Introduction: Twelve percent of reproductive aged females in the United States have utilized fertility services, and it is estimated that 25% of infertility patients have ovulatory dysfunction. Clomiphene and letrozole are currently first-line treatment options for ovulatory dysfunction. These are both disqualifying medications in the U.

The efficacy of HIV pre-exposure prophylaxis (PrEP) is high in men who have sex with men, but much more variable in women, in a manner largely attributed to low adherence. This reduced efficacy, however, could also reflect biological factors. Transmission to women is typically via the female reproductive tract (FRT), and vaginal dysbiosis, genital inflammation, and other factors specific to the FRT mucosa can all increase transmission risk.

To study if stress, as measured by salivary alpha-amylase and cortisol, negatively impacts male fertility, as measured by semen parameters, pregnancy, and live birth rates. Prospective, cohort study of men enrolled in the Males, Antioxidants, and Infertility (MOXI) trial. One-hundred twelve infertile men provided first-morning salivary and semen samples at baseline.

Article Synopsis
  • The study aimed to find the best way to determine gestational age in dichorionic pregnancies conceived through assisted reproductive technologies (ART) by analyzing ultrasound data.
  • After reviewing 140 ultrasounds, the crown-rump length (CRL) of the smaller twin was found to be the best predictor of true gestational age in the first trimester, while biometry measurements were less accurate for fetal growth assessment.
  • Overall, while all methods of measuring gestational age had minor variations, they didn't significantly affect clinical outcomes, and the smaller twin's measurements were the most reliable early in pregnancy.

The female reproductive tract (FRT) is the most common site of infection during HIV transmission to women, but viral remodeling complicates characterization of cells targeted for infection. Here, we report extensive phenotypic analyses of HIV-infected endometrial cells by CyTOF, and use a 'nearest neighbor' bioinformatics approach to trace cells to their original pre-infection phenotypes. Like in blood, HIV preferentially targets memory CD4+ T cells in the endometrium, but these cells exhibit unique phenotypes and sustain much higher levels of infection.

Study Question: Do seminal plasma (SP) and its constituents affect the decidualization capacity and transcriptome of human primary endometrial stromal fibroblasts (eSFs)?

Summary Answer: SP promotes decidualization of eSFs from women with and without inflammatory disorders (polycystic ovary syndrome (PCOS), endometriosis) in a manner that is not mediated through semen amyloids and that is associated with a potent transcriptional response, including the induction of interleukin (IL)-11, a cytokine important for SP-induced decidualization.

What Is Known Already: Clinical studies have suggested that SP can promote implantation, and studies in vitro have demonstrated that SP can promote decidualization, a steroid hormone-driven program of eSF differentiation that is essential for embryo implantation and that is compromised in women with the inflammatory disorders PCOS and endometriosis.

Study Design, Size, Duration: This is a cross-sectional study involving samples treated with vehicle alone versus treatment with SP or SP constituents.

Human endometrium undergoes cyclic regeneration involving stem/progenitor cells, but the role of resident endometrial mesenchymal stem cells (eMSC) as progenitors of endometrial stromal fibroblasts (eSF) has not been definitively demonstrated. In endometriosis, eSF display progesterone (P4) resistance with impaired decidualization in vivo and in vitro. To investigate eMSC as precursors of eSF and whether endometriosis P4 resistance is inherited from eMSC, we analyzed transcriptomes of eutopic endometrium eMSC and eSF isolated by fluorescence-activated cell sorting (FACS) from endometriosis (eMSCendo, eSFendo) and controls (eMSCcontrol, eSFcontrol) and their derived primary cultures.

Human endometrium regenerates on a cyclic basis from candidate stem/progenitors whose genetic programs are yet to be determined. A subpopulation of endometrial stromal cells, displaying key properties of mesenchymal stem cells (MSCs), has been characterized. The endometrial MSC (eMSC) is likely the precursor of the endometrial stromal fibroblast.
