Male subfertility

Abstract

Infertility is a condition that involves a man and a woman attempting unsuccessfully to conceive a child. A working definition of the problem is necessary to provide criteria for initiating an evaluation. As a practical guide, infertility is present when a woman fails to conceive after one year of regular, sufficiently frequent, unprotected intercourse. Since the male or female or both partners may have specific factors causing the infertility, both should be examined initially. Male subfertility accounts for 45% of all infertile marriages and contributes to a further 10% when both partners are subfertile.
