This clinical and laboratory investigation is devoted to the study of the levels and correlation between the total gonadotropins and antigonadotropin factors excreted in the urine of 10-18-year-old girls. There was found a correlation between the excretion of total gonadotropins and the concentration of their inhibitors. Periods of the greatest fall of the antigonadotropin level corresponded to the peaks of gonadotropin activity.

This study aims to investigate the expression pattern of human chorionic gonadotropin (hCG) in the tissue of endometrioid type endometrial cancer (EEC) using immunohistochemistry, and also to investigate the effect of hCG expression pattern on prognosis and survival in EEC. We evaluated patients who were operated between 2010 and 2020 in the obstetrics and gynecology clinic of our center due to EEC. In total, 194 women were determined to be in either the hCG-negative group (n=137) or the hCG-positive group (n=57).

Background: Noninvasive perinatal testing is a new method of screening for aneuploidy called cell-free DNA (cfDNA). Fetal fraction (FF) plays a crucial role in assessing the reliability of aneuploidy detection through noninvasive perinatal testing.
Objective: We aimed to investigate the association between the amount of FF in cfDNA testing and adverse pregnancy outcomes.

Myo-inositol plays a vital role in human health, functioning as a second messenger of FSH and facilitating the transport of glucose into the cell. Consequently, myo-inositol is regularly utilized in the treatment of polycystic ovary syndrome (PCOS), wherein it acts upon metabolic factors, improving insulin sensitivity and reducing total androgen levels. Patients with PCOS frequently suffer from infertility; thus, the use of myo-inositol has been explored in improving assistive reproductive technique (ART) procedures.

Resveratrol can beneficially affect growth and follicle development and lead to improved sperm function parameters in pre-clinical studies, while information from clinical studies is still inconclusive. This study aims to evaluate the biological and clinical impact of a resveratrol-based multivitamin supplement on level II assisted reproduction cycles (IVF and intracytoplasmic sperm injection [ICSI]). A retrospective, case-control study, involving 70 infertile couples undergoing IVF/ICSI cycles, was conducted at the Assisted Reproductive Center, Obstetrics and Gynecology Unit-Villa Sofia-Cervello Hospital in Palermo.

We aimed to evaluate the reproductive efficiency of Nelore cows in fixed-time artificial insemination (FTAI) programs with early resynchronization. A total of 468 Nelore cows were divided into two experimental groups: R30-conventional resynchronization at 30 days ( = 234); R22-early resynchronization at 22 days ( = 234). Both groups followed a synchronization protocol using intravaginal progesterone devices combined with the administration of steroids and gonadotropins.
