Risk of sexual dysfunction with progestin-based contraceptives in women of child-bearing age.

Abstract

To examine whether there is a positive association between sexual dysfunction (SD) and different types of progestin-based contraceptives. Nested case-control study in women of child-bearing age (15-45 years) from the IQVIA® Ambulatory electronic medical record database from 2008 to 2018. Cases defined by diagnosis of sexual dysfunction identified by international classification for disease clinical modification code 9th and 10th. Each case was matched to four controls and rates of prescriptions of the following were compared: levonorgestrel intra-uterine device (IUD), progestin, and ethinyl estradiol (EE) combined oral contraceptive (COC) formulations including levonorgestrel, norgestimate, drospirenone, desogestrel, norethindrone, and norgestrel; etonogestrel vaginal ring; and medroxyprogesterone injection. Overall, 6689 cases of patients with SD were matched to 26,756 matched controls. Compared with matched controls, more subjects with SD used levonorgestrel IUD (OR 1.24, 95% CI 1.08-1.44), EE-levonorgestrel COC (OR 1.18, 95% CI 1.00-1.41), EE-drospirenone (OR 1.28, 95% CI 1.00-1.67), and medroxyprogesterone (OR 1.38, 95% CI 1.12-1.70). The use of norgestrel exhibited a protective effect (OR 0.83, 95% CI 0.73-0.95). When using the EE-levonorgestrel COC as a comparator, norgestrel users exhibited a protective effect (OR 0.70, 95% CI 0.57-0.87) while no other contraceptives showed a statistically significant difference in association with SD. Our study found an increase in the use of levonorgestrel (COC and IUD), drospirenone, and medroxyprogesterone in subjects with SD. The risk of contraceptives did not differ when compared with oral levonorgestrel. The small association size and lack of difference between drug formulations suggest a minimal impact of progestin-based contraceptives on sexual dysfunction.
