Recurrent implantation failure (RIF), a important contributor to infertility in assisted reproductive technologies, is believed to be primarily to abnormal endometrial decidualization. However, its related molecular mechanisms are still inc…

OBJECTIVE: The Progestin-Primed Ovarian Stimulation (PPOS) protocol with a freeze-all strategy is increasingly used for diminished ovarian reserve (DOR) patients. While growth hormone (GH) and Kuntai capsule are proposed adjuvants, their ef…

Abstract Backgrounds: Recurrent implantation failure (RIF), a important contributor to infertility in assisted reproductive technologies, is believed to be primarily to abnormal endometrial decidualization. However, its related molecular m…

PURPOSE: To evaluate the relationships between the sperm DNA fragmentation index (DFI) and semen parameters and its application in fresh embryos via in vitro fertilization and transfer. METHODS: A retrospective propensity score matching (P…

BACKGROUND: Kuntai capsules, a traditional Chinese medicine, are speculated to improve the treatment outcomes of patients with ovarian reserve dysfunction (DOR), but existing evidence is limited. OBJECTIVE: To investigate the effects of Ku…

BACKGROUND: Fresh embryo transfer reduces waiting time and minimizes embryo cryodamage for endometriosis (EM) patients. The current prediction models for fresh embryo transfer outcomes in EM primarily rely on logistic regression, with limit…

BACKGROUND: Diminished ovarian reserve (DOR) is clinically characterized by a decrease in the number of available ovarian follicles and a decline in the quality of oocytes, accompanied by hormonal changes. Low quality of DOR oocyte leads to…

OBJECTIVE: To determine the clinical and embryo laboratory factors that affect the clinical pregnancy rate of infertile patients with endometriosis (EMs), and establish a model for predicting clinical pregnancy. STUDY DESIGN: An observatio…

BACKGROUND: Previous studies on the impact of mitochondrial DNA (mtDNA) copy number on female infertility were limited and inconsistent. METHODS: The causal relationship between mtDNA copy number and female infertility was evaluated using …

BACKGROUND: Several surveys have reported that patients treated with gonadotropin-releasing hormone antagonist (GnRH-ant) protocol showed a significantly lower rate of implantation and clinical pregnancy compared to GnRH agonist (GnRH-a) pr…

The molecular mechanism that triggers polycystic ovary syndrome (PCOS) is mysterious. Abnormal development of ovarian granulosa cells (GCs) is one of the causes of PCOS. Herein, our study was carried out using RNA-seq to detect the differen…

Polycystic ovary syndrome (PCOS) affects 8-13% of reproductive-age females worldwide and mutations or aberrant expression of androgen receptor (AR) may cause the onset of this disease. In the present study, 258 samples from Han Chinese pati…

BACKGROUND: The mechanism of recurrent implantation failure (RIF) is unclear at present and poor endometrial receptivity may be one of the leading reasons. This study aims to construct a competing endogenous RNA (ceRNA) network and identify…

Endometriosis is a common gynecological disease affecting up to 10% of women at reproductive age. Prior combined studies implied that MYH8 mutations might exist in endometriosis. Here, 152 Han Chinese samples with ovarian endometriosis were…

INTRODUCTION: Controlled ovarian hyperstimulation (COH) is essential for artificial reproduction technology (ART). This study aimed to evaluate the effects of a mild starting dosage of r-FSH ovarian stimulation after the modified prolonged …

Endometriosis is a complex and heterogeneous pre-malignant inflammatory disease harboring multiple gene mutations. Previous studies have suggested that caspase recruitment domain family member (CARD)10 and CARD11 mutations may exist in endo…

Endometriosis is a potential premalignant disorder. The underlying molecular aberrations, however, are not fully understood. A recent exome sequencing study found that 25% (10/39) of deep infiltrating endometriosis harbored cancer driver ge…
