title: Semen analysis of infertile Igbo males in Enugu, Eastern Nigeria.
abstract: The semen samples of 1,110 (one thousand, one hundred and ten) Igbo males attending infertility clinic, aged between 30-50 years were collected and analyzed. The specimens were collected and analysed in the microbiology laboratory of the University of Nigeria Teaching Hospital (UNTH) Enugu, Eastern Nigeria. The standard method of masturbation after 3-5 days of prior abstinence from sex before sample collection was applied. The samples were examined for semen volume and microscopically as a wet preparation for sperm motility, morphology and count. The semen volume result showed that 91.07 % were normal. 6.3% sperm samples were motile. In the sperm count, only 7.3% had normal cells, 62.0% showed abnormal morphology. The aetiology of male infertility in the population studied seems to be related to the sperm count, motility and morphology but not volume. Racial factor seems to play no role and it is important to abstain from sexual intercourse some days before collection of semen for analysis.
