Abstract

Female hamsters maintained in groups of 4 to 12 animals continue to show four‐day ovulatory cycles. However, when placed with males on the evening of proestrus, only 40% of these grouped females mate. Ninety‐five per cent of females caged singly or in groups of two, mate in less than ten minutes when placed with males on the evening of proestrus. Thus, grouping of female hamsters blocks reproduction in some individuals through a behavioral mechanism which does not apparently affect the ovulatory cycle. Receptivity cannot be reinitiated in such animals by administration of exogenous progesterone on the afternoon of proestrus.

## Abstract **Scope**: Mangiferin, a natural polyphenol, has been shown to have hypolipidemic effect in rat and mouse. However, the mechanism of action is not well understood. This study was conducted to determine the effect and mechanism of action of mangiferin on hyperlipidemia induced in hamster
