Some of the common causes of dark spots on testicles are hyperpigmentation, age spots, pigmented moles, hemangiomas, and trauma.
1. Hyperpigmentation: the content of sex hormones at testicles is high, and long-term stimulation may lead to deepening of the color of the epidermis of the scrotum, resulting in the appearance of black spots. This is a normal physiological phenomenon and usually requires no treatment.
2. Age spots: related to the aging of the skin, mostly seen in the elderly population. They appear as dark-colored or black patches, usually without obvious symptoms, and most of them do not need treatment.
3. Pigmented nevus: can occur in any part of the body, including the testicles. Pigmented nevi are very common and most do not require treatment. If the black spot is too large, it can also be treated with physical methods such as laser.
4. Hemangioma: If the endothelial cells of blood vessels in the testicle area proliferate abnormally, it will easily lead to hemangioma, which is manifested as dark spots on the testicle and mostly accompanied by local skin elevation.
5. Trauma: when the testicle area is squeezed and other traumas, it is easy to cause the rupture of the small blood vessels under the skin, which leads to blood stasis and the formation of black spots. At this time, it is recommended to avoid strenuous exercise, if necessary, surgical treatment.
When black spots appear on the testicles, it is recommended to identify the specific causes and target treatment.
