Abstract
Summary
The increase in serum gonadotropin concentrations which follows ovariectomy in the rhesus monkey is markedly retarded in lactating animals suckling their infants. This inhibitory influence of lactation is more pronounced for LH than FSH. The LH content of the pituitary glands removed from monkeys is 8% of that found in pregestational adult females while the FSH content is not markedly reduced.
The expert technical assistance of B. Petro, B. Lee-son, E. Burkett, and L. Morrison and of our animal care staff is gratefully acknowledged.
