Anyone can have alopecia areata. It often begins in childhood. You have a slightly higher risk of having alopecia areata if a close family member has it. Your risk is even greater if your family member lost his or her first patch of hair before age 30.
A transurethral resection of the prostate (TURP) is surgery to remove parts of the prostate gland through the penis. No incisions are needed. The surgeon reaches the prostate by putting an instrument into the end of the penis and through the urethra. This instrument, called a resectoscope, is about 12 inches long and .5 inch in diameter.
In most cases, a TURP is a safe procedure and the risk of serious complications occurring during surgery is very small. However, many men who have had a TURP lose the ability to ejaculate semen during sex or masturbation, although they still have the physical pleasure associated with ejaculation (the climax). This is known as retrograde ejaculation, and can occur in as many as 9 out of 10 cases.
