What causes black testicles in newborns?

Many parents may find that their newborn boys tend to get black all over. This situation is quite worrying for parents, who are afraid that it will affect the growth and development of infants and young children. There are many reasons for this situation. It may be caused by genetic skin color, local pigment deposition, or stimulation by maternal hormones, etc. The following is a detailed introduction to the causes of black testicles in newborns.

Scientific care for newborns is a profound subject. Especially for those who are new to being mothers or fathers, they may not have any common sense at all. Many people have asked about the fact that the color of a boy's testicles is different from the color of other parts of the body after he is born, and the color is darker or even black. In fact, the main reason for a boy’s testicles to turn black is that the baby is affected by the hormones in the expectant mother’s body before he is born. This does not require treatment.

It is normal for a newborn boy to have black testicles. Many newborn boys have darker reproductive organs when they are born. These symptoms are usually normal. Parents don’t need to worry. They can just clean the baby’s testicles according to daily care.

1. Caused by genetic skin color. If the baby's parents have darker skin, then when the newborn boy is born, not only will his testicles be darker, but the skin color of other parts of his body will also be darker. This is because the testicles are dark due to genetic factors.

2. Local pigmentation: If the baby's testicles are darker than other parts of the body, it may be caused by local pigmentation. This is not a disease and parents do not need to worry.

3. Affected by maternal hormones. Before a newborn baby boy is born, when he is still in his mother's belly, the hormones in his body may come from his mother. But after birth, because the umbilical cord is cut, the newborn baby boy is stimulated by the maternal hormones during the fetal period and the accumulation of excessive body fluids during delivery, which causes the baby's testicles to turn black.

4. The weather is relatively cold. If a baby boy is born in winter, his scrotum will shrink due to the cold weather, causing the surrounding wrinkles to deepen and the color to become darker. This is the normal temperature regulating function of the scrotum, which is used to maintain a constant testicular temperature.
