A male client asks, "Why do I have to use another contraceptive? I had a vasectomy last week." The best response is:
a. "A vasectomy is only 85% effective."
b. "A vasectomy is not effective in all men."
c. "Semen may contain sperm for 6 months following a vasectomy."
d. "Complete sterilization doesn't occur until all sperm have left the system."
ANS: D
It may take a month or longer for all sperm to be removed from the system. During that time, an additional method of contraception must be used. A vasectomy is more than 85% effective. Vasectomies have a high success rate but it may take 1 month for all the sperm to be removed from the system. After 1 month, all the sperm have usually been removed from the system.
