Pattern of follicular development in sheep subjected to ovarian superstimulation after follicular ablation by laparoscopic ovum pick-up
(Univ Federal Santa Maria, 2017-01-01)
The aim of this study was to determine the pattern of follicular development in ewes following ablation of all follicles associated with ovarian superstimulatory treatment. After confirmation of reproductive cyclicity using ...
Prostaglandin receptors (EP2 and EP4) and angiotensin receptor (AGTR2) mRNA expression increases in the oviducts of Nelore cows submitted to ovarian superstimulation
(2014)
Many peptides are responsible for the coordination of muscle contraction, secretion and ciliary beating of the oviduct epithelium to allow the transport of gametes and embryos, including vascular endothelial growth factors ...
Ovarian superstimulation using FSH combined with equine chorionic gonadotropin (eCG) upregulates mRNA encoding proteins involved with LH receptor intracellular signaling in granulosa cells from Nelore cows
(2014)
The LH plays a key role in controlling physiological processes in the ovary acting via LH receptor (LHR). In general, the effects of LHR on the regulation of granulosa cell differentiation are mediated mainly via the ...
Effect of superstimulation on the expression of microRNAs and genes involved in steroidogenesis and ovulation in Nelore cows
(2018-04-01)
To better understand the impact of ovarian superstimulation on bovine follicular microenvironment, Nelore cows (Bos taurus indicus) were subjected to ovarian superstimulation with follicle stimulating hormone (FSH, n = 10; ...
Effect of ovarian superstimulation on COC collection and maturation in alpacas
(ELSEVIER SCIENCE BV, 2007)
Development of a GnRH-PGF2α based synchronization and superstimulation protocol for fixed-time mating in llama embryo donors
(Frontiers Media S.A., 2020-11-12)
The aim of the present study was to evaluate the application of a GnRH-PGF2α based synchronization and superstimulation protocol for fixed-time natural mating in llama embryo donors. All females (n = 8) received 8 μg IM ...
Lipid profiles of follicular fluid from cows submitted to ovarian superstimulation
(Elsevier B.V., 2017-05-01)
Ovarian superstimulation with exogenous gonadotropins has been extensively used to produce in vivo derived embryos for embryo transfer in cattle. This process modifies the antral follicle microenvironment and affects oocyte ...
