Selective progesterone receptor modulators (SPRMs) are steroid progesterone receptor ligands able to induce agonistic or antagonistic activities. Mifepristone, the class leader, was primarily used for pregnancy termination from the 1980s. Emergency contraception with extended activity was the second major development 30 years later, with mifepristone in some countries and ulipristal acetate world-wide. More recently, ulipristal acetate was released for the treatment of myoma-related uterine bleeding. In addition to a very rapid cessation of bleeding, SPRMs allow a decrease in myoma volume, as do gonadotropin releasing hormone analogs...

RFamide-related peptide-3 (RFRP-3), the mammalian ortholog of gonadotropin-inhibitory hormone (GnIH), has been proposed as a key inhibitory regulator of mammal reproduction. Our previous studies have demonstrated that RFRP-3 inhibited the expression of proliferation-related proteins in porcine granulose cells (GCs), but the inhibitory mechanism causing this has not been discovered. Here, we aim to elucidate the underlying mechanism and determine the cell cycle regulatory sites of action of RFRP-3 on porcine GC proliferation...

We investigated a series of uracil analogues by introducing various substituents on the phenyl ring of the N-3 aminoethyl side chain and evaluated their antagonistic activity against human gonadotropin-releasing hormone (GnRH) receptors. Analogues with substituents at the ortho or meta position demonstrated potent in vitro antagonistic activity. Specifically, the introduction of a 2-OMe group enhanced nuclear factor of activated T-cells (NFAT) inhibition up to 6-fold compared to the unsubstituted analogue...

BACKGROUND: Recent rapid advances in assisted reproductive health technologies enables couples with subfertility to conceive through various intervention. Majority of treatment modalities target the female partner. However it is important to identify and treat male factor subfertility right at the outset. We report a case of isolated follicle stimulating hormone deficiency resulting in azoospermia and primary subfertility. CASE PRESENTATION: A 28 year otherwise healthy male presented with primary subfertility with a healthy female counterpart...

In the case of primary male hypogonadism (HG), only testosterone (T) replacement therapy (TRT) is possible whereas when the problem is secondary to a pituitary or hypothalamus alteration both T production and fertility can be, theoretically, restored. We here systematically reviewed and discussed the advantages and limits of medications formally approved for the treatment of HG. Areas covered: Data derived from available meta-analyses of placebo controlled randomized trials (RCTs) were considered and analyzed...

Background: An abnormality in pulse amplitude and frequency of gonadotropin releasing hormone (GnRH) secretion is the most characteristics of polycystic ovarian syndrome (PCOS). On the other hand, arginine-phenylalanine-amide (RFamide)-related peptide-3 (RFRP3) inhibits the secretion of GnRH in mammalian hypothalamus. The current study performed in order to investigate the expression of RFRP3 mRNA in the dorsomedial hypothalamic nucleus (DMH) after the induction of PCOS in a rat model of constant light exposure, and the possible role of parity on occurrence of PCOS...

Straw colored pleural fluid with raised adenosine deaminase (ADA) levels in young healthy adults usually raises suspicion of tuberculosis, sometimes leading to laxity in carrying thorough physical examination and missing out some important clues with potential disastrous consequences. A 35-year-old male was diagnosed to have left pleural effusion and anti-tubercular treatment was started on the basis of straw colored, lymphocyte-predominant pleural fluid with significantly raised ADA levels. When there was no improvement after 1 month of treatment he was investigated further and found to have a mediastinal mass along with hydro-pneumothorax...

Reproduction in marine fish is generally tightly linked with water temperature. Consequently, when adults are exposed to projected future ocean temperatures, reproductive output of many species declines precipitously. Recent research has shown that in the common reef fish, Acanthochromis polyacanthus, step-wise exposure to higher temperatures over two generations (parents: +1.5°C, offspring: +3.0°C) can improve reproductive output in the F2 generation compared to F2 fish that have experienced the same high temperatures over two generations (F1 parents: +3...

Pregnancy remains a significant health risk to women in both developed and underdeveloped countries. Worldwide, 10 to 20 million women have pregnancy complications including ectopic pregnancy, preterm birth, gestational diabetes mellitus, and hypertensive states, including preeclampsia. Despite advancements in women's health research, there is a large gap in the diagnostic tools available to screen, diagnose, and monitor these conditions. Herein, we examine existing diagnostic tools, such as the human chorionic gonadotropin discriminatory zone, cervicovaginal fetal fibronectin, sFlt-1:PlGF ratio, and glucose tolerance testing...

Aromatase deficiency (AD) is a very rare disorder resulting from mutations in the CYP19A1 gene encoding aromatase, a cytochrome P450 enzyme that plays a pivotal role in androgen conversion to estrogens. AD is inherited in an autosomal recessive trait, and to date only 35 cases have been described in the literature. Herein, we depict a new patient reared as a male, who presented at the age of 21 years with no palpable testis, hypoplastic scrotum, penis-like phallus (3 cm), and penoscrotal hypospadias. The patient was born to consanguineous parents, his karyotype was 46,XX, and SRY was negative...
