The oxygen tension in the oviductal fluid of adult female rhesus monkeys was measured by means of miniaturized, flexible, oxygen probes between days 5 and 22 of the menstrual cycle. In the follicular phase, the value was very low, less than 10 Torr. At the time of ovulation to about 5 to 7 days thereafter, the oxygen tension in the tube on the side of ovulation increased within approximately 2 minutes after insertion of the oxygen probe from the low level to the same value as in the blood. In the contralateral oviduct, the oxygen tension remained at less than 10 Torr. These findings suggest that, in the absence of ovulation, the blood-oxygen supply of the oviduct provides the exact oxygen requirement of oviductal tissue, with no excess oxygen available for the tubal fluid. At and shortly after ovulation, the presence of a probe stimulates, by an unknown mechanism, an increase in the oxygen tension in the oviductal fluid which provides an environment sufficiently well-oxygenated for gamete survival, fertilization, and subsequent further development of the embryo. We suggest that the ovum entering the oviduct provides a similar stimulus with a similar result by the same unknown mechanism.
在成年雌性恒河猴月经周期的第5至22天，使用小型化、柔性氧探头测量输卵管液中的氧张力。在卵泡期，该值非常低，低于10托。在排卵时及之后约5至7天，排卵侧输卵管内的氧张力在插入氧探头后约2分钟内从低水平升至与血液中相同的值。在对侧输卵管中，氧张力保持低于10托。这些发现表明，在不排卵的情况下，输卵管的血液供氧提供了输卵管组织确切的氧需求，没有多余的氧供输卵管液使用。在排卵时及排卵后不久，探头的存在通过未知机制刺激输卵管液中氧张力增加，从而为配子存活、受精及随后胚胎的进一步发育提供了充分氧合的环境。我们认为，进入输卵管的卵子通过相同的未知机制提供了类似的刺激并产生类似的结果。
