ABSTRACT

The study of male factor infertility has been one of the least clear and hardest to protocol. Besides, seminal parameters have been subject to discussion and their impact on fertility still is controversial. Classifying the millions of spermatozoids that are daily produced by a male had been a hard and continuous work until 1980, when the World Health Organization first published the “Laboratory Manual for the Examination and Processing of Human Semen”. This manual establishes and standardizes the proceedings and results for clinical laboratories studies and also serves for diagnostic purposes. It has been updated and widely revised by a group of experts in 1987, 1992, 1999 and 2010. The last edition (5th) has several changes in the proceedings and the evaluation of their outcomes, and it has been based on data obtained from males whose partners had successfully achieved a pregnancy prior to the study.
