Journal ArticleDOI
Sex and seasonal differences in aggression and steroid secretion in Lemur catta: Are socially dominant females hormonally ‘masculinized’?
TL;DR: Endocrine profiles and social interaction in the ringtailed lemur (Lemur catta), a species characterized by extreme masculinization of the female, are examined to search for a potential source of circulating androgen in adult females and an endocrine correlate of female dominance or its proxy, aggression.
Journal ArticleDOI
Comparison between epididymosomes collected in the intraluminal compartment of the bovine caput and cauda epididymidis.
TL;DR: It is established that epididymosomes from caput and cauda epiddymidis have different protein composition and interact differently with maturing spermatozoa.
Journal ArticleDOI
Regulation of gap junctions and oocyte maturational competence by gonadotropin and insulin-like growth factor-I in ovarian follicles of red seabream.
Reynaldo Patiño,Hirohiko Kagawa +1 more
TL;DR: The present results support the concept that an increase in homologous and heterologous GJ is a general developmental event associated with the acquisition of OMC in teleost ovarian follicles.
Journal ArticleDOI
RFPL4 interacts with oocyte proteins of the ubiquitin-proteasome degradation pathway
TL;DR: The specificity of its expression and these interactions suggest that RFPL4 targets cyclin B1 for proteasomal degradation, a key aspect of oocyte cell cycle control during meiosis and the crucial oocyte-to-embryo transition to mitosis.
Journal ArticleDOI
Control of ovulation in mice by progesterone receptor-regulated gene networks
TL;DR: Functional analyses using gene-knockout mouse models have confirmed that some of these factors play critical roles during ovulation, and helped to understand better the molecular mechanisms that facilitate the release of oocytes from pre-ovulatory follicles.

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.
