Abstract

Introduction: melasma is a common acquired hypermelanosis which occurs mostly in face that caused by many factors. One of the pathogenesis of melasma in men is affected by testosterone. This study aimed to investigate the relationship between testosterone levels and melasma in men and its association with the severity of melasma as measured by the melasma area and severity index (MASI) score.

Methods: a case-control study involving 30 subjects with melasma and 30 subjects without melasma who were treated at the outpatient clinic of Dermatovenereology of Ngoerah General Hospital from June to August 2022. Descriptive statistical analysis is to determine frequencies and percentages. Bivariate analysis was used to find any risk factor between testosterone level and melasma. Data obtained from the two groups then analyzed for correlation between the MASI score and testosterone levels.

Results: mean age of the subjects in the melasma group was 43.83±6.30 and in control group was 43.80±6.09. Mean testosterone level in the melasma group (7.55±1.77) was significantly lower than the control group (21.07±6.65; p = 0.001). Subject with testosterone level ≥8.92 nmol/L has 6.9 times risk of melasma compare to control (aOR: 6.986, 95% CI 1.905-25.622; p = 0.003).

Conclusion: low testosterone levels possibly have a role in pathogenesis of melasma in men.
