Idiopathic melasma in men is rare. This study found higher luteinizing hormone (LH) and lower testosterone levels in men with melasma, suggesting subtle testicular resistance.

Area of Science:

  • Endocrinology
  • Dermatology
  • Reproductive Medicine

Background:

  • Melasma is a common hyperpigmentation disorder, predominantly affecting women.
  • Male melasma is significantly less prevalent, with limited research on its underlying pathophysiology.
  • Idiopathic melasma in men presents a unique clinical challenge.

Purpose of the Study:

  • To investigate the endocrine profile of men diagnosed with idiopathic melasma.
  • To evaluate circulating levels of key reproductive hormones, including luteinizing hormone (LH), follicle-stimulating hormone (FSH), and testosterone.
  • To explore potential links between hormonal imbalances and the development of melasma in males.

Main Methods:

  • Blood samples were collected from 15 men with idiopathic melasma.

  • Hormone levels (LH, FSH, testosterone) were measured in these patients.
  • Results were compared to those of 11 age-matched healthy male controls.

    • Main Results:

    • Men with idiopathic melasma exhibited significantly elevated circulating levels of LH compared to controls.
    • Testosterone levels were markedly reduced in the melasma group.
    • FSH levels did not show a significant difference between the groups (data not shown in abstract).

    Conclusions:

    • The findings suggest a potential role for hormonal dysregulation in male melasma.
    • Elevated LH and low testosterone indicate possible subtle testicular resistance in affected men.
    • Further research is warranted to elucidate the precise mechanisms and clinical implications of these hormonal changes.
