Background: Pectic acid extracted from plants increases the secretion of prolactin (PRL) when injected intravenously into ewes or fed to rats. Fragments of ewe hypophysis and lactating rabbit mammary gland incubated in vitro in the presence of pectic acid secreted more PRL and caseins compared to the controls. However, it is not known whether pectic acid directly stimulates PRL secretion in pi...

During the period that sexually mature male three-spined sticklebacks display parental fanning behavior, the rate of synthesis and release of the prolactin cells in the hypophysis, as estimated with quantitative electron microscopy, is enhanced considerably. This finding points to involvement of endogenous prolactin in the regulation of parental fanning behavior in this species.

= Abstract = The morphological development of the human hypophysis was studied using 142 developing human hypophyses from 19 embryos and 123 fetuses. The adenohypophysis first developed at 4 weeks of gestational age as an upward growing fold of the primitive oral ectoderm Rathke's pouch. At 7 weeks, the configuration of pars distalis and pars intermedia was formed. The Rathke's pouch lost its c...

Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine-metabolic illness that has alarmingly high rates of infertility and other significant effects on the health women. This review study highlighted Insulin appears to damage every part hypothalamus-hypophysis-ovary axis, insulin resistance in ovarian tissue leads impaired metabolic signalling but intact mitogenic steroidogenic activi...
