The Fallopian Tube of the Sheep II. The Influence of Progesterone and Oestrogen on the Secretory Activities of the Fallopian Tube

Abstract

Secretion of fluid by the fallopian tubes was examined in normal ewes during their sexually active period and in ovariectomized ewes which were treated with progesterone and oestradiol benzoate. The normal ewes showed a cyclical variation in fluid secretion with a peak output of 0·98 ml/day in oestrus dropping to 0·37 ml/day in dioestrus. In ovariectomized animals oestradiol benzoate produced a cyclical variation similar to that seen in the normal ewe. The effect of progesterone was to shorten the response to oestrogen from 6 to 4 days. Progesterone given alone did not raise fluid secretion above that observed in untreated ovariectomized ewes.
