In contrast to most hormonal biomarkers of the follicular status, anti-Müllerian hormone (AMH) is exclusively produced by the granulosa cells of a wide range of follicles (primary to the early antral stages), presumably FSH-independently and with little susceptibility to disorders of antral follicle growth during the luteal-follicular transition. This paper summarizes the authors' clinical rese...

Microvascular changes during the development of follicles in bovine ovaries were studied by scanning electron microscopy of corrosion casts. A clear vascular plexus of ovarian follicles appeared at the stage when secondary follicles were 200-400 microns in diameter. The plexus consisted initially of a thin, roughly structured and single-layered capillary network. During follicular development, ...

BACKGROUND Several studies have reported a correlation between antral follicle count by conventional 2D transvaginal sonography and serum anti-Müllerian hormone levels. However, few studies have investigated the effectiveness of 3D SonoAVC transvaginal ultrasound technology, particularly in infertile women. Therefore, this study aims to evaluate the usefulness of three-dimensional (3D) SonoAVC ...

The acute effects of short-term glutamate administration on the number of antral follicles and ovulation rate were examined in adult goats. Neither live weight (44.5±1.3 kg) nor body condition (3.3±0.8 units) differed between the control (untreated) and glutamate-treated (0.175 mg/kg) animals (p>0.05). However, the number of antral follicles (3.4 vs. 2.1, p=0.05) and ovulation rate (2.5 vs. 1.5...

Background The aim of this study was to investigate the effect of applying the 1-mT magnetic field (MF) in the ovarian tissue vitrification. MaterialsAndMethods Ovaries of 6-8 week-old Naval Medical Research Institute female mice randomly were divided into 5 groups: V1: Ovaries that immediately after leaving of the mice body, were examined histologically (control group), V2: Ovaries that withou...

The first aim of the research conducted as part of this thesis was to investigate the expression and activities of 11PHSD enzymes in porcine mural granulosa cells and COCs from small, medium and large antral follicles, as well as from ovarian cysts. Both cloned lipHSD enzymes (11 PHSD 1 and 11PHSD2) were expressed in porcine granulosa cells however the results of the expression studies in COCs ...

STUDY QUESTION What are the direct effects of androgens on primate follicular development and function at specific stages of folliculogenesis? SUMMARY ANSWER Androgen addition altered primate follicle survival, growth, steroid and anti-Müllerian hormone (AMH) production, and oocyte quality in vitro, in a dose- and stage-dependent manner. WHAT IS KNOWN ALREADY Androgens have local actions in...

objective: the aim of this study was to evaluate the effect of sucrose on follicular survival rate and the incidence of apoptosis in rat ovarian tissue following vitrification. methods: ovaries of approximately 5-week-old female wistar rats were divided randomly into three groups: control (non-vitrified), vi (ethylene glycol + dimethyl sulfoxide) and vii (eg + dmso + 0.25 mol/lit sucrose). vit...

OBJECTIVE To assess Body Mass Index (BMI) effects on the results obtained from ICSI cycles. METHODS We studied 266 ICSI cycles performed between January 2014 and December 2016. The patients were grouped according to their BMI in: Normal (18.5-24.9), Overweight (25.0-29.9) and Obese (>30). We compared the following variables between the groups: number of antral follicles, ovarian stimulation l...
