Effects of vitamins C and E on steroidogenic enzymes mRNA expression in polychlorinated biphenyl (Aroclor 1254) exposed adult rat leydig cells
TL;DR: It is suggested that vitamins C and E have ameliorative role against PCBs-induced testicular Leydig cells dysfunction and Aroclor 1254 treatment significantly reduced the serum LH, FSH, testosterone, estradiol and androgen binding protein.
Journal ArticleDOI
Mouse Cysteine-Rich Secretory Protein 4 (CRISP4): A Member of the Crisp Family Exclusively Expressed in the Epididymis in an Androgen-Dependent Manner
TL;DR: A new member of the Crisp protein family, CRISP4, is introduced through in silico analysis of the epididymal expressed sequence tag library deposited in the UniGene database and has a signal sequence suggesting that it is secreted into the epidIDymal lumen and might thus interact with sperm.
Journal ArticleDOI
The role of Wnt signaling members in the uterus and embryo during pre-implantation and implantation.
TL;DR: Specific Wnt signaling pathway members are demonstrated to be critical for endometrial events such as decidualization and endometricrial gland formation in addition to cyclic changes in the endometrium controlled by reproductive hormones.
Journal ArticleDOI
Gonadotropin-releasing hormone and the control of gonadotrope function.
Raymond Counis,Jean-Noël Laverrière,Ghislaine Garrel,Christian Bleux,Joëlle Cohen-Tannoudji,Yannick Lerrant,Marie-Laure Kottler,Solange Magre +7 more
TL;DR: The importance of pulsatility of GnRH action is closely related to, or dependent on, the inability of the GnRH receptor to desensitise, as multiple post-receptor events are crucial for both the regulation/plasticity of gonadotropic function and the maintenance of cell integrity.
Journal ArticleDOI
The metabolic cost of egg production is repeatable.
François Vézina,Tony D. Williams +1 more
TL;DR: It is shown that in captive, controlled conditions, the process of egg formation induces a 22% increase in RMR in female zebra finches Taeniopygia guttata, and that individual variation in both non-breeding and laying RMR is repeatable over periods of at least 8-10 months.

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.
