本研究描述了在活体条件下测定猪附睾网和附睾部不同部位的pH值。此外，用自动血气分析仪分析了从同一头能育公猪身上采集的完整精液、精液片段、睾丸(输精管传出/网状睾丸)、附睾液和输精液的酸碱状况。在进入附睾管的液体(pH 7.2)和尾部的精子储存区(pH 6.5)之间，发现精子活动的pH梯度。附睾尾(3~4 mm)的碳酸氢根离子浓度明显低于睾丸网液(30 Mm)，这可能与精子静止有关。在射精时，细胞外pH和碳酸氢盐浓度显著增加，富含精囊液的精液中的碳酸氢盐水平是附睾尾部的9-10倍，精子在那里表现出更高的活力。
The present study describes the measurement of pH made in vivo in the rete testis fluid and in different regions of the boar epididymis. Furthermore, samples of whole ejaculates, semen fractions, testicular (ductuli efferents/rete testis), epididymal and deferential fluids collected from the same fertile boars, were analysed for their acid/base status with an automatic blood gas analyser. A pH gradient of activity was found between the fluid entering the ductus epididymis (pH 7.2) and the region of sperm storage at the cauda (pH 6.5). A significantly lower concentration of bicarbonate ion was found in the cauda epididymidis (3-4 mM) compared to rete testis fluid (30 mM), which might be related to the quiescence of the spermatozoa. A significant increase in extracellular pH and bicarbonate concentration occurred at ejaculation, the bicarbonate levels being 9-10-fold higher in the semen fraction rich in seminal vesicle fluid, where sperm showed higher motility, than in the cauda epididymis.
