Sperm agglutinins emerging from the reopened part of the vas deferens were found in the seminal fluid of 10 out of 29 men after vasovasostomy. There was a strong association between the presence of these antibodies and the failure to impregnate over a period of 14 to 33 months. Of 20 couples, 11 pregnancies resulted among the 13 women whose men had no sperm agglutinins in the seminal fluid, but only 1 among the 7 whose men had such antibodies, 2p = 0.0044. The presence of sperm agglutinins in the seminal fluid was always associated with their presence in the serum, usually in a higher titre. Preoperative serum levels thus are highly predictive of ability to impregnate after reversal of vasectomy.
在29名接受输精管吻合术的男性中，有10人的精液中发现了来自输精管重新开放部位的精子凝集素。这些抗体的存在与14至33个月内未能受孕之间存在强烈关联。在20对夫妇中，精液中无精子凝集素的13名男性的伴侣中有11人怀孕，但精液中有此类抗体的7名男性的伴侣中只有1人怀孕，P值为0.0044。精液中精子凝集素的存在总是与血清中精子凝集素的存在相关，通常血清中的滴度更高。因此，术前血清水平对输精管复通术后的受孕能力具有高度预测性。
