Lipid pattern in female reproductive tissues during different phases of estrous cycle.
The normal pattern of lipids during various phases of estrous cycle in different reproductive tissues of female rats was analysed. The various lipid calsses undergo striking cyclical changes in harmony with the rhythm of endogenous gonadal and gonadotrophic hormones. A comparison of lipid pattern was made between various phases of estrous cycle. Ovary exhibited marked alterations in the distribution of lipids in different phases of the cycle compared to other tissues. Total lipids were maximum in diestrus phospholipids in estrus with a concomittant fall in triglycerides in all the tissues. The fluctuation in oviductal and vaginal lipids was much less compared to other tissues. Hormone-lipid interrelationship and tissue specificity may be attributed to these changes.
