List of progestogen esters
This is a list of progestogen esters, or esters of progestogens. Unlike the case of testosterone and estradiol, progesterone cannot be esterified as it lacks hydroxyl groups, so all progestogen esters, with the exception of esters of 17α-hydroxyprogesterone like hydroxyprogesterone caproate, are esters of progestins (synthetic progestogens) and are non-bioidentical.
