ethisterone การใช้

Closely related analogues of ethisterone include vinyltestosterone, allyltestosterone, methyltestosterone, ethyltestosterone, and propyltestosterone.
Vinyltestosterone has been described as a weak AAS, though stronger than its 17?-ethynylated analogue ethisterone.
Due to its androgenic activity, ethisterone has been associated with the masculinization of female fetuses in women who have taken it during pregnancy.
However, in spite of its improved potency over ethisterone, it is a weak progestogen relative to most other progestins, in fact one of the weakest known.
The improved potency of dimethisterone due to 6?-methylation reportedly served as the basis for the synthesis of medroxyprogesterone acetate . medroxyprogesterone acetate shows 10 to 25 times the potency of ethisterone.
