Ureaplasma parvum and Ureaplasma urealyticum are detected in semen after washing before assisted reproductive technology procedures
Knox, Christine L., Allan, John A., Allan, Janet M., Edirisinghe, W. Rohini, Stenzel, Deborah J., Lawrence, Felicity A., Purdie, David M., & Timms, Peter (2003) Ureaplasma parvum and Ureaplasma urealyticum are detected in semen after washing before assisted reproductive technology procedures. Fertility and Sterility, 80(4), pp. 921-929.
Objective: To investigate the prevalence of ureaplasmas in semen and washed semen and to explore their effect on semen andrology variables.
Design: Prospective study.
Setting: In vitro fertilization (IVF) unit of a private hospital.
Patient(s): Three hundred forty-three men participating in an assisted reproductive technology (ART) treatment cycle.
Main outcome measure(s) The prevalence of ureaplasmas in semen and washed semen tested by culture, polymerase chain reaction assays, and indirect immunofluorescent antibody assays.
Result(s): Ureaplasmas were detected in 73 of 343 (22%) semen samples and 29 of 343 (8.5%) washed semen samples. Ureaplasmas adherent to the surface of spermatozoa were demonstrated by indirect immunofluorescent antibody testing. Ureplasma parvum serovar 6 (36.6%) and U. urealyticum (30%) were the most prevalent isolates in washed semen. A comparison of the semen andrology variables of washed semen ureaplasma positive and negative groups demonstrated a lower proportion of nonmotile sperm in men ureaplasma positive for washed semen.
Conclusion(s): Ureaplasmas are not always removed from semen by a standard ART washing procedure and can remain adherent to the surface of spermatozoa.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
