Abstract

We have used two approaches to test the ability of the human zona pellucida to induce acrosome reactions in human sperm. First, nonviable human oocytes were incubated for 1 min in a suspension of capacitated sperm (of which fewer than 5% were acrosome-reacted) to allow binding of about 200 sperm per oocyte. Some of the oocytes were fixed immediately, and the remainder were fixed after a further 1-h incubation without free-swimming sperm. As determined by light microscopy, sperm on the zona were only 3 +/- 2% (avg. +/- SD) acrosome-reacted at 1 min, and the incidence increased to 46 +/- 15% during the next hour. Electron microscopy confirmed that most sperm on the zona at 1 min were acrosome-intact. A few sperm were in an early stage of the acrosome reaction. Acrosome reactions occurring on the zona during the subsequent hour appeared to be morphologically normal. Second, treatment of sperm in suspension with acid-disaggregated zonae (2 to 4 zonae/microliter) increased the incidence of acrosome-reacted sperm from 3 +/- 1% to 24 +/- 4%. We conclude that the human zona pellucida, or material intimately associated with it, can induce acrosome reactions in human sperm.

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.
