Characterization of follicle populations in mare ovaries: From preantral to preovulatory follicles
(2015-01-01)
Introduction: The equine ovary is peculiar in that, unlike other mammalian ovaries, its germinal surface, where follicles and oocytes are found, is located at the organ’s central portion, while its conjunctive tissue and ...
Morphological and quantitative evaluation of buffalo preantral follicles in different reproductive phases
(2010)
The objective of this research was to estimate the population of preantral follicles in prepubertal (P), adult (A) and pregnant (PR) female buffaloes, as well as to observe the different degeneration types and rates of ...

Relationship between follicle size and ultrasound-guided transvaginal oocyte recovery
(Elsevier B.V., 2001-07-03)
We evaluated the relationship between follicle size and oocyte recovery (OR) using ultrasound-guided follicle aspiration. Thirty Holstein cows were subjected to OR without gonadotrophic therapy. Oocytes were recovered two ...

Evidence that fibroblast growth factor 10 plays a role in follicle selection in cattle
(Csiro Publishing, 2017-01-01)
There is evidence that regulation of follicle selection in cattle involves locally produced growth factors. In the present study, we investigated the expression of members of the fibroblast growth factor (FGF) 7 family ...
Follicle populations and gene expression profiles of Nelore and Angus heifers with low and high ovarian follicle counts
(2019-02-01)
The number of antral follicles counted (AFC) by ultrasound is associated with fertility in cattle. Cows with higher follicle count (HFC) have higher performance in reproductive-assisted technologies than cows with lower ...
Temporal interrelationships among luteolysis, FSH and LH concentrations and follicle deviation in mares
(2000-03-01)
The effect of altered LH concentrations on the deviation in growth rates between the 2 largest follicles was studied in pony mares. The progestational phase was shortened by administration of PGF2α on Day 10 (Day 0=ovulation; ...

Dynamics of follicle populations and gonadotropin concentrations in fillies age two to ten months
(Equine Veterinary Journal Ltd, 2000-11-01)
Follicle populations and concentrations of circulating gonadotropins were studied during age 2-10 months in 10 spring-born pony fillies. Blood sampling and ultrasound scanning were done every 4 days and daily for four 30 ...
