How does testosterone deficiency affect both sexes?

Dr. Michael Roizen, MD
Internal Medicine
We all know the role hormones have on gender differences. Testosterone is the substance that gives James Earl Jones his most famous attribute, and estrogen is the substance that gives Dolly Parton hers.

Because hormones do so many different jobs, it should be no surprise that another key reason for sexual dysfunction stems from testosterone deficiency in both men and women.

Even though women produce only small amounts of the male hormone, a woman's testosterone level drives libido. Women lose testosterone as they age, and a large number of drugs-beta blockers and other drugs for hypertension-can negatively affect testosterone.

One of the key physical outcomes for lack of testosterone in women is that it causes a lack of lubrication-and a thinning of the skin around the labia and surrounding areas that makes sex painful.
