[A study on Ureaplasma urealyticum and sperm. Comparison of sperm morphology before and after chemotherapy]

Spermiogram (morphology of sperm heads and tails) was evaluated in 21 men visiting our infertility clinic before and after the eradication of genital infection with Ureaplasma urealyticum. The percentage of coiled tails and fuzzy granular tails were decreased after eradication of Ureaplasma but there were no significant changes in the morphologic characteristics of sperm heads. Spermiogram was also analysed in 5 men who were unsuccessfully treated for genital Ureaplasma infection. In this group there were no significant changes in the morphologic characteristics of sperm heads and tails before and after chemotherapy.
