Prenatal hyperandrogenism induces alterations that affect liver lipid metabolism [PDF]

, 2016
Prenatal hyperandrogenism is hypothesized as one of the main factors contributing to26 the development of polycystic ovary syndrome (PCOS). PCOS patients have high risk27 of developing fatty liver and steatosis.

Isolation and characterization of preantral follicles from foetal bovine ovaries [PDF]

Veterinary Quarterly, 1994
A simple, mechanical method is described for the isolation of preantral follicles from bovine foetuses of 220-280 days of gestation. On average, 2918 + 621 (s.d.) preantral follicles were isolated per ovary. The isolated preantral follicles were characterized on the basis of the morphological appearance of the surrounding granulosa cells, the number of

In Vitro Gamete Production in Mammals: Decades of Pioneering Approaches in Germ Cell and Stem Cell Biology Supporting Innovative Discovery and Expansion of Human Reproductive Potential

Molecular Reproduction and Development, Volume 92, Issue 12, December 2025.
ABSTRACT During recent decades a myriad of approaches have emerged for generating surrogate gametes or achieving in vitro gametogenesis (IVG). The most recent approaches to IVG include the development of increasingly complex culture systems, use of companion cells combined with germ line cells in two‐ or three‐dimensional configurations, derivation of ...

Androgen stimulates growth of mouse preantral follicles in vitro: Interaction with follicle-stimulating hormone and with growth factors of the TGFβ super family [PDF]

, 2017
Androgens are essential for the normal function of mature antral follicles but also have a role in the early stages of follicle development. Polycystic ovary syndrome (PCOS), the most common cause of anovulatory infertility, is characterized by androgen ...

The Regulation of Apoptosis in Preantral Ovarian Follicles

Neurosignals, 2000
Less than 1% of ovarian follicles ever mature to ovulation. The remainder undergo atretic degeneration via apoptosis during development. Though the regulation of antral and preovulatory survival has been studied for many years, very little is known about the regulation of survival and development of preantral follicles.

The Critical Role of Enhanced OXPHOS and Mitochondrial Hyperpolarization in Simulated Microgravity‐Induced Oocyte Maturation Arrest

Advanced Science, Volume 12, Issue 38, October 13, 2025.
Simulated microgravity induces distinct mitochondrial hyperactivation patterns‐elevated OXPHOS and MMP‐which accelerate meiosis without SAC failure but delays MTOC coalescence, leading to spindle defects and meiotic arrest. Prolonging M‐phase restores MTOC assembly and oocyte maturation.

The Impact of Melatonin Supplementation on Various Aspects of Polycystic Ovary Syndrome: A Systematic Review and Meta‐Analysis

Health Science Reports, Volume 8, Issue 10, October 2025.
ABSTRACT Background and Aims Polycystic ovary syndrome (PCOS) is a prevalent gynecological condition affecting women of reproductive age, with implications for multiple aspects of women's health. Recent research indicates that melatonin (MLT) may enhance several dimensions of this syndrome via various mechanisms. Consequently, this study was undertaken
