advanced endometriosis but normal ovulation during controlled ovarian hyperstimulation (COH) in vitro fertilization (IVF)…
