Whether intersex people produce sperm varies depending on their specific biological characteristics.
The answer to whether intersex people make sperm is: it depends. The capacity to produce sperm is linked to specific biological factors. The presence of a penis and the production of sperm indicates the potential for fathering a child, irrespective of being intersex.
According to the provided reference:
"If a person has a penis and produces sperm, they may be able to father a child."
Therefore, the ability to produce sperm in intersex individuals is not a universal characteristic but depends on their individual anatomy and physiology. Many intersex individuals are infertile, but this is not always the case.
