Hypophysial Portal

The hypothalamus regulates the secretion of anterior pituitary hormones via release of releasing hormones into the hypophysial portal vasculature. Additional neuromessengers act at the pituitary to modulate responses to the hypothalamic hormones. For example, neuropeptide Y enhances the effect of gonadotropin-releasing hormone and the response to the prolactin-inhibiting hormone dopamine.

Thyrotrophic Hormone

SUMMARY The anterior pituitary content of luteinizing hormone (LH) was greatly reduced 4 hr. after mating in female rabbits; thyrotrophic hormone content was slightly but not significantly reduced. At 24 hr. after mating LH levels were higher than those at 4 hr. but still significantly below control levels; thyrotrophic hormone content was significantly reduced at this time. Since no evidence is available of an increase in thyrotrophic hormone secretion after mating (see Brown-Grant, 1968) it is concluded that the neuroendocrine events concerned in the release of LH in response to coitus in this species also result in a decrease in the synthesis of thyrotrophic hormone.
