The SRY is then activated in only certain areas, causing development of testes in some areas by beginning a series of events starting with the upregulation of SOX9, and in other areas not being active (causing the growth of ovarian tissues).

Thus, testicular and ovarian tissues will both be present in the same individual.

A closer analogy to hermaphroditism in botany is the presence of separate male and female flowers on the same individual—such plants are called monoecious.

Monoecy is especially common in conifers, but occurs in only about 7% of angiosperm species.

which states that if an individual of a certain sex could significantly increase its reproductive success after reaching a certain size, it would be to their advantage to switch to that sex.

Sequential hermaphrodites can be divided into three broad categories: Dichogamy can have both conservation-related implications for humans, as mentioned above, as well as economic implications.

When a female spotted hyena gives birth, they pass the cub through the cervix internally, but then pass it out through the elongated clitoris.

have criticized medical interventions designed to make intersex bodies more typically male or female.The apparent penis in female spotted hyenas is in fact an enlarged clitoris, which contains an external birth canal.It can be difficult to determine the sex of wild spotted hyenas until sexual maturity, when they may become pregnant.For instance, groupers are favoured fish for eating in many Asian countries and are often aquacultured.Since the adults take several years to change from female to male, the broodstock are extremely valuable individuals.
