Abstract
The behavior of rhesus monkey infants exposed to high levels (20 to 100 x the human therapeutic dosage) of an estrogen-progesterone contraceptive (Norlestrin) during embryogenesis was compared to that of untreated controls. No serious deficiencies in regulation of activity, motor maturity, manual dexterity or discrimination learning were recorded in the 3 to 5month old infants. In addition, age appropriate sex-differentiated behavior was observed in social groups of treated infants at 5 and 11 months of age. On the basis of this information it seems unlikely that accidental use 5 month birth control pills during early pregnancy will seriously affect behavioral competence of offspring during infancy.
