Due to its effects on sleep duration and quality, obstructive sleep apnea may result in reduced pituitary hormone production, low testosterone production, and an increased risk of clinical ...
The hook effect refers to the prozone phenomenon, also known as antibody excess, or the postzone phenomenon, also known as antigen excess. It is an immunologic phenomenon whereby the effectiveness of antibodies to form immune complexes can be impaired when concentrations of an antibody or an antigen are very high.
A prolactin modulator is a drug which affects the hypothalamic–pituitary–prolactin axis (HPP axis) by modulating the secretion of the pituitary hormone prolactin from the anterior pituitary gland. Prolactin inhibitors suppress and prolactin releasers induce the secretion of prolactin, respectively. [1] [2]
Thyrotropin-releasing hormone has a stimulatory effect on prolactin release, although prolactin is the only anterior pituitary hormone whose principal control is inhibitory. Several variants and forms are known per species. Many fish have variants prolactin A and prolactin B. Most vertebrates, including humans, also have the closely related ...
Unlike most tropic hormones released by the anterior pituitary gland, prolactin secretion is primarily regulated by hypothalamic inhibition rather than by negative feedback from peripheral hormones. Prolactin also self-regulates through a counter-current flow in the hypophyseal pituitary portal system, which triggers the release of hypothalamic ...
HGH is a hormone that’s naturally produced by your pituitary gland (a small gland nested at the base of the brain), says Dr. Farah Khatoon, DO, MPH, a pediatric endocrinologist with Lurie ...
In posterior pituitary we have hormones that control absorption of water and oxytocin. Anterior hypophysis, neurosecretory cells which release hormones. There is a pituitary portal system, with which the hormones are transported. These hormones are prolactin, growth hormone, TSH, adrenocorticotropic hormone, FSH and LH.
Hormone therapy is typically not recommended for anyone with a personal medical history of breast or uterine cancer, undiagnosed postmenopausal bleeding, active liver disease, heart attack, stroke ...
