Serum norethisterone (NET) levels in NET-enanthate (NET-EN) injectable contraception users substantially interfere with testosterone immunoassay measurements and confound interpretation of biological outcomes

Abstract Background The progestin norethisterone (NET), which is structurally related to testosterone, and its enanthate form (NET-EN), are used in contraception in women. Oral NET has been shown to interfere with testosterone measurements by some chemiluminescence microparticle immunoassays (CMIA)....
