The proportion of deaths during gestation, abortions, resorptions, runting, offspring stillbirths and the rate of offspring mortality was increased. However, no unusual number of specific deformities was encountered. Teratogenicity during any particular organogenetic period was not demonstrated. Treatment during the first seven days was found harmful; treatment later in pregnancy was ineffective. The LSD effects appear to be dose-related and persist into the second generation. © 1970, by The Williams & Wilkins Company
