• Immature female mice of the SWR/J and C3H/Ibg strains pretreated with PMSG showed higher incidence of ovulation when exposed to males of the same strain than did those kept isolated after weaning. Females of the C57BL/6Ibg strain were not affected. The numbers of eggs ovulated were also greater in SWR and C3H females than in the C57 females. When SWR/J females were killed after exposure to males for 2, 4 or 6 h, there was a 6-fold increase in LH levels at 6 h compared to values in isolated controls. It is suggested that adult male mice of some strains provide a stimulus which promotes release of LH in the immature female.
