Attitudes

about the existence of and treatments for the age-

male sexuality have been slowly chang-

some time, but the FDA's approval of Pfizer Labs' new drug Viagra" (known generically as sildenafil citrate) on March 28, 1998 must stand out as a major milestone. We say this, not because FDA approval is all that monumental or because Viagra* is such a breakthrough drug. As we will show in the pages that follow, Viagra'- may have its place, but it leaves much to be desired, and there are numerous natural alternatives that may be just as good and far safer. March 28, 1998 marked a turning point because that was the day that impotence, for ages the darkest and ing for

The word "menopause" refers to the end of menstruation, a uniquely female condition.

Eunuchs also functioned as chamberlains to these powerful men. A few eunuchs even used their position of trust and closeness to powerful men to gather great power for themselves.

Between 1624 and 1627, he controlled the palace with a division of eunuch troops, while ruthlessly exploiting and terrorizing the population. When the emperor died unexpectedly in 1627, Wei quickly fell from power and ended up hanging himself to avoid prosecution.
