Preantral follicle population and distribution in the horse ovary [PDF]

Reproduction and Fertility, 2022
Characterization of the ovarian preantral follicle population is a necessary step to improve understanding of folliculogenesis and ovarian physiology. Therefore, in the present study, the preantral follicle population in the equine ovary in young and old

Characterization of preantral follicle clustering and neighborhood patterns in the equine ovary [PDF]

PLoS ONE, 2022
Understanding the transition from quiescent primordial follicles to activated primary follicles is vital for characterizing ovarian folliculogenesis and improving assisted reproductive techniques.

In Vitro Development of Mouse Preantral Follicle with Using Amniotic Membrane Extract-Loaded Hydrogels [PDF]

International Journal of Fertility and Sterility
An artificial ovary based on the alginate (ALG) hydrogel has been widely implemented to preserve prepubertal femalefertility. However, this platform is not fully capable of successful an ovary microenvironment simulation for follicledevelopment, holding ...

Letrozole increases preantral follicle growth and decreases estradiol production without impairing follicle survival [PDF]

Journal of Ovarian Research, 2022
Background Letrozole has been reported to be effective in treating anovulation, preventing ovarian hyperstimulation syndrome (OHSS), and retrieving oocytes in breast cancer patients.

DTPA disrupts development of preantral ovarian follicles in vitro [PDF]

Reproduction and Fertility
Dietary zinc deficiency disrupts fertility in vivo by impairing oocyte and embryo development near ovulation. Acute treatment of newborn ovaries with a strong intracellular chelator (TPEN), which preferentially binds zinc, disrupts follicular development.

Development of Mouse Preantral Follicle after In Vitro Culture in A Medium Containing Melatonin [PDF]

Cell Journal, 2015
Objective: Improvements in cancer treatment have allowed more young women to survive. However, many cancer patients suffer from ovarian failure. Cryopreservation is one of the solutions for fertility restoration in these patients. The cryopreservation of

Biochemical and immunohistochemical examination of the effects of ephedrine in rat ovary tissue [PDF]

Acta Cirúrgica Brasileira, 2023
Purpose: It was aimed to investigate the biochemical and immunohistochemical effects of ephedrine (EPH) in bilateral ovariectomized rats. Methods: Twenty-four Sprague Dawley female rats were divided into three groups: control group: The abdomen was ...

Review: Roles of follicle-stimulating hormone in preantral folliculogenesis of domestic animals: what can we learn from model species and where do we go from here?

Animal, 2023
The pituitary gonadotropin FSH is a glycoprotein critical for the development of ovarian follicles. Upon binding to its G protein-coupled membrane receptor located on the granulosa cells of ovarian follicles, FSH elicits a cascade of downstream ...
