QUESTION
The oviducts atrophy and deciliate during?
OPTIONS
(A) Pregnancy
(B) Anoestrus
(C) Hypophysectomy
(D) All of the above
ANSWER
(D) All of the above
EXPLANATION
Oviductal epithelial height and ciliation depend strongly on endocrine stimulation, especially estrogen. Relative epithelial regression and reduced ciliation can occur during progesterone-dominant pregnancy, anestrus, and after hypophysectomy with loss of gonadotropin support. All three therefore fit the traditional comparison, although the degree is species-dependent and pregnancy does not imply complete disappearance of the oviduct's cilia or function.
