Conteúdo: |
Ten pregnant Angora goat does were used to investigate the effect of intrafoetal administration of androstenedione on maternal oestrogen levels and pregnancy. In the experimental group 66,7% aborted while no abortions occurred in the control group. Oestrogen levels in androstenedione-treated animals increased abruptly from 29,7 ng ml to 65,5 ng ml while that of control animals remained relatively constant at 25,5 ng ml. It is concluded that the abortifacient effect of excessive androstenedione in the foetal circulation is mediated via an elevated level of maternal oestrogens. |
