BackgroundEmbryos derived from in vitro fertilization (IVF) single pronucleus (1PN) zygotes can achieve live births. The pronucleus size of 1PN zygotes is related to their embryonic development potential. However, these studies cannot draw …

Urinary incontinence (UI) significantly impacts the quality of life and psychological well-being of female patients. Although emerging evidence suggests potential links between endocrine-disrupting chemicals and pelvic floor disorders, prev…

The sex ratio shift was observed in peoples who underwent ART treatment. Moreover, there is limited evidence on differences in sex ratio between single frozen-thawed blastocyst morphology, insemination type and transfer days. So further res…

This study aimed to investigate the metabolite profile and inflammatory state of follicular fluid (FF) in women with stage III-IV ovarian endometriosis (OE) who underwent in vitro fertilization (IVF). A cohort of 20 consecutive patients wit…

Well-orchestrated maternal-fetal cross talk occurs via secreted ligands, interacting receptors, and coupled intracellular pathways between the conceptus and endometrium and is essential for successful embryo implantation. However, previous …

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…

Background0PN zygotes have a low cleavage rate, and the clinical outcomes of cleavage-stage embryo transfers are unsatisfactory. Blastocyst culturing is used to screen 0PN embryos, but whether the cell number of 0PN embryos on day 3 affects…

BackgroundHydrosalpinx has a negative effect on the pregnancy outcomes of in vitro fertilization and embryo transfer (IVF-ET), and the pretreatment for hydrosalpinx play an important role in improving the outcomes of IVF-ET. This study aime…

BACKGROUND: This study aimed to investigate the medroxyprogesterone acetate (MPA) + HMG protocol vs ultra-long gonadotrophin releasing hormone (GnRH) agonist protocol in patients with advanced ovarian endometriosis who received in vitro fer…

ObjectiveTo evaluate the clinical effect of mild stimulation with letrozole on pregnancy outcomes in ovulatory women undergoing frozen embryo transfer (FET) compared to natural cycle.DesignRetrospective observational study.SettingTertiary c…

BackgroundMany 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 fa…

Methods: 450 infertile patients with severe endometriosis undergoing IVF/ICSI were randomized to: medroxyprogesterone acetate +hMG; dydrogesterone+hMG; and progesterone +hMG. Ovulation was induced with a gonadotropin-releasing hormone agoni…

BACKGROUND: This study investigated the effects of medroxyprogesterone acetate (MPA) on the oocytes and embryos in patients with advanced endometriosis who had a normal ovarian reserve and tubal infertility and received controlled ovarian h…

PurposeTo explore the trends of oocyte and pregnancy outcomes over the ovulation trigger-OPU (oocyte pickup) time interval in four mainly used COH protocols.MethodsThis retrospective study was conducted between January 2013 and July 2018. T…

Background: To investigate the optimal ovulation trigger-oocyte pickup (OPU) interval of a progestin-primed ovarian stimulation (PPOS) protocol. Method: Patients with normal ovarian reserve in their first PPOS OPU cycle were enrolled in thi…

BackgroundPremature ovulation occurs at a high rate in natural-cycle in vitro fertilization (IVF), and cycle cancellation further hampers the overall efficiency of the procedure. While lower levels of estradiol (E2) are observed in preovula…

BACKGROUND Increasing the success rate of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) is a duty of clinicians that has made many seek a variety of protocols. This study was undertaken to use a liquid chromatography-ma…

Progestin-primed ovarian stimulation (PPOS) protocol has recently been demonstrated to be an novel regimen for preventing premature LH surges during controlled ovarian hyperstimulation (COH) in combination with frozen-thawed embryo transfer…

This study investigated the use of medroxyprogesterone acetate (MPA) or a short protocol for controlled ovarian hyperstimulation (COH) in patients with advanced endometriosis who have normal ovarian function, and to compare cycle characteri…

Ovarian hyperstimulation syndrome (OHSS) during ovarian stimulation is a current challenge for patients with polycystic ovarian syndrome (PCOS). Our previous studies indicated that progestin can prevent premature luteinizing hormone (LH) su…

The goal of this study is to elucidate the effects of 17β-estradiol and TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) on macrophage phenotypes in the endometriotic milieu. Co-culture of endometrial stromal cells (ESCs) and U937 cells (macropha…

Fractalkine (FKN) is involved in the immunopathogenesis of inflammatory diseases, including endometriosis. Our objective was to investigate the role of FKN in the cross-talking between endometrial stromal cells (ESCs) and U937 (macrophage l…

MiR-195, which exhibits a proliferation-inhibiting role in different tumors, has been reported to be down-regulated in the ectopic endometrium. The aim of this study was to determine the impact of miR-195 on the biological characteristic of…
