Effect of freezing and thawing rates on sperm motility in Bocachico Prochilodus magdalenae (Pisces, Characiformes) Efecto de la congelación y descongelación sobre movilidad espermática en Bocachico Prochilodus magdalenae (Pisces, Characiformes)
TL;DR: In this paper, four interactional treatments were implemented between two freezing and two thawing (rapid and slow) curves, in a 2x2 factorial as follows: rapid freezing-rapid thwawing, rapid freezingslow thwing, slow freezingrapid fastwaving, and slow freezing-slow thowing, and each of them had a significant effect on motility.
Journal ArticleDOI
Virilization of the female spotted hyena cannot be explained by alterations in the amino acid sequence of the androgen receptor (AR).
TL;DR: The findings suggest that the structural changes in the AR do not account for the abnormal virilization in the female spotted hyena, and serve to focus attention on processes proximal (an abnormality of hormone formation in situ) or distal (activation by other mechanisms of processes normally regulated by androgen) to the AR as the cause of thevirilization.
Journal ArticleDOI
Experimental drought affects the reproduction of the brooding clausiliid alinda biplicata (montagu, 1803)
TL;DR: The effect of drought on the reproduction of Alinda biplicata was to delay reproduction, but not to cause adult mortality or significant losses in the uterus.
Journal ArticleDOI
Nursing one litter of Mongolian gerbils while pregnant with another: effects on daughters' mate attachment and fecundity
TL;DR: The results suggest that the reproductive phenotype of females can be profoundly affected by naturally occurring variation in access to maternal resources that results from conflict between successive progeny in mammalian species where dams are sometimes both pregnant and nursing and sometimes neither pregnant with nor nursing one litter while rearing another.
Journal ArticleDOI
Retinoic acid retards fetal and hindlimb skeletal development asymmetrically in a retinoic acid-induced clubfoot model
TL;DR: Prenatal RA exposure had retardation effects on the developing hindlimb skeleton that was independent of those on the overall fetal growth, and different regions of the limb bud responded differently to the teratogenic effects of RA.

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.
