Background:
Raloxifene is a benzothiophene, selective estrogen receptor modulator with estrogen-agonist effects in the skeleton and the cardiovascular system but estrogen-antagonist effects in the uterus and the mammary gland. This compound was first approved in different countries for the prevention and treatment of osteoporosis.
Objective/Methods:
We performed a literature search to review available preclinical and clinical data that has led to the recent FDA approval of raloxifene as a chemopreventive agent for breast cancer in postmenopausal women.
Results/Conclusions:
Different placebo-controlled trials indicated that raloxifene is effective in reducing invasive breast cancer risk in postmenopausal women. In a recent comparative study, a similar efficacy between raloxifene and tamoxifen for breast cancer prevention was demonstrated, but raloxifene showed a more favorable safety profile.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
