OBJECTIVE: Natural fluctuations of sex hormones have been shown to modulate cerebral lateralization in dichotic listening tasks. Two recent studies presented contradictory notions regarding the mechanism of this effect. Specifically, whereas Hjelmervik et al. (2012) suggested that estradiol affects lateralization by enhancing top-down processes, such as cognitive control, Hodgetts, Weis, and Hausmann, (2015) suggested that the effect was attributable to estradiol-related variations in bottom-up aspects of lateralization...

Recurrent pregnancy loss (RPL) is defined by two or more failed pregnancies and accounts for only 1-5% of pregnancy failures. Treatment options for unexplained RPL (uRPL) are limited. Previous studies suggest a link between delayed implantation and pregnancy loss. Based on this, a timely signal for rescue of the corpus luteum (CL) using human chorionic gonadotrophin (HCG) could improve outcomes in women with uRPL. This retrospective cohort study included 98 subjects with uRPL: 45 underwent 135 monitored cycles without HCG support; and 53 underwent 142 cycles with a single mid-luteal HCG injection...

Over the past few years, the use of Gonadotropin-releasing-hormone (GnRH)-agonist for final oocyte maturation in GnRH-antagonist-protocols in stimulated IVF/ICSI cycles has gained worldwide acceptance, as this approach reduces significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Final oocyte maturation with GnRH-agonist leads to sever luteolysis, which cannot be counterbalanced using standard luteal phase support with purely progesterone (P4) application and therefore administration of hCG or high doses of P4 is considered to be essential to prevent/counteract luteolysis...

STUDY QUESTION: Does bone morphogenetic protein 2 (BMP2) regulate connexin43 (Cx43) and modulate cell-cell communication in luteinized human granulosa cells? SUMMARY ANSWER: BMP2 decreases gap junction intercellular communication (GJIC) of luteinized human granulosa cells by down-regulating Cx43 expression through an activin receptor-like kinase (ALK)2/ALK3-mediated Sma- and Mad-related protein (SMAD)-dependent signaling pathway. WHAT IS KNOWN ALREADY: BMP2 and its putative receptors are highly expressed in the human corpus luteum and are involved in the process of luteolysis...

Although testosterone (T) has been characterized as universally immunosuppressive across species and sexes, recent ecoimmunology research suggests that T's immunomodulatory effects (enhancing/suppressing) depend on the organism's reproductive context. Very little is known about the immune effects of T in healthy females, and even less about how reproductive effort modulates the immune effects of T in humans. We investigated how the interaction between endogenous T and sexual activity predicted menstrual cycle-related changes in several measures of immunity: inflammation (indexed by interleukin-6, IL-6), adaptive immunity (indexed by immunoglobulin A, IgA), and functional immunity (indexed by bactericidal assay)...

INTRODUCTION: Premenstrual syndrome (PMS) is the advent of physical and psychological symptoms related to the menstrual cycle, the symptoms of this syndrome start in luteal phase and ends at the end of menstrual period. During the last decades, the patterns of PMS (PMS) have studied in a wide range. But those researches had had different methodologies and definitions and the results were not well comparable. Hence, the researchers decided to conduct a study with the aim of investigation of the prevalent of PMS among the students of the Zahedan University of Medical Sciences...

Routinely, a bolus of 5.000-10.000 IU human chorionic gonadotropin (hCG) is used for the final follicular maturation and ovulation as a standard method. HCG has the same effect of luteinizing hormone (LH) with long half-life. It has the long lutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome (OHSS). Recently, gonadotropin-releasing hormone agonist (GnRH-a) trigger has been used for the induction of final follicular maturation and ovulation with the aim of reducing the OHSS risk...

Progesterone is an essential hormone in the process of reproduction. It is involved in the menstrual cycle, implantation and is essential for pregnancy maintenance. It has been proposed and extensively used in the treatment of different gynecological pathologies as well as in assisted reproductive technologies and in the maintenance of pregnancy. Called "the pregnancy hormone", natural progesterone is essential before pregnancy and has a crucial role in its maintenance based on different mechanisms such as: modulation of maternal immune response and suppression of inflammatory response (the presence of progesterone and its interaction with progesterone receptors at the decidua level appears to play a major role in the maternal defense strategy), reduction of uterine contractility (adequate progesterone concentrations in myometrium are able to counteract prostaglandin stimulatory activity as well as oxytocin), improvement of utero-placental circulation and luteal phase support (it has been demonstrated that progesterone may promote the invasion of extravillous trophoblasts to the decidua by inhibiting apoptosis of extravillous trophoblasts)...

A retrospective, cohort study of high-risk patients undergoing IVF treatment was performed to assess if there is a difference in clinical pregnancy rate, live birth rate and the incidence of ovarian hyperstimulation syndrome, when a GnRH agonist (GnRHa) trigger with intensive luteal support is compared to human chorionic gonadotropin (hCG) with standard luteal support. The control group consisted of 382 high-risk patients having a GnRH antagonist protocol with 194 receiving an hCG trigger. All patients had ≥18 follicles ≥11mm or serum oestradiol >18,000pmol/l on the day of trigger...

In contrast to the species studied, the corpus luteum (CL) of Iberian and Eurasian lynx physiologically persists in the ovary for more than 2 years and continues to secrete progesterone. Such persistent CL (perCL) transition into the next cycle and are present in the ovary together with the freshly formed CL (frCL) of a new ovulation. To date, the mechanisms supporting such CL persistence are not known. We analyzed the potential receptivity of feline CL to sex steroids through mRNA measurements of progesterone receptor (PGR), progesterone receptor membrane components (PGRMC) 1 and 2, estrogen receptor (ESR) 1 and ESR2, G protein-coupled estrogen receptor 1 (GPER1), and androgen receptor (AR)...

Progestin concentration in plasma during the early luteal phase is crucial for endometrial function and conceptus development. We hypothesized that periovulatory gonadotrophin treatment via support of luteal function affects endometrial gene expression in horses. Effect of age was analyzed as well. Shetland mares (n = 8, age 4-25 years) were assigned to the following treatments during five consecutive cycles in alternating order following a cross-over design: treatment hCG/-: preovulatory injection of hCG, but no gonadotrophin injection at detection of ovulation, treatment -/hCG: no preovulatory gonadodrophin injection, but injection of hCG at detection of ovulation, treatment eCG/-: preovulatory injection of eCG, but no gonadotrophin injection at detection of ovulation, treatment -/eCG: no preovulatory gonadotrophin injection, but injection of eCG at detection of ovulation, treatment control: no treatment...
