The ovarian hyperstimulation syndrome (OHSS) is an iatrogenic syndrome, which may, infrequently, become severe and evenly fatal. Until the last decade, the worldwide popularity of assisted reproductive technology (ART) and ovulation induction/controlled ovarian hyperstimulation employed in ART for either in vivo fertilization or in vitro fertilization, in the last two decades, has been accompanied by an increase in the cases of OHSS. In the last decade, the substitution of the human chorionic gonadotropin trigger with the gonadotropin-releasing hormone agonist trigger has decreased the incidence of this syndrome but did not eliminate it completely...

Polycystic ovary syndrome (PCOS), which is characterized by hyperandrogenism, is a complex endocrinopathy that affects the fertility of 9%-18% of reproductive-age women. However, the exact mechanism of PCOS, especially hyperandrogen-induced anovulation, is largely unknown to date. Physiologically, the natriuretic peptide type C/natriuretic peptide receptor 2 (CNP/NPR2) system is essential for sustaining oocyte meiotic arrest until the preovulatory luteinizing hormone (LH) surge. We therefore hypothesized that the CNP/NPR2 system is also involved in PCOS and contributes to arresting oocyte meiosis and ovulation...

OBJECTIVES: To summarize data on the accuracy and acceptability of a strategy for identifying ongoing pregnancy after medical abortion treatment using a low-sensitivity pregnancy test (LSPT). STUDY DESIGN: We searched PubMed to identify studies that evaluated the use of a single post-treatment LSPT for detection of ongoing pregnancy after treatment with mifepristone and misoprostol. We extracted, assessed, and summarized data from each study. RESULTS: We found 10 studies that evaluated 6 LSPTs with human chorionic gonadotropin detection thresholds of 1000, 1500, or 2000 mIU/ml...

As constituent factors of Piwi-interacting RNA (piRNA) pathways, Piwi proteins are essential for germline maintenance and gonadal development. Previous studies show that Piwi-piRNA pathways could be regulated by hypothalamic-pituitary-gonadal (HPG) axis, however, related studies have not been reported in marine species. Here we reported the identification of turbot (Scophthalmus maximus) piwil1 gene, which was abundantly expressed in testis and ovary in a tissue-specific manner. Phylogenetic and genomic structure analyses revealed that piwil1 was conserved in its sequence and function during vertebrate evolution...

AIM: Elevated human chorionic gonadotropin (HCG) and alpha fetoprotein (AFP) have been linked to placental dysfunction and associated morbidities. We aimed to compare the induction of labor with expectant management at term in those pregnancies for the prevention of neonatal and maternal morbidities. METHODS: Women with second trimester HCG ≥ 2 and/or AFP ≥ 2 multiples of the median, without additional maternal or fetal complications, from their 38th gestational week were offered the choice of labor induction or expectant management...

A 27-year-old male presented with a gradually increasing left scrotal mass. There was no significant past medical history. Ultrasonography of the left scrotum showed a hypoechoic, intratesticular mass with solid and cystic components. Laboratory investigations revealed normal serum levels of alpha-fetoprotein, beta human chorionic gonadotropin and lactate dehydrogenase. He underwent left high inguinal orchidectomy due to suspicion of testicular malignancy. After histopathologic examination and immunostaining, a diagnosis of high-grade primary testicular leimyosarcoma was ascertained...

Ovarian stimulation in a gonadotropin-releasing hormone (GnRH) antagonist protocol with the use of GnRH agonist for final oocyte maturation is the state-of-the-art treatment in patients with an expected or known high response to avoid or at least reduce significantly the risk for development of ovarian hyperstimulation syndrome (OHSS). Due to a shortened LH surge after administration of GnRH agonist in most patients, the luteal phase will be characterized by luteolysis and luteal phase insufficiency. Maintaining a sufficient luteal phase is crucial for achievement of a pregnancy; however, the optimal approach is still under debate...

Background: The effect of elevated progesterone level on human chorionic gonadotropin (HCG) day in in vitro fertilization cycles is controversial. Some suppose that rise in progesterone level seems to have a negative impact on implantation and pregnancy by desynchronizing the endometrium, while others disagree. Objective: To evaluate the superiority of the frozen cycle over fresh cycle on live birth in patients with elevated progesterone level on HCG day. Materials and Methods: In this double-blind, randomized clinical trial, 72 women undergoing assisted reproductive technology with elevated progesterone level (≥1...
