Ureaplasma urealyticum reduces motility and induces membrane alterations in human spermatozoa
Abstract
The in-vitro effects of several concentrations of Ureaplasma urealyticum on the motility, membrane integrity and morphology of washed spermatozoa from healthy donors were studied. A significant reduction in sperm motility and signs of membrane alteration, directly related to U.urealyticum concentration and contact time were observed. Scanning electron microscopy examination showed masses of U. urealyticum attached to the head and middle piece of some of deformed spermatozoa. It is suggested that U.urealyticum is involved in sperm changes leading to male infertility, particularly when there is heavy U. urealyticum colonization or specific infections with this microorganism.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
