Seminal Parameters: Current Status

Abstract

The World Health Organization laboratory manual for the examination of human semen and sperm–cervical mucus interaction was first published in 1980, in response to a growing need for the standardization of procedures for the examination of human semen. It has since been updated three times, and translated into a number of languages. Over the past 30 years, the manual has been recognized as providing global standards and has been used extensively by research and clinical laboratories throughout the world. Classically, infertility is defined as the inability to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse. The incidence of male infertility is the same woman, i.e. around 40%. The other 20% apply to both. On the other hand, the chance of a couple to become pregnant is not high. Is around 15-17% per month [1].
