Hormonal influence on epididymal lipids.

Single dose administration of Prolactin(P), Progesterone (PP) and a combination of both (PPP) affected the epididymal lipids considerably. Caput and Cauda showed differential responses. PP and PPP showed significant alterations in Caput epididymis. However, Prolactin was effective in Cauda epididymis. The importance of these changes in relation to physiological functions of epididymis is discussed.
