Hermaphrodite

From Food & Medicine Encyclopedia

(Redirected from True hermaphroditism)

Hermaphrodite is a term used in the field of biology to describe an organism that has complete or partial reproductive organs and produces gametes normally associated with both male and female sexes. Many taxonomic groups of animals (mostly invertebrates) do not have separate sexes and are hermaphrodites. In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which both partners can act as the "female" or "male".

Etymology[edit]

The term "hermaphrodite" originates from Hermaphroditus, the son of Hermes and Aphrodite in Greek mythology, who was fused with a nymph, Salmacis, resulting in one individual possessing physical traits of both sexes.

Types of Hermaphroditism[edit]

There are three types of hermaphroditism: simultaneous hermaphroditism, sequential hermaphroditism (protogyny and protandry), and pseudohermaphroditism.

Simultaneous Hermaphroditism[edit]

In simultaneous hermaphroditism, an individual has both male and female reproductive organs at the same time. This is common in invertebrates such as earthworms, slugs, and snails.

Sequential Hermaphroditism[edit]

In sequential hermaphroditism, an individual changes its sex at some point in its life. This can be further divided into two forms: protogyny (where an organism is born as a female and changes sex to a male) and protandry (where an organism is born as a male and changes sex to a female).

Pseudohermaphroditism[edit]

Pseudohermaphroditism, or intersexuality is when an individual's secondary sexual characteristics do not match the gonads they possess.

In Humans[edit]

In humans, conditions that involve discrepancies between external genitalia and internal reproductive organs are described by the term intersex.
