Changes in the temperature, pH, and partial pressure of oxygen (PO2) in the cervical canal and cavum uteri were measured in women with or without an intrauterine device and in the uteri of rats throughout the cycle. Only the PO2 exhibited significant variations, rising during the ovulatory phase in both cervices of women and uteri in rats. It is speculated that the rise in PO2 is related to the function of these organs as reservoirs for spermatozoa.
在有或没有宫内节育器的女性以及整个周期中大鼠的子宫内，测量了宫颈管和子宫腔内的温度、pH值以及氧分压（PO2）的变化。只有PO2表现出显著变化，在女性的两个宫颈以及大鼠的子宫的排卵期均升高。据推测，PO2的升高与这些器官作为精子储存库的功能有关。
