Enhancement of Sexual Behavior in Female Rats by Neonatal Transplantation of Brain Tissue from Males

Abstract
Transplantation of preoptic tissue from male rat neonates into the preoptic area of female littermates increased masculine and feminine sexual behavior in the recipients during adulthood. This suggests that functional connections develop between the transplanted neural tissue and the host brain. A new intraparenchymal brain transplantation technique was used to achieve these results.
