Abstract

Objective To investigate, in men presenting with recurrent pregnancy loss (RPL), the prevalence of sperm autosome and sex chromosome aneuploidy.Design Retrospective study.Setting Male infertility clinic.Patient(s) A total of 140 men with RPL provided semen samples, and five normozoospermic controls provided 140 semen samples for comparison. Recurrent pregnancy loss, documented in the female partners, was defined as a prior miscarriage and/or recurrent IVF/intracytoplasmic sperm injection failure.Intervention(s) Fluorescence in situ hybridization (FISH) was used to detect numerical abnormalities in sex chromosomes (X, Y) and autosomes (13, 18, 21) in ejaculated sperm.Main outcome measure(s) Sperm aneuploidy in men with RPL and normozoospermic controls.Result(s) Men with RPL had a greater percentage of sperm aneuploidy within the sex chromosomes and chromosomes 18 and 13/21 (1.04% vs. 0.38%; 0.18% vs. 0.03%; 0.26% vs. 0.08%). In total, 40% of men with normal sperm density and motility had abnormal sperm aneuploidy in all the chromosomes analyzed. Men with abnormal sperm density and motility had a higher proportion of sperm sex chromosome aneuploidy than men with normal density/motility (62% vs. 45%). Men with normal strict morphology (>4%) had lower rates of sex chromosome and sperm aneuploidy than men with abnormal strict morphology (28% vs. 57%). There was no association between sperm DNA fragmentation and sperm aneuploidy.Conclusion(s) Men with RPL have increased sperm aneuploidy compared with controls. A total of 40% of men with RPL and normal sperm density/motility had abnormal sperm aneuploidy. Men with oligoasthenozoospermia and abnormal strict morphology had a greater percentage of sperm aneuploidy compared with men with normal semen parameters.

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.
