Evaluation of GnRH treatment 12 days after AI in the reproductive performance of dairy cows
TL;DR: Administration of a GnRH agonist on Day 12 after AI did not improve reproductive performance in dairy cows, however, the approach may be used for the field evaluation of different treatment protocols.
Journal ArticleDOI
From insect ovaries to sheep red blood cells : A tale of two hormones
TL;DR: Evidence that juvenile hormone acts on the follicular epithelium of the ovary through a membrane receptor to control access of yolk proteins to the oocytes suggests that the hormones arose as biotic signals, originally using existing CO(2) receptors.
Journal Article
Gonadal Structure and Gametogenesis of Trigla lyra (Pisces: Triglidae)
TL;DR: The gonadal structure and development stages of germ cells of Trigla lyra and the presence of postovulatory follicles in ovaries which still contain developing vitellogenic oocytes suggest that T lyra spawns on multiple occasions over a relatively prolonged period of time.
Journal ArticleDOI
Differential involvement of rat sperm choline glycerophospholipids and sphingomyelin in capacitation and the acrosomal reaction
Samanta Romina Zanetti,Maria de Los Angeles Monclus,Daniel E. Rensetti,Miguel W. Fornés,Marta I. Aveldaño +4 more
TL;DR: The massive cholesterol and phospholipid loss from the gametes during capacitation is thus associated with protein phosphorylation, a function that has been located to the sperm tail and could be implicated in sperm-oocyte interactions.
Journal ArticleDOI
Reproductive seasonality in the mare: neuroendocrine basis and pharmacologic control
Gary L. Williams,Gary L. Williams,Jennifer F. Thorson,Jennifer F. Thorson,Ligia D. Prezotto,Ligia D. Prezotto,I. C. Velez,I. C. Velez,Rodolfo C. Cardoso,Rodolfo C. Cardoso,Marcel Amstalden +10 more
TL;DR: The continuous infusion of native GnRH is both reliable and efficient for accelerating reproductive transition and is uniquely applicable to the horse, despite continuing deficits in some fundamental areas.

Seasonal breeding:nature's contraceptive.
G A Lincoln,Roger V. Short +1 more
TL;DR: The seasonal cycle highlights the seasonal changes in daylight length, rutting behavior, testicular diameter, sexual skin flush, and concentrations of plasma follicle-stimulating hormone, prolactin, and testosterone in a group of rams throughout the year.
Journal ArticleDOI
The physiological responses of anovulatory ewes to the introduction of rams: a review.
TL;DR: Ewes of many breeds can be stimulated to ovulate by the reintroduction of rams and appear to be effected both through a delay in the onset of the LH surge and through a direct action of progesterone on the ovary.
Journal ArticleDOI
Factors affecting the secretion of luteinizing hormone in the ewe.
TL;DR: LH is secreted as discrete pulses throughout all stages of the reproductive cycle of the ewe, including pre‐pubertal, seasonal and lactational anoestrus, and the luteal and follicular phases of the oestrous cycle.
Nutritional influences on reproduction in mature male sheep and goats
TL;DR: In this article, it was shown that nutritional signals exert powerful effects on the reproductive system of mature male ruminants, and the responses are partly independent of changes in gonadotrophin secretion.
