Glycogen content of rabbit tubular genitalia from mating through implantation

Groups of five rabbits were killed at 0, 2, 4, 7, 10, 24, 48, 98, 168 and 240 hours after mating. The glycogen content of the lower half of the Fallopian tube was greater than in the upper half at each interval. Uterine and Fallopian tube levels of glycogen decreased during the interval from mating to ovulation. Both cervical and vaginal glycogen declined significantly within 24 hours after mating. Decidual uterine areas contained 1.5 and 5.0 times more glycogen on days 7 and 10, respectively, than interdecidual areas. Castrate rabbit Fallopian tube, uterus, cervix and vagina responded with glycogen synthesis to estradiol, but not to progesterone administration.
