The conventional sperm characteristics of density (millions per milliliter) and motility, scored in a semi-subjective way, were correlated with results of an on-going in vitro fertilization and embryo transfer program. No male infertility patients were included in this study. Individual characteristics of the "successful" ejaculates are described. Sperm densities in the original ejaculate of more than 10 X 10(6) spermatozoa/ml did not significantly improve outcome (P less than 0.01). In contrast, sperm motility seemed to play the most important role, since most pregnancies (12/14) occurred using sperm samples with greater than or equal to 60% total motility (P less than 0.001). The incidence of multipronuclear fertilization is also described and discussed. These data, which were collected during 1984 in the in vitro fertilization unit of Professor R. Schoysman and coworkers (Vilvoorde, Brussels), may help to make fertilization in vitro and embryo transfer a viable method in cases of mild male subfertility, and to provide guidance in preparing some couples for the combined use of husband and donor semen if a sufficient number of oocytes are obtained.
以半主观方式评分的传统精子密度（每毫升百万个）和活力特征，与正在进行的体外受精和胚胎移植项目的结果相关。本研究未纳入男性不育患者。描述了“成功”射精的个体特征。原始射精中精子密度超过10×10⁶个精子/毫升并不能显著改善结果（P<0.01）。相比之下，精子活力似乎起着最重要的作用，因为大多数妊娠（12/14）发生在总活力大于或等于60%的精子样本中（P<0.001）。还描述并讨论了多原核受精的发生率。这些数据于1984年在R. Schoysman教授及其同事（布鲁塞尔维尔沃德）的体外受精单元收集，可能有助于使体外受精和胚胎移植成为轻度男性生育力低下病例的可行方法，并在获得足够数量卵母细胞时，为一些夫妇联合使用丈夫和供体精液提供指导。
