Ureaplasma urealyticum (T. mycoplasma) and male infertility in topical countries.

In view of the potential role of ureaplasma urealyticum in reproductive failure, sample of semen from 100 Nigerian males was cultured in oxoid mycoplasma broth. In 39% of the patients, Uraeplasma uraelyticum was cultured. Of those with positive culture, 92.3% were infertile patients. Five subfertile males achieved pregnancy in their partners after eradication of the ureaplasma urealyticum by a course of tetracycline.
