In order to investigate the effect of fresh blood serum and normal saline on the motility of ejaculated spermatozoa, semen samples were collected from 7 fertile males, aged 25-39 yrs. Each sample was divided into 5 aliquots: one aliquot remained undiluted, and fresh blood serum from fertile men and normal saline were added to the others to produce 1:1 and 3:1 dilutions. Spermatozoal motility was evaluated objectively, every hour and for 4 h after ejaculation, by the multiple exposure photography method. It was found that serum from fertile men as well as normal saline caused a significant increase of spermatozoal velocity. However, spermatozoal velocity under the influence of serum from fertile men changed with time in a different way than in the undiluted aliquot and those diluted with normal saline. Thus, the beneficial effect of fresh blood serum on spermatozoal velocity, cannot only be attributed to the lowering of seminal viscosity and the reduction of sperm concentration caused by dilution, but to various substances present in blood serum.
为了研究新鲜血清和生理盐水对射出精子活力的影响，从7名年龄在25 - 39岁的可育男性中采集精液样本。每个样本分为5等份：一份不稀释，向其他几份中加入可育男性的新鲜血清和生理盐水，制成1:1和3:1的稀释液。射精后每小时对精子活力进行4小时的客观评估，采用多次曝光摄影法。结果发现，可育男性的血清以及生理盐水均能显著提高精子速度。然而，在可育男性血清影响下的精子速度随时间的变化方式与未稀释样本和用生理盐水稀释的样本不同。因此，新鲜血清对精子速度的有益作用，不仅可归因于稀释导致的精液粘度降低和精子浓度降低，还可归因于血清中存在的各种物质。
