Nonsteroid Ovarian Hormones

Steroid Hormones and Ovarian Cancer

Globally, ovarian cancer is the 6th most common malignancy in developed countries, responsible for 100,300 new cases and 64,500 deaths annually (Jemal et al., 2011). Approximately 90% of ovarian cancers arise within the ovarian surface epithelium (OSE) or the fallopian tube surface epithelium; the remainder of ovarian malignancies develops from other ovarian tissues (sex cord-stromal, germ cell...

//steroid Hormones and Regulation of Ovarian Function

A family of C29 4,4-dimethylsterol intermediates in the cholesterol biosynthetic pathway from lanosterol has been found to induce oocytes to resume meiosis.[248] One of these sterols, 4,4-dimethyl-5α-cholest-8,14,24-triene-3β-ol, was extracted from human follicular fluid and named follicular fluid meiosis–activating substance (FF-MAS). A related compound, 4,4-dimethyl-5α-cholest-8,24-diene-3β-o...

Role of ovarian hormones in hoarding pattern.

Hoarding pattern studied in 28 adult female albino rats indicated cyclic changes in hoarding corresponding to alterations in estrus cycle. It was observed that the hoarding score was maximum at proestrus and the least at diestrus. Animals ovariectomised at proestrus maintained higher hoarding score and those ovariectomised at diestrus stablised on lower hoarding score. Progesterone administrati...

Ovarian Hormones, Adhd, Risk-taking, & Impulsivity

Selected biochemical actions of ovarian hormones.

This review is concerned with a general discussion of the actions of ovarian hormones, including relaxin, a polypeptide hormone, and estrogens and progestogens, which are two types of steroid hormones. Particular emphasis is placed on describing the sites of action and target organ responses induced by the two steroid hormones. A detailed description of estrogen activity in reproductive tract t...
