A 1968 Indian study compared the effect of Norlutin (17-alpha ethynl 19-nor testosterone) and Provera (6-methyl acetoxyprogesterone) suspensions on the uterine motility of virgin rats and mice to the action of natural progesterone and testosterone. The test animals were spayed and 2 weeks later, the rats were injected with 2 mcg of estradiol benzoate daily for 3 consecutive days. The mice received .2 mcg injections. On day 4 the animals were sacrificed and the uterine horns were suspended in a 40 ml organ bath containing Tyrode solution at 32 degrees centigrade and aerated with 5% carbon dioxide in oxygen. Rat uterine movement was recorded isotonically with a linear frontal writing lever while a heart lever was used for mice. The action of the compounds was also tested on oxytocin-induced spasms. Norlutin suspension (1.25-50 mcg/ml) inhibited both amplitude and tone of uterine contraction within 2-10 minutes and lasted more than 1 hour. The uterus failed to respond to oxytocin during peak Norlutin action. A progesterone concentration of 1.25 mcg also produced uterine relaxation but its effect on contractual tone was insignificant. Graded concentrations of Provera and testosterone suspension failed to effect uterine motility in rats and mice.
