A reproductive system where individuals mature as males, but may reproduce as females later in life.
In most animals, “males” and “females” are distinct classes of individuals that specialize in the production of sperm and eggs, respectively. However, a substantial minority of species are hermaphrodites, meaning that a single individual can produce both eggs and sperm, either simultaneously or at different stages of its life. “Protandrous” hermaphrodites begin their reproductive lives as males, but reproduce as females later in life.
