Zusammenfassung:Teratogenicity and developmental abnormalities in the offspring of female rats that ingested ethanol extract of Neem plants during pregnancy and lactation period were assessed. Twenty-four female Wistar rats were randomly distributed in control group and in three experimental groups and treated during the 4th, 5th, and 6th day of pregnancy. After birth, the lactating females received, by gavage, 65, 135 and 200 mg [kg.sup.-1] of Neem ethanol extract, during 15 days. Results show, there was no significant difference in body mass index of neonatal rats in the 4 groups evaluated, whereas mean rate of offspring survival was 79.4%. Hair growth, incisor teeth eruption, ear detachment, eyelid opening, and spontaneous ambulation were similar for all groups. Likewise, physical development and development of motor activity, ambulation, and postural reflexes were similar for all groups. The administration of Neem ethanol extract did not cause any reproductive or systemic toxicity in animals. Results show that, Neem ethanol extract safe at doses 65, 135 and 200 mg [kg.sup.-1] in pregnant or lactating rats. Keywords: medicinal plant, reproduction, teratogenicity, physical development, rodents. Teratogenicidade e anormalidades no desenvolvimento de proles de ratas que ingeriram o extrato etanolico de folhas de nim durante a gestacao e lactacao foram avaliadas. Vinte e quatro ratas Wistar foram distribuidas aleatoriamente em um grupo controle e tres grupos experimentais tratados no quarto, quinto e sexto dias de gestacao. Apos o nascimento, as femeas lactantes receberam atraves de gavagem, o extrato etanolico de nim nas doses de 65, 135 e 200 mg [kg.sup.-1] durante 15 dias. Nenhuma diferenca significativa foi observada em relacao ao indice de massa corporea das femeas em lactacao nos grupos em todos os momentos e a taxa media de sobrevivencia dos filhotes foi de 79,4%. O tempo de crescimento piloso, erupcao dos dentes incisivos, descolamento de orelha, abertura palpebral e deambulacao espontanea foram semelhantes em todos os grupos. O desenvolvimento fisico e da atividade motora, deambulacao e reflexos posturais foram semelhantes em todos os grupos. A administracao nao resultou em toxicidade reprodutiva ou sistemica. Os resultados mostraram que o extrato etanolico do nim e seguro para uso nas doses de 65, 135 e 200mg [kg.sup.-1] em ratas prenhes ou em lactacao.
