Mechanisms of sexual selection: Sexual swellings and estrogen concentrations as fertility indicators and cues for male consort decisions in wild baboons
TL;DR: It was found that sexual swellings reflected conception probability within and among cycles, and Alpha males are the least constrained in their mating behavior and can best take advantage of these cues to mate selectively.
Journal ArticleDOI
Prenatal Exposure to Low Doses of Bisphenol A Alters the Periductal Stroma and Glandular Cell Function in the Rat Ventral Prostate
Jorge G. Ramos,Jorgelina Varayoud,Carlos Sonnenschein,Ana M. Soto,Mónica M. Muñoz de Toro,Enrique H. Luque +5 more
TL;DR: It is suggested that prenatal exposure to BPA altered the differentiation pattern of periductal stromal cells of the ventral prostate, significant in light of the data on human prostate cancers where alterations in the stroma compartment may enhance the invasive and/or malignant potential of the nascent tumor.
Journal ArticleDOI
Reptilian viviparity: past research, future directions, and appropriate models.
TL;DR: Future studies and analyses should abandon assumptions of universal physiological mechanisms and a single historical sequence, in favor of the documentation of diversity in phylogenetic and quantitative terms.
Journal ArticleDOI
Anchoring Junctions As Drug Targets: Role in Contraceptive Development
TL;DR: A novel approach with the aim of developing a nonhormonal male contraceptive for future human use is discussed, one that involves perturbing adhesion between Sertoli and germ cells in the testis.
Book ChapterDOI
Comparative developmental biology of the mammalian uterus.
TL;DR: Comparison biology of the mechanisms regulating uterine development in other species may be useful to identify candidate genes and pathways to understand congenital abnormalities in humans and domestic animals.

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.
