Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Intrinsic differences in mTOR activity mediates lineage-specific responses to cyclophosphamide in mouse and human granulosa cells

Journal of Ovarian Research
Background Cyclophosphamide (CTX) often induces oocyte and granulosa cell injury, leading to fertility loss in young female cancer survivors. Deciphering the mechanisms underlying follicular cell injury could offer novel insights into fertility ...

Peroxiredoxin 4 protects against ovarian ageing by ameliorating d-galactose-induced oxidative damage in mice

Cell Death and Disease, 2020
Peroxiredoxin 4 (Prdx4), a member of the Prdx family, is a vital ER-resident antioxidant in cells. As revealed in our previous study, Prdx4 expression was detected in ovarian granulosa cells and was closely related to ovarian function.

Modern competency‐based teaching of human sexual development

Anatomical Sciences Education, EarlyView.
Abstract Embryology is an integral part of anatomy and a key subject in basic medical education. The development of the sexual tract, which is closely associated with the formation of the urinary tract and the organs of continence, is particularly complex and relevant for many medical disciplines.

METTL3 prevents granulosa cells mitophagy by regulating YTHDF2-mediated BNIP3 mRNA degradation due to arsenic exposure

Ecotoxicology and Environmental Safety
The ovary is an important reproductive and endocrine organ for the continuation of the species and the homeostasis of the body's internal environment. Arsenic exposure is a global public health problem.

Ovarian follicle selection and granulosa cell differentiation

Poultry Science, 2015
The reproductive strategy for avian species that produce a sequence (or clutch) of eggs is dependent upon the maintenance of a small cohort of viable, undifferentiated (prehierarchal) follicles. It is from this cohort that a single follicle is selected on an approximate daily basis to initiate rapid growth and final differentiation before ovulation ...

Predictors of Recurrence of Ovarian Granulosa Cell Tumors

International Journal of Gynecological Cancer, 2009
The prognosis of granulosa cell tumors (GCTs) is overall favorable, but a proportion of patients will experience recurrence. We report one of the largest series of patients with GCT for whom clinical, morphologic, and immunohistochemical markers have been assessed for their roles as predictors of recurrence.Patients with the diagnosis of GCT were ...

Porcine oocyte maturation in vitro : role of cAMP and oocyte-secreted factors: a practical approach [PDF]

, 2016
Polyspermy or the penetration of more than one sperm cell remains a problem during porcine in vitro fertilization (IVF). After in vitro culture of porcine zygotes, only a low percentage of blastocysts develop and their quality is inferior to that of in ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.
