An individual who has one or more testes and ovaries and whose external genitalia are not clearly male or female. This condition can occur in chimeras who have inherited both a male and a female set of sex chromosomes. True hermaphrodites have one testes and one ovary. Male pseudohermaphrodites, or "merms," have testes but no ovaries and display some female genitalia tissue. Female pseudohermaphrodites, or "ferms," have ovaries but no testes and display some male genitalia tissue.
