BACKGROUND: Trends toward earlier age at menarche, the starting point in women’s reproductive lifespan, have been observed globally. Whether an earlier age at menarche influences Anti-Müllerian hormone (AMH), a clinical indicator of ovarian…

BACKGROUND: Nerve growth factor (NGF), which acts on receptors tropomyosin receptor kinase A and p75 neurotrophic receptor, is a member of neurotrophin family and a kind of secretory polypeptides. METHODS: A comprehensive literature search…

BACKGROUND: Natural cycle in vitro fertilization (NC-IVF) represents a convenient and safe assisted reproductive technology, making it particularly advantageous for patients with poor ovarian response (POR). This research evaluates the effe…

BACKGROUND: Oocyte vitrification, a widely utilized assisted reproductive technology for fertility preservation, can address emergencies arising from the unavailability of sperm from the male partner on the day of oocyte retrieval. However,…

PURPOSE: This study aimed to investigate the impact of obstructive sleep apnea (OSA) on in vitro fertilization (IVF) and embryo transfer outcomes in infertile patients with polycystic ovary syndrome (PCOS). METHODS: We conducted a prospect…

OBJECTIVES: This study aimed to explore potential differences in efficacy between vaginal progesterone (VPG) and VPG + oral progesterone (OPG) for luteal-phase support in hormone replacement therapy-frozen embryo transfer (HRT-FET) cycles. …

BACKGROUND: Imbalances in alkali elements (AEs) and alkaline earth elements (AEEs) cause reproductive disorders. However, it remains unclear whether AEs/AEEs in follicular fluid have a relationship with the serious reproductive disorder kno…

BACKGROUND: The utilization of a double trigger, involving the co-administration of gonadotropin-releasing hormone agonist (GnRH-a) and human chorionic gonadotropin (hCG) for final oocyte maturation, is emerging as a novel approach in gonad…

PURPOSE: This study aimed to evaluate the comparative reproductive outcomes of ovarian stimulation combined with intrauterine insemination using partner's sperm (OS-IUI) in eumenorrheic and normogonadotropic oligomenorrheic women. METHOD: …

BACKGROUND: Ensuring women's sexual and reproductive health (SRH) is a fundamental human right and key to 2030 agenda of the UN Sustainable Development Goals (SDGs), yet limited evidence exists on SRH in China, including national estimates …

Due to the influence of economic, social and many other factors, there are more and more reproductive problems. Originally introduced for managing male factor infertility, intracytoplasmic sperm injection had become the most commonly used f…

STUDY QUESTION: To construct prediction models based on the Bayesian network (BN) learning method for the probability of fertilization failure (including low fertilization rate [LRF] and total fertilization failure [TFF]) in assisted reprod…

BACKGROUND: According to the latest practice committee document, in vitro maturation (IVM) is a simple and safe procedure, especially in patients with polycystic ovary syndrome (PCOS). Does switching from in vitro fertilization (IVF) to IVM…

BACKGROUND: Only a small number of studies have reported the use of progesterone vaginal gel in combination with dydrogesterone as part of the antagonist protocol for fresh embryo transfer. Therefore, this study aimed to compare the effects…

BACKGROUND: Ectopic pregnancy is more common amongst assisted reproduction cycles and is a cause of significant maternal morbidity. Few predictive markers exist to help identify and modify risk of ectopic pregnancy in preparing for embryo t…

OBJECTIVE: To study biomarkers to develop a novel diagnosis model for endometriosis and validate it using clinical samples. DESIGN: We used publicly available data sets and weighted gene coexpression network analysis to identify differenti…

BACKGROUND: To compare the efficacy and safety of follitropin delta in its individualized fixed-dose regimen with follitropin alfa in a conventional adjustable dosing regimen in Chinese women.  METHODS: This was a subgroup analysis of the r…

PURPOSE: This study aimed to develop a risk prediction of fertilization disorders during the in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). METHODS: A retrospective study was performed with 106,728 fresh embryo IVF/ICS…

PURPOSE: To establish a mathematical model for assessing the true ovarian reserve based on the predicted probability of poor ovarian response (POR). METHODS: In this retrospective cohort study, a total of 1523 GnRH-antagonist cycles in 201…

BackgroundEctopic pregnancy (EP) is a serious complication of assisted reproductive technology (ART). However, there is no acknowledged mathematical model for predicting EP in the ART population.ObjectiveThe goal of the research was to esta…

Cysteine‑rich angiogenic inducer 61 (CCN1/Cyr61) is a prompt response transcription product activated by growth factors. As a member of the CCN family, it mediates cell survival, proliferation, differentiation, migration, adhesion and synth…

BACKGROUND: There is limited literature investigating the effects of body mass index (BMI) and androgen level on in vitro fertilization (IVF) outcomes with a gonadotropin-releasing hormone (GnRH)-antagonist protocol in polycystic ovary synd…
