The essential characteristic of hermaphrodites is the ability to reproduce as both male and female. No such case has been identified in any human (Puts 2009).

Types of Hermaphroditism

Hermaphrodites are divided into two categories: simultaneous and sequential. Simultaneous hermaphrodites are both male and female from the time of sexual maturity, whereas sequential hermaphrodites switch sexes one or more times during the lifespan.
