Characterization of Hyperactivated Motility by Human Spermatozoa During Capacitation: Comparison of Fertile and Oligozoospermic Sperm Populations
Abstract
Suspensions of capacitating human spermatozoa were analyzed for potential hyperactivated movements using videomicrographic methods. Analysis was carried out on aliquots of 22 sperm suspensions, which were proved fertile several hours later during human in vitro fertilization. After approximately 3 h of capacitation, 22.1% of the fertile spermatozoa displayed motility patterns designated as hyperactivated. Over 80% of these hyperactivated spermatozoa moved with a wide-amplitude, two-dimensional whiplash pattern, displaying marked lateral displacement of the head. Only 8.4% of capacitating spermatozoa from oligozoospermic patients showed these hyperactivated movements. The incidence of hyperactivated movements by fertile and oligozoospermic spermatozoa could be significantly increased after exposure to various motility stimulants. The clinical significance of hyperactivation as a functional assay of fertilizing capacity is discussed.

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.
