Infertility refers to a condition where there is no pregnancy, even after one year of regular sexual intercourse. It covers a broad spectrum of conditions which can be minor or serious. Infertility related to men is initially investigated usually with a physical examination along with a discussion about past and present medical history. A physical exam determines the general health of both partners. The doctor will pay special attention to the outer sex organs as well as characteristics such as breast development and body hair in both partners to check for structural abnormalities or signs of possible hormone problems. The medical history gathers information that may suggest causes for infertility in each of the partners. Issues that will be discussed during the medical history apply to both the man and the woman.
The most common cause of male infertility is low sperm count or absence of sperm in the semen.
Causes of low sperm count may include
• Hormonal problems in the testicles or pituitary gland.
• Genetic factors.
• Testicular injury, infection or failure.
• Drug use.
Environmental factors including
chemical pollution and exposure to radiation. Medical conditions such as a
varicocele in the testicles, blocked ejaculation due to a surgical vasectomy,
absence or blockage of a vas deferens due to birth defect or infections (The vas
deferens is a narrow, muscular tube that connects the testicles to the prostate
gland), retrograde ejaculation (the ejaculation of semen into the bladder rather
than out through the penis), Chromosomal problems.
Problem caused by the immune system after an infection, vasectomy or injury to the testicles. The man may develop, an auto-immune response in which his immune system treats his sperm as 'foreign' and produce antibodies against them.
Testing to determine the cause of infertility in men
There are number of test to establish the cause of infertility. The first tests are done to check the man's semen (Semen Analysis). A sample of semen may be analyzed to know the sperm count and quality of sperm. The Sperm mucus Penetration Test and the Sperm Penetration Assay (SPA) are used to test the sperm's function. Scanning of the reproductive organs to see if there is a physical abnormalities and blood or urine test to check the hormone levels are also done.
