Male infertility may be caused by pre-testicular causes, tobacco smoking, DNA damage, testicular factors, post-testicular causes and infectious disease causes; all have been implicated to affect semen quality negatively. 12.5% of couples experience infertility in their union elsewhere; in Nigeria, it is 25%. Various reports all over Nigeria implicated between 31.8-83.1% of male partners having poor semen qualities. The WHO guidelines for a comprehensive performance of seminal analysis either with the Manuel method or Computer – Assisted Semen Analysis technique using Sperm Quality Analyzer Visual (SQA-V) machine should be adhered to. As the characteristics of good quality semen are manifest; so are those with poor semen quality. Good quality semen enhances generational posterity. The effects of poor semen quality are enormous as it leads to infertility – generational discontinuity, a cut-down of the family tree. Infertility has been a source of pain, rejection, humiliation, sadness, anxiety and shame to a lot of infertile couples all over but especially in the African sub region.
