Tamoxifen for Low Testosterone in Males My previous article discussed the use of clomiphene for increasing testosterone in hypo-gonadal males. Clomiphene works as an estrogen receptor blocker in the hypothalamus, thus stimulating LH/FSH which then stimulate testicular testosterone production. Tamoxifen Another drug which similarly blocks estrogen receptors is Tamoxifen (tamoxiphen), commonly used in breast cancer survivors to block estrogen receptors. Similar to the use of clomiphene, tamoxiphen has been used to treat low testosterone and low sperm counts (infertility) in males.

Hormonal effects of an antiestrogen, tamoxifen, in normal and oligospermic men. The administration of tamoxifen, 20 mg/day for 10 days, to normal males produced a moderate increase in luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, and estradiol levels, comparable to the effect of 150 mg of clomiphene citrate (Clomid). However, whereas Clomid produced a decrease in the LH response to LH-releasing hormone (LHRH), no such effect was seen after the administration of tamoxifen. order viagra online with prescription About half of male breast cancer patients who take the drug tamoxifen to prevent their disease from returning report side effects such as weight gain and sexual dysfunction, which prompts more than 20 percent of them to discontinue treatment, according to researchers at The University of Texas MD Anderson Cancer Center.

D., associate professor of medicine in MD Anderson's Department of Breast Medical Oncology and senior author of the study. "This research will help doctors and patients better understand the side effects men experience. With this information, patients can make more informed decisions about treatment risks and benefits."Few Empirical Studies of Rare Disease Only about 2,000 men are diagnosed with breast cancer in the United States each year, but its incidence is increasing.

About 2,100 new cases of invasive breast cancer are expected to be diagnosed in men in 2011. A man's lifetime risk of breast cancer is about 1 in 1,000. As in women, most male breast cancer is hormone-receptor-positive. The hormones estrogen and progesterone can potentially support the growth and spread of hormone-receptor-positive breast cancers. So hormonal therapy that blocks the effect of these hormones -- like tamoxifen -- can be a good treatment option for hormone-receptor-positive breast cancer in both men and women. In this study, the researchers looked at the treatment records of 126 men diagnosed with breast cancer between 19. Hormone therapy (sometimes called endocrine therapy) is a way to treat cancer by using hormones or drugs or other treatments that affect hormones. Hormone therapy is a form of systemic therapy, like chemotherapy. It can be used after surgery (adjuvant therapy) to help lower the risk of cancer coming back, or before surgery (neoadjuvant treatment). It is also used to treat cancer that has spread, or cancer that has come back after treatment (recurred). Some breast cancers grow in response to the hormones estrogen or progesterone. Estrogen and progesterone are usually thought of as female hormones, but men have them in their bodies also, just at lower levels. About 9 of 10 breast cancers in men are hormone receptor-positive.
