Fertility problems in men are defined when after 1 year of sexual activity without contraception, impregnation of a female does not occur. It is further defined that the female partner has a normal anatomical and physiological reproductive tract. There is a 10% infertility rate in all couples. Fertility in men depends on the following physical systems to be working: production of normal quantities of healthy sperm, ability to achieve an erection and to ejaculate sperm into the vagina during sexual intercourse.
Causes of Fertility Problems In Men
Fertility problems in men arise from many causes. They include anatomical abnormalities of the penis or testicles, including undescended testicles. Excessive alcohol intake can affect male fertility. Urinary tract infections can prevent male fertility. Hormonal disturbances, such as decreased testosterone levels, can produce impotence. Mumps and other infectious agents can affect the testicles. Some drugs, such as antihypertensives, cytotoxic drugs, male hormones and MAO inhibitors can impair fertility in men. Sexually transmitted disease, especially syphilis and non-specific urethritis, that causes scarring, can prevent normal dissemination of sperm. Injury to the genitals and varicose veins in the testicles can all prevent the normal production of sperm or their transport. Psychological reasons, such as fear of infertility, may be associated with male infertility. Overheating of the testicles caused by vigorous, repetitive exercise or underwear that is too tight and holds the testicles too close to the body, can lead to elevated temperatures in the testicles with decreased viability of sperm. Intercourse problems, such as premature withdrawal, poor timing with menses, too infrequent, and ejaculatory dysfunction all can interfere with male fertility.
