Incidences of male factor sub-fertility on the basis of semen analysis have been reported. 275 semen samples were analyzed using standard laboratory techniques as per WHO laboratory manual. Of the total test samples, 158 were found normal and 117 were graded as abnormal. This shows a male factor subfertility of 42.55%. Among the 117 semen samples, highest incidence of cases was due to azoospermia (24.78%) and lowest with oligoteratozoospermia (3.40%). Cases having oligoteratoasthenozoospermia were 17.18%. On analyzing the data, 15% of normal and 18.8% abnormal semen were found infected. This shows that infection does not play any significant role in changing the quality of the semen. The increase in the abnormality of the semen (i.e. 42.55%) is an alarming condition which could lead to male factor infertility.
