ABSTRACT
INTRODUCTION Male factor infertility is defined as a couple’s failure to achieve pregnancy due to problems in the male partner. This condition has emerged as a serious reproductive health issue during the last few decades. As expected, it appeared first in the western societies and attracted immediate attention of both the relevant medical specialists and the public. As new evidence has accumulated from epidemiological data and clinical observations coupled with original information coming from the emergence of assisted reproduction technology (ART) and also from diverse faculties such as genetics, molecular biology, and environmental toxicology, the interest of the medical community increased sharply.
