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 ...
Morphological and quantitative evaluation of buffalo preantral follicles in different reproductive phases
(2010-01-01)
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 ...
Viability of primordial follicles derived from cryopreserved ovine ovarian cortex tissue
(Elsevier B.V., 2009-05-01)
Objective: To develop an efficient technique to preserve primordial follicles from cryopreserved ovarian tissue.Design: Frozen-thawed and fresh preantral follicles were mechanically isolated for viability testing, and their ...
Neonatal exposure to bisphenol A reduces the pool of primordial follicles in the rat ovary
(Pergamon-Elsevier Science Ltd, 2010-12)
We evaluated whether exposure to bisphenol A (BPA) disrupts neonatal follicle development in rats. From postnatal day 1 (PND1) to PND7, pups received corn oil (control), diethylstilbestrol (DES20: 20 μg/kg-d, DES0.2: 0.2 ...
Restoration of fresh cat ovarian tissue function by autografting to subcutaneous tissue: A pilot study
(2018-01-01)
Ovarian tissue transplantation could be a valuable technique for the preservation of endangered animals. The domestic cat affords an adequate experimental model for studies aimed at wild felids due to its phylogenetic ...
First characterization of preantral follicles in the ovaries of adult alpaca
(Instituto de Investigaciones en Ciencias de la Salud, 2019)
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 ...
