Abstract

Polyzoospermia has been repeatedly associated with reduced fertility and increased rates of spontaneous abortion. We examined semen samples of 1374 infertile men and found an incidence of 4.2% of semen with a sperm density exceeding 250 X 10(6) sperm cells/ml. The spontaneous pregnancy rate in 30 evaluated couples in whom the male partner presented with polyzoospermia was 38.7% and the spontaneous abortion rate was 25%. Sperm penetration tests revealed normal mucus-penetrating ability in 29 of 30 men examined. The reason for reduced reproductive performance in polyzoospermic men does not seem to be disturbed sperm mucus interaction.

摘要

多精子症一直反复与生育力降低和自然流产率增加相关。我们检查了1374名不育男性的精液样本，发现精子密度超过250×10⁶个精子细胞/毫升的精液发生率为4.2%。在30对评估的夫妇中，男性伴侣患有多精子症，其自然妊娠率为38.7%，自然流产率为25%。精子穿透试验显示，在接受检查的30名男性中，有29名的精子具有正常的穿透黏液能力。多精子症男性生殖性能降低的原因似乎不是精子与黏液的相互作用受到干扰。
