Post-ovulatory changes in the water content and inulin space of the rabbit oviduct

Measurement of the water content and inulin space of the tissues of the ampulla, ampullary-isthmic junction and proximal isthmus showed that the loss of oedema was related to the position of the ova, whether this was normal (after hCG), delayed (by oestrogen treatment) or accelerated (by progesterone treatment).
