Neonatal treatment with allylestrenol or diethylstilbestrol (DES) reduced the bone mineral content (BMC/bw) of the adult (four months old) female rats, without influencing bone mineral density (BMD/bw). In males these neonatal treatments elevated BMC and BMD alike. Ovariectomy alone decreased BMC and BMD alike; however the neonatal hormone treatments did not influence this reduced value. Ovariectomy of two months old animals increased body weight without the influence of neonatal hormone treatments. In adult males, the body weight was reduced significantly by neonatal DES and non- significantly by neonatal allylestrenol treatment. The experiments call attention to the possible human bone-effects of allylestrenol, which was used in the last decades as medication protecting endangered pregnancies.
