Ultrasound-guided aspiration of dominant follicles (≥25 mm) followed by luteinization and progesterone production during the estrous cycle in mares
(2021-01-15)
The present study was designed to evaluate luteinization rates subsequent to aspiration of dominant follicles (≥25 mm) in the absence of a functional CL (progesterone <1 ng/mL) and characterize the temporal changes in ...
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 ...
Follicular dynamics and plasma FSH and progesterone concentrations during follicular deviation in the first post-ovulatory wave in Nelore (Bos indicus) heifers
(2007-04-01)
The objective of the present study was to characterize ovarian follicular dynamics and hormone concentrations during follicular deviation in the first wave after ovulation in Nelore (Bos indicus) heifers. Ultrasonographic ...

Expression of LH receptor mRNA splice variants in bovine granulosa cells: Changes with follicle size and regulation by FSH in vitro
(Wiley-Blackwell, 2007-06-01)
In cattle, most evidence suggests that granulosa cells express LH receptors (LHR) after (or as) the follicle becomes dominant, however there is some suggestion that granulosa cells from smaller pre-dominant follicles may ...

Expression of receptors for BMP15 is differentially regulated in dominant and subordinate follicles during follicle deviation in cattle
(Elsevier B.V., 2014-01-30)
Bone morphogenetic proteins are known to be involved in determining ovulation rate in mammals. The mechanisms through which these proteins determine follicle fate are incompletely understood. In the present study, we used ...
