Semen Quality of Male Partners of Infertile Couples Attending Fertility Clinics in Delta State University Teaching Hospital, Oghara, Delta State, Nigeria

Objective: To determine the proportion of sperm concentration abnormality, teratozoospermia index and the nature of semen abnormal parameters seen among male partners of infertile couples. Materials and methods: This is a retrospective study of male partners of infertile couples who attended fertility clinic at Delta State University Teaching Hospital, Oghara, between 2014 - 2016. Semen samples of 260 male partners were analysed in the andrology laboratory using World Health Organization 2010 criteria for human semen characteristics. Results: A total of 260 male partners were studied and 35% had primary infertility, 65% had secondary infertility and 53% had abnormal sperm concentration. The mean sperm concentration, morphology, progressive motility and teratozoospermia index for normazoospermia group are 72.7 ± 57.8, 4.2 ± 1.6, 61.1 ± 11.8, 1.7 ± 0.2 while the oligozoospermia group has 4.3 ± 4.1, 0.7 ± 1.1, 38.7 ± 7.5, 1.8 ± 0.4 at p - value 0.00. Azoospermia mean and SD for sperm concentration, morphology, progressive motility and teratzoospermia index are absent. Conclusion: There is increased teratozoospermia index in normazoospermia while decreased mean normal sperm morphology and increased teratozoospermia index in oligozoospermia and these are absent in azoospermia subjects thereby causing male infertility which lead to hindrance in attaining pregnancy clinically.
