Prostaglandin E (PGE) has contradictory effects in many organs. It may have proinflammatory, anti-inflammatory, or anti-fibrotic roles, depending on the type of receptors to which it binds. By signaling through its receptors EP2 and EP4, PGE mediates anti-inflammatory and anti-fibrotic actions. Read More

Study Question: Are there any differences in the molecular characteristics of the luteal granulosa cells (GC) obtained from stimulated versus non-stimulated (natural) IVF cycles that may help explain the defective luteal phase in the former?
Summary Answer: Luteal GC of stimulated IVF cycles, particularly those of agonist-triggered antagonist cycles, are less viable ex vivo, express LH receptor and anti-apoptotic genes at lower levels, undergo apoptosis earlier and fail to maintain their estradiol (E2) and progesterone (P4) production in comparison to natural cycle GC.
What Is Known Already: Luteal function is defective in stimulated IVF cycles, which necessitates P4 and/or hCG administration (known as luteal phase support) in order to improve clinical pregnancy rates and prevent miscarriage. The luteal phase becomes shorter and menstruation begins earlier than a natural cycle if a pregnancy cannot be achieved, indicative of early demise of corpus luteum (premature luteolysis). Read More

Polycystic ovary syndrome (PCOS), known as a common endocrine disorder among females, plagues many PCOS patients. The current study aimed to explore the correlations of sex hormone-binding globulin (SHBG) polymorphisms with the outcome of in vitro fertilization-embryo transfer (IVF-ET) in PCOS patients. PCOS patients who underwent IVF-ET and patients with non-PCOS-related infertility were selected in the study. Read More

The aim of this study was to investigate the effect of orexin B (OXB) on progesterone (P4) and androstenedione (A4) secretion by porcine endometrial and myometrial tissue explants and on the expression of key steroidogenic proteins and enzymes involved in steroid production. The hormones secretion and the expression of steroidogenic acute regulatory protein (StAR), P450 side-chain cleavage enzyme (CYP11A1) and 3β-hydroxysteroid dehydrogenase (HSD3B1) was analyzed on days 10 to 11, 12 to 13, 15 to 16, 27 to 28 of pregnancy and during the luteal phase of the oestrous cycle (days 10 to 11). Endometrial and myometrial explants were cultured in vitro in the presence of OXB (1, 10 or 100 nM) and OXB (1, 10 or 100 nM) with 1 µM of JNJ (OX2R antagonist). Read More

Premenstrual dysphoric disorder (PMDD) is a cluster of severe affective symptoms recurring during the luteal phase of the menstrual cycle, and it affects up to 8% of menstruating women. In Denmark, this disorder is often overlooked.

Menstrual cycle phase has long been thought to modulate thermoregulatory function. However, information pertaining to the effects of menstrual phase on time-dependent changes in whole-body dry and evaporative heat exchange during exercise-induced heat stress and the specific heat load at which menstrual phase modulates whole-body heat loss remained unavailable. We therefore used direct calorimetry to continuously assess whole-body dry and evaporative exchange in twelve habitually active, non-endurance trained, eumenorrheic females (21±2 years) within the early-follicular, late-follicular and mid-luteal menstrual phases during three, 30-min bouts of cycling at increasing fixed exercise intensities of 40% (Low), 55% (Moderate) and 70% (High) V̇O, each followed by a 15-min recovery, in hot, dry conditions (40°C, 15% relative humidity).
