Most of the progestogens used today do indeed carry such a group in their original molecules. However, the 3-keto group is initially missing in the case of desogestrel and norgestimate. They are prodrugs which undergo metabolic conversion to active 3-keto derivatives in the body.}} 4. ^{{cite journal | vauthors = McRobb L, Handelsman DJ, Kazlauskas R, Wilkinson S, McLeod MD, Heather AK | title = Structure-activity relationships of synthetic progestins in a yeast-based in vitro androgen bioassay | journal = J.
