[Experimental reflex ovulation].

The effect of mating on ovulation and follicular maturation along the ovarian cycles were studied in the rat. The number and size of follicles and the number of ovules in the Fallopian tube were estimated. When the copulation took place between 16 hour of the diestrus and 16 hour of the proestrus phase, a significant increase in the number of large follicles and total follicles was found on the other hand, between 10 hour of the proestrus and 10 hour of the estrus phase, the number of ovules, small follicles and total follicles increased significantly. Thus, the copulation appeared to facilitate the follicular development and ovulation.
