Tubal and uterine motility in vivo in the rhesus monkey.
Previous data indicate that there are definite qualitative and quantitative patterns of tubal activity during the various phases of the menstrual cycle. In the present investigation, the simultaneous activity of the uterus and Fallopian tube was recorded in vivo in mature rhesus monkeys throughout the menstrual cycle. The observations indicate that there are characteristic patterns of both tubal and uterine activity, depending on the various phases of the menstrual cycle. The simultaneous recordings of tubal and uterine activity show that the tubal and uterine contractions are not synchronous or even have a similar pattern. The presence of a transmetrial catheter for recording of uterine activity seems to modify the patterns of tubal activity, particularly during the ovulatory phase. It seems possible that the transmetrial catheter has a similar effect as an intrauterine contraceptive device in this species.
