A. What is infertility?
• no conception after 12 months of unprotected regular intercourse
• infertility affects about 10% of young adults
• in 40% of the cases, the fertility problem is with males, in 40% of the cases the
fertility problem is with females, and in 20% of the cases it is both or unknown
B. What are some of the possible causes of infertility in males?
• sperm quality (radiation, heat, mumps)
• frequency of ejaculation
• healthy weight (levels of body weight influence levels of hormones circulating in the
blood stream)
• healthy nutrition (certain nutritional deficiencies can effect development of healthy
sperm- they need linoleic acid, vitamin A, vitamin E and zinc)
• alcohol (excessive intake of alcohol has been shown to lower sperm count and may
interfere with the ability to maintain an erection and can mutate the sperm)
• complications of sexually transmitted infections (STIÕs)
C. What are the possible causes of infertility in women?
• PID (Pelvic Inflammatory Disease can cause scarring of the fallopian tubes)
• complications of STIÕs
• endometriosis (uterine tissue growing outside the uterus, often on the ovaries,
fallopian tubes, or in the abdominal cavity)
• cycle irregularities (problems with ovulation, lining thickness, mucous)
• smoking (can interfere with normal egg production and menstrual cycles)
• healthy weight and nutrition (10-15% below normal weight can interfere with a
womanÕs fertility (often affects the menstrual cycle and obesity can lead to decrease
in the frequency of ovulation)
