**1. Introduction**

With enormous growth of population, India ranks second in world with 1.28 billion. Rather population growth is a major concern, yet infertility is a devastating health problem. According to World Health Organisation (WHO), infertility is the inability of the female partner to attain pregnancy after 1 year or more of the unprotected sex. Infertility affects about 15% of the couple of which half of the reproductive problems are associated with the male counterpart [1]. Many factors, including genetic causes, intoxication, microbial infections in genital tract, changes in lifestyle, stress, and the recent trend of late marriages, contribute to this occurrence. Table 1 highlights infertility due to male genital infections. Despite enormous progress in the under‐ standing of human reproductive physiology, the underlying cause of male infertility remains undefined in about 50% of cases, which are referred to as idiopathic infertility [2, 3].
