In humans, there are two sexes: male and female. Males have male genitalia ( testes) and gonads that produce sperm. Females have female genitalia (vagina) and gonads that produce eggs.
Step-by-step explanation:
In humans, there are two sexes when combining the definition of sex for the genital and gonadal levels: male and female. The male sex is characterized by the presence of male genitalia (such as testes) and male gonads (testes) that produce sperm.
