Is the inability of a sexually active,  non-contracepting couple to achieve pregnancy in one year ( WHO, 1995 ). Simultaneous examination of the female partner is advisable as it is presumed that each partner carries 50 % of the reasons for the infertility. The prevalent causes of male infertility are varicocoeles, testicular and epididymal abnormalities, prostatic and seminal vesicle problems. However, other conditions predispose to male infertility like undescended testes, mumps orchitis ( testicular enlargement with pain due to mumps ), testicular torsion or twisting, chemotherapy, radiotherapy and endocrine and genetic conditions.
