Research in reproductive biology focuses on the events that control ovulation, spermatogenesis, the reproductive organs, fertilization, and the physiology of placentas and fetuses. Studies will continue on the physiologic basic of reproductive behavior and the specific biochemical agents that control such behavior. All investigations, whenever appropriate, will enlist the collaboration of morphologists, physiologists, biochemists, and behaviorists. Our neuroendocrinology area will be strengthened by addition of a scientist who already is at the Center and specializes in neurology and neuropharmacology. Work in cardiovascular diseases will pursue deeper understanding of the mechanisms that control atherosclerosis and the factors that regulate cholesterol metabolism, as well
