Well..first thing is to understand something about estrogen |
Estrogen is a generic name for several estrogens. Like Vitamin E, there's no one E, but 6. There are three estrogens collectively known as Estrogen. Estrogen is not strictly a female hormone, nor testosterone a male hormone. Both hormones are produced by males and females. As men get older, their testosterone drops, while the estrogen production remains the same or may even climb a little. This creates an estrogen-to-testosterone ratio in favor of the estrogen, and we see problems with this in the prostate. |
Estrogens Used in The Treatment of Prostate Cancer |
Maarten Bosland of the New York University Medical Center in Tuxedo, says estrogens have been used to treat prostate cancer. However, recent animal studies indicate that these hormones may actually enhance testosterone's threat to the prostate. This estrogen-to-testosterone ratio is thrown off and it now appears this is a major source of prostate cancer in men. We'll discuss this more shortly. |
As the body uses or breaks down estrogen, a number of similar compounds are formed. Working both with animals and with cells grown in test tubes, University of Texas Medical Branch in Galveston, TX., Joachim G. Liehr, a pharmacologist, has discovered some interesting things about estrogen. |
Shuk-mei Ho, an endocrine oncologist at Tufts University in Medford, Mass. says that until now, the search for the mechanisms behind cancer of the prostate has centered on male sex hormones and their effects on genes. However, she and others have demonstrated that hormones can play an unexpected role in the prostate. This area of the male is full of hostile, free-radical-laden substances that hormones that might assist in the understanding of why cancer develops there. |
This association of free radicals with aging in the prostate tissue has spurred the development of several things: |
|
Ho also notes something else happens here in the prostate that causes oxidative damage (free-radical). |

Estrogen-to-testosterone Ratio: Estrogen may or may not be a primary source free radicals in the prostate. Nevertheless, there is a pivotol (vital or critically important) role estrogen plays here. |
The prostate's cells go into a quiescent, nonreproducing phase that lasts for decades. In men, it begins shortly after the organ reaches adult size, around 18-20 or so and continues to about age 50 or 60. Throughout this period, its cells are incessantly-and increasingly-bombarded by free radicals. |
In some way, Shuk-mei Ho believes the increased extrogen-to-testosterone ratio that men develop as they age triggers a resumption of prostate growth. |
