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.

D013094 Spermatozoa Mature male germ cells derived from SPERMATIDS. As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.
