Prediction of fetal sex in cattle by testosterone levels in allantoic fluid
J Reprod Fertil.
1976 Mar.
Abstract
The testosterone concentration in allantoic fluid between 90 and 150 days of gestation in cattle can be used to determine the fetal sex; values were 442 +/- 20-3 (S.E.M.) pg testosterone/ml for males fetuses and 215 +/- 8-2 pg/ml for female fetuses.
