Male infertility - The other side of the equation.

Abstract

Male infertility can result from anatomical or genetic abnormalities, systemic or neurological diseases, infections, trauma, iatrogenic injury, gonadotoxins and development of sperm antibodies. When a couple fails to achieve pregnancy after 12 months of regular, unprotected sexual intercourse, a screening evaluation of both partners is essential. For the male partner this includes history, physical examination, endocrine assessment and semen analysis. Several lifestyle and environmental factors can have a negative impact on male fertility, and the GP has a pivotal role in educating patients about modifiable factors.
