OBJECTIVE: This study aimed to evaluate factors associated with the clinical pregnancy rate in women with diminished ovarian reserve (DOR) undergoing repeated assisted reproductive technology (ART) cycles. METHODS: A retrospective analysis…
Fertility in women decreases with age, but the molecular basis for age-related, unexplained infertility remains elusive. Here, we reveal distinct transcriptome changes in oocytes and surrounding cumulus cells from women in their mid-thirtie…
BACKGROUND: Tubal ectopic pregnancy (TEP) is a common and serious obstetric complication with unclear pathogenesis. This study aims to use single-cell RNA sequencing (scRNA-seq) to analyze immune cell composition and functional changes in i…
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 …
BACKGROUND: Unilateral twin ectopic pregnancy is extremely rare in natural pregnancy, with an incidence rate of only 1 in 200,000-2,500,000, represents a major health risk for reproductive-aged women, leading to even life-threatening compli…
BACKGROUND: Worldwide, frozen embryo transfer (FET) has become a new strategy for the treatment of infertility. The success of FET is closely related to endometrial receptivity. Does uterine artery Doppler during the implantation window pre…

BACKGROUND: With the development of embryo freezing and warming technology, frozen-thawed embryo transfer (FET) has been widely utilized. However, studies investigating the association between cryopreservation duration and FET outcomes are …
Polycystic ovary syndrome (PCOS) is one of the most common endocrine metabolic disorders characterized by hyperandrogenism, polycystic ovaries and ovulatory dysfunction. Several studies have suggested that the aberrant expression of microRN…
BACKGROUND: Excessive gestational weight gain (GWG), which is associated with adverse long-term effects on the health of the offspring, has become a major clinical problem. Accumulating evidence indicates that the ovary kisspeptin/GPR54 sys…
Background: This study evaluated the expression of cellular FLICE-like inhibitory protein (cFLIP) in granulosa cells (GCs) obtained from in vitro fertilization-embryo transfer patients with advanced endometriosis. Methods: A total of 267 pa…
Background: Leiomyomatosis peritonealis disseminate (LPD) is a rare benign entity, but its histological origin remains unclear. Cases: An unusual DPL case which was diagnosed at 4 years after her initial laparoscopic uterine myomectomy with…
Staphylococcus aureus (Sau) strains are a main cause of disease, including nosocomial infections which have been linked to the production of biofilms and the propagation of antibiotic resistance strains such as methicillin-resistant Staphyl…
BACKGROUND: The levonorgestrel intrauterine system, Mirena®, is widely used for contraception and the treatment of idiopathic menorrhagia. Here, we reported one case of acute urticaria following Mirena® implantation to increase the awarenes…
Objective To investigate the effect of different down-regulation protocol on the in vitro fertilization-embryo transfer (IVF-ET) outcomes in infertile patients with endometriosis (EMs). Methods A retrospective case control study was perform…
