A comparison was made between successful (167) and unsuccessful (1322) insemination cycles in order to evaluate the role in conception of different semen characteristics. The most important semen variable was found to be post-thaw motility: the success rate per cycle increased from 7% when post-thaw motility was less than or equal to 40% to 17% when it was greater than or equal to 65%. Multiple inseminations in a cycle increased the success rate primarily when semen quality was poor. The results of this study show how and to what degree efficacy in A.I.D. can be improved by a judicious choice of the semen to be utilized and the number of inseminations to be practiced.
为了评估不同精液特征在受孕中的作用，对成功的（167个）和不成功的（1322个）授精周期进行了比较。发现最重要的精液变量是解冻后活力：当解冻后活力小于或等于40%时，每个周期的成功率为7%，而当解冻后活力大于或等于65%时，成功率提高到17%。在一个周期内进行多次授精主要在精液质量较差时会提高成功率。本研究结果表明，通过明智地选择使用的精液和进行授精的次数，可以在何种程度上以及如何提高人工授精的效果。
