Testicular melanization has evolved in birds with high mtDNA mutation rates.

Journal of evolutionary biology - 1 May 2011

Galván I, Møller A P, Erritzøe J

Abstract excerpt

Melanin is mainly found in the integument of animals, but it also appears in several extracutaneous tissues. The presence of melanin in testes has been anecdotally reported in all vertebrate groups, but the causes and functions of this melanin remain unknown. Similar to other extracutaneous melanins, testicular melanin may protect male germ cells from oxidative stress. Given the high respiratory activity of...
