SUMMARY The electrical activity of the myometrium and the intra-uterine pressure were recorded by means of suction electrodes and intraluminal balloons respectively from anaesthetized, oestrogen-primed, ovariectomized guinea-pigs treated with progesterone (25 mg, s.c. twice, 16 h apart). No loss of intra-uterine pressure occurred after progesterone treatment and electrical activities in the balloon-containing and intact horns were indistinguishable. Furthermore, the concentration of progesterone in the uteri of these animals was 0·32 ± 0·05 (S.E.M.) μg (balloon-containing horn) and 0·43 ± 0·06 μ/g wet tissue (intact horn). These values greatly exceed the levels found in uteri of pregnant animals (0·07 ± 0·03 μ/g wet tissue). Thus the failure of progesterone to reduce myometrial activity in the guinea-pig is real and is not due to interference from the balloon, or to failure of the steroid to reach the uterine muscle or to lack of oestrogen priming.
