Hermaphrodite
From Memory Alpha, the free Star Trek reference
Hermaphrodism refers to having two or more sexual characteristics or biological functions combined. Unlike the androgynous, hermaphrodites have the capability of being male or female during a sexual process, or undergoing a functional transformation from one gender to another.
The Tholians are a hermaphroditic species, in which individuals have both male and female characteristics. (ENT: "In a Mirror, Darkly")
- In the Star Trek: New Frontier novel series, the Hermat species is described as also having this type of sexual makeup.
