When the “blades” become blunt.

All we know that any mechanism wears out with the years. The human body isn't an exception. But, maybe, just few of us know the very changes happen to our organs. Not so long ago scientists paid their attention to the “way of life” of the most discussed man's body part. There's nothing to be afraid of: we're not going to talk about such things as erectile dysfunction or low testosterone level. There are things much more interesting than those “nightmares.”

Recent studies revealed changes man's penis undergoes during the period of “adult life” (staring from 30 for most guys) to the old age. Ok, men, are you ready to hear it? Well, let's start then:

1. Size. It could considerably change it's value. Ira Sharlip, clinical professor of urology at the University of California in San Francisco explains: "A large prepubic fat pad makes the penile shaft look shorter."

2. Appearance. The reduced blood flow causes gradual loss of color of glans. In addition, pubic hair get thin. "As testosterone wanes, the penis gradually reverts to its prepubertal, mostly hairless, state," comments says Irwin Goldstein, director of sexual medicine at Alvarado Hospital in San Diego.

3. Curvature. The unevenly accumulated penile scar tissue can result the curvature of penis. le age. However, a good surgeon will help to “save the situation.”

4. Sensitivity. The main thing here is: penis loses it's sensitivity over time. This could cause some difficulties with having orgasm. However: "The most important ingredient for a satisfying sex life is the ability to satisfy your partner, and that doesn't require peak sexual performance or a big penis. As long as a man's partner enjoys sexual intercourse, he feels like a god," states Goldstein.
