Abstract

This study investigates links between leptin and reproduction in the seasonally breeding Siberian hamster where photoperiod drives major changes in metabolism, body fat reserves and reproduction. Physiological levels of leptin will be administered and changes in hypothalamic drive on the reproductive system monitored by measuring LH output in steroid- clamped animals. We will thus establish whether leptin is capable of reactivating reproduction in photoperiodically suppressed adult animals as well as in animals in which LH secretion is suppressed by under-nutrition. The hypothalamic expression of orexogenic/anorexic peptides, including the CRF/urocortin axis will be determined and the linkage to leptin/photoperiod defined.
