Transition to the ovulatory season in mares: An investigation of antral follicle receptor gene expression in vivo

GMA Ishak, GA Dutra, GDA Gastal… - Molecular …, 2019 - Wiley Online Library
The inability to obtain in vivo samples of antral follicle wall layers without removing the
ovaries or sacrificing the animals has limited more in‐depth studies on folliculogenesis. In …

Molecular and functional characteristics of dominant follicles during spring transition in mares: a review.

ED Watson, BSE Bae SungEun, DG Armstrong - 2003 - cabidigitallibrary.org
Many mares enter a period of spring transition between winter anoestrus and cyclicity when
follicles may reach preovulatory size, yet fail to ovulate. The aim of the present study was to …

Relationships between follicular fluid composition and follicular/oocyte quality in the mare

N Gérard, G Duchamp, M Magistrini - Livestock Production Science, 1999 - Elsevier
The ovarian physiology of the mare is an interesting model. Actually, we could highlight that
in contrast with other domestic mammals, no preovulatory LH surge occurs in this species …

Characterization of morphology and angiogenesis in follicles of mares during spring transition and the breeding season.

ED Watson, MO Al-Zi'abi - Reproduction (Cambridge, England), 2002 - europepmc.org
The mare is a seasonal breeder and undergoes a period of ovarian transition in spring
between winter anoestrus and cyclicity. During spring transition LH concentrations are low …

Intrafollicular content of luteinizing hormone receptor, α-inhibin, and aromatase in relation to follicular growth, estrous cycle stage, and oocyte competence for in vitro …

G Goudet, F Belin, J Bézard, N Gérard - Biology of reproduction, 1999 - academic.oup.com
The intrafollicular content of LH receptor, α-inhibin, and aromatase are known good
indicators of follicular status. We investigated the amounts of these proteins in granulosa …
