Oral contraceptives vs injectable progestin in their effect on sexual behavior.

Objective: We sought to compare sexual function and hormone concentrations in combined oral contraceptive (COC) and injectable progestin users.

Study Design: Sexually active COC and depot medroxyprogesterone acetate (DMPA) users completed the Female Sexual Function Index (FSFI) questionnaire, a demographic data form, and had serum testosterone and estradiol levels measured. Multiple linear regression was used to measure associations of interest.
