The Impact of Progestin-only Contraception on Adolescents with Macromastia


Progestin-only contraception has become increasingly popular among adolescents. However, patients, parents, and providers share concerns regarding the potential impact that progestin-only contraception may have on breast growth. We sought to explore the impact of progestin-only contraception on breast hypertrophy and symptomatology in adolescents with macromastia. Methods: Patients between the ages of 12 and 21 years undergoing reduction mammaplasty were prospectively assessed for baseline and postoperative breast symptomatology and medication use. The medical records of female controls within the same age range were retrospectively reviewed. Results: A total of 378 participants with macromastia and 378 controls were included in analyses. A higher proportion of controls used progestin-only methods compared with participants with macromastia (28.0% versus 5.3%, P < 0.001). The most commonly prescribed methods were the depot medroxyprogesterone acetate injection (31.0%), levonorgestrel-containing intrauterine device (31.0%), and subdermal implant (26.2%). Patients with macromastia who used progestin-only contraception had a greater amount of breast tissue resected during reduction mammaplasty (P = 0.04), reported greater musculoskeletal pain (P = 0.008), and were roughly 500% more likely to experience breast pain (odds ratio, 4.94; 95% confidence interval, 1.58-15.47; P = 0.005) than those with macromastia who never used hormonal contraception. Conclusions: Adolescents with macromastia who use progestin-only contraception may have greater breast hypertrophy and worse breast and musculoskeletal pain. When appropriate, providers may wish to consider other contraception methods for patients who are at-risk for breast hypertrophy or those who suffer from macromastia-related symptoms.
