The relationship between daily sperm productions (DSP) and daily sperm output (DSO) was determined in eleven stallions. The DSO was determined by collecting single ejaculates, with an artificial vagina, at 24-hr intervals. The stallions were killed 24 hr after the last collection and the DSP was determined by quantitative testicular histology. The mean DSP was 8-0 X 10(9) (S.E. +/- 0-4 X 10(9), and the mean DSO was 7-0 X 10(9) (S.E. +/- 0-4 X 10(9)). It was estimated that 87% of the spermatozoa produced by the testes were harvested. The correlation between DSP and DSO was 0-80 (P less than 0-01), and between DSP and testis weight was 0-77 (P less than 0-01).
在11匹种马中确定了每日精子生成量（DSP）与每日精子排出量（DSO）之间的关系。通过每隔24小时用人工阴道采集一次单次射精来确定DSO。在最后一次采集后24小时处死种马，并通过定量睾丸组织学确定DSP。平均DSP为8.0×10⁹（标准误±0.4×10⁹），平均DSO为7.0×10⁹（标准误±0.4×10⁹）。据估计，睾丸产生的精子有87%被采集到。DSP与DSO之间的相关性为0.80（P＜0.01），DSP与睾丸重量之间的相关性为0.77（P＜0.01）。
