Among the men who volunteered to become semen donors for artificial insemination at the sperm bank of Centre d'Etude et de Conservation du Sperme Humain, Paris-Bicêtre, some were brothers of the infertile men of couples entering the Artificial Insemination with Donor program. Their sperm characteristics, compared with those of other donor candidates, are clearly lower. The difference is significant for count (78.0 versus 102.8, P less than 0.05) and very significant for the percentage of motile spermatozoa (61.5 versus 66.9, P less than 0.01) and for the percentage of normal forms (51.8 versus 62.7, P less than 0.00001). The differences are even more pronounced when the brothers of azoospermic men are considered. The possibility that some cases of infertility could have a genetic origin is discussed.
在巴黎比塞特市人类精子研究与保存中心精子库自愿成为人工授精精液捐赠者的男性中，有些是接受供精人工授精项目夫妇中不育男性的兄弟。与其他候选捐赠者相比，他们的精子特征明显更低。精子计数方面差异显著（78.0对102.8，P<0.05），活动精子百分比差异非常显著（61.5对66.9，P<0.01），正常形态百分比差异也非常显著（51.8对62.7，P<0.00001）。当考虑无精子症男性的兄弟时，差异更为明显。文中讨论了某些不育病例可能存在遗传起源的可能性。
