Effects of oral contraceptives or a gonadotropin-releasing hormone agonist on ovarian carcinogenesis in genetically engineered mice.

6 Sep 2009 Although epidemiologic evidence for the ability of combined oral contraception (OC) to reduce the risk of ovarian cancer (OvCa) is convincing, the biological mechanisms underlying this effect are largely unknown. We conducted the present study to ... Read more...

Neonatal estrogenic effects upon the male rat pituitary: early gonadotrophin attenuation precedes long-term recovery.

28 Jun 2009 Neonatal exposure to potent estrogenic compounds can affect multiple components of the male reproductive system causing impaired development of the epithelium and overgrowth of stromal tissue in the epididymis, vas deferens, seminal vesicles, and ... Read more...

Androgens and Alzheimer's disease.

30 May 2009 PURPOSE OF REVIEW: To discuss the relationship between androgens, cognition and Alzheimer's disease. RECENT FINDINGS: It has been found that low circulating levels of androgens are a risk factor for Alzheimer's disease. Decreased circulating ... Read more...

Technical information about 'Gonadotropins'

Definition: Hormones that stimulate gonadal functions such as GAMETOGENESIS and sex steroid hormone production in the OVARY and the TESTIS. Major gonadotropins are glycoproteins produced primarily by the adenohypophysis (GONADOTROPINS, PITUITARY) and the placenta (CHORIONIC GONADOTROPIN). In some species, pituitary PROLACTIN and PLACENTAL LACTOGEN exert some luteotropic activities.
