Os efeitos da administração do óleo das sementes de Azadirachta indica (Neem) foram investigados sobre a fase de pré-implantação em ratas Wistar adultas. Três grupos (n = 5-9/grupo) de ratas foram tratados do 1º ao 6º dia de prenhes por via oral com óleo de neem nas doses de 1,0 e 2,0 g/kg de peso. No 20º dia de prenhez procedeu-se à eutanásia e, em seguida, foram determinadas as variáveis reprodutivas: números de fetos vivos e mortos; relação feto/mãe, massa dos fetos, das placentas e dos ovários, número de implantação e reabsorção, número de corpos lúteos e perda de pré e pós-implantação. Os resultados mostram que não houve diferenças estatísticas entre os grupos tratados e controle nas variáveis analisadas, excetuando-se a massa dos fetos que foram reduzidas em relação ao grupo controle em 10,9 e 12,1% respectivamente para as doses de 1,0 e 2,0g/kg. Dessa forma, conclui-se que a administração do óleo de Azadirachta indica (Neem) não produziu efeito anti-implante, entretanto a redução da massa fetal pode indicar fetotoxicidade.
