Occupational Causes Related Male Infertility: A Case Study in Iran

Infertility is defined as an inability of couples to conceive a clinical pregnancy even after the 12 months or more of unprotected intercourse or therapeutic donor insemination (PCASRM, 2013). The man should be evaluated concurrently with the woman, since a male factor is the primary or contributing cause in 40% to 60% of cases (Schlegel, 2009). As the WHO, the prevalence of infertility is 10-15% which means that one out of six couples is suffering from infertility, among which 35-40% of cases are related to male infertility disorders and 20% related to couple factors. Thus, it could be concluded that male causes play an important role in infertility cases (Vaziri et al., 2011)
