Analysis of Progestagens

This chapter covers the analysis of steroids with progesterone-like activity, classified as “progestagens”. Steroids in this group include the naturally occurring C21 steroids, progesterone (4-pregnene-3,20-dione) and its metabolites, together with synthetic steroids, such as norgestrel norethisterone (NE), and medroxyprogesterone acetate which also have progestational activity.
