The protective effects of astaxanthin on pre-antral follicle degeneration in ovine vitrified/warmed ovarian tissue.

Cryobiology, 2023
This study assesses the protective effects of astaxanthin (AST) against vitrification/warming-induced cryoinjuries of ovarian tissue slices in sheep. Cortical slices of slaughterhouse acquired-ovine ovaries were randomly distributed in different groups ...

The Effect of Radiation Emitted by Cell Phone on The Gelatinolytic Activity of Matrix Metalloproteinase-2 and -9 of Mouse Pre-Antral Follicles during In Vitro Culture

Cell journal, 2019
Objective The unfavorable effects of electromagnetic radiation (EMR) emitted by the cell phone on reproduction health are controversial. Metalloproteinases play a vital role in ovarian follicle development.

Effects of new synthetic cryoprotectant agents on histological characteristics of various classes of vitrified bovine pre-antral follicles

Veterinary Research Forum, 2019
Previous studies have reported many discrepancies about the best type and concentration of cryoprotective agents (CPAs) and biological variability among various pre-antral follicle classes after cryopreservation of ovarian tissue.

Concentration-dependent effects of allopregnanolone on bovine pre-antral follicles in ovarian cortical tissue cultured in vitro.

Theriogenology
Allopregnanolone (ALLO) is a neuroactive steroid derived from progesterone that plays well-established roles in the nervous system. However, its impact on ovarian physiology remains underexplored.

Melatonin and cyclic adenosine monophosphate enhance the meiotic and developmental competence of porcine oocytes from early antral follicles during in vitro growth and pre-maturation culture.

Theriogenology
Melatonin has been studied for its ability to improve oocyte quality and modulate cyclic adenosine monophosphate (cAMP) production. However, the effects of melatonin on the in vitro growth (IVG) of oocyte-cumulus-granulosa complexes (OCGCs) derived from ...
