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(More)
The effect of luteinizing hormone (LH) on the respiration of isolated cumulus cell complexes (the oocyte surrounded by cumulus granulosa cells) obtained from immature Sprague-Dawley rats injected with 10 IU pregnant mare's serum gonadotropin on day 30 was investigated. The cell complexes were isolated from preovulatory follicles of rats killed at specific(More)
The concentrations of calcium, magnesium, and zinc were measured by atomic absorption spectrometry. The concentrations of all three cations were found to be strongly correlated with one another and with acidity (pH). Analysis of the relative concentrations in prostatic fluid, split ejaculates, and whole seminal plasma confirmed an almost exclusively(More)
