Earthworms are simultaneous hermaphrodites, having both male and female reproductive organs. Simultaneous hermaphrodites (or homogamous hermaphrodites) are individuals in which both male and female sexual organs are present and functional at the same time. [15] Self-fertilization often occurs. [9]
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
In plants, individual flowers are called dichogamous if their function has the two sexes separated in time, although the plant as a whole may have functionally male and functionally female flowers open at any one moment. A flower is protogynous if its function is first female, then male, and protandrous if its function is first male then female.
The human male reproductive system. The human female reproductive system. The male and female perineum. Males and females have different sex organs. Females have two ovaries that store the eggs, and a uterus which is connected to a vagina. The external genitals are called the vulva. Males have testicles that produce sperm.
In invertebrates and plants, hermaphrodites (which have both male and female reproductive organs either at the same time or during their life cycle) are common, and in many cases, the norm. In other varieties of multicellular life (e.g. the fungi division, Basidiomycota ), sexual characteristics can be much more complex, and may involve many ...
But unlike sequential hermaphrodites, simultaneous hermaphrodites are both male and female at sexual maturity. Also sex determination does not apply to simultaneous hermaphrodites (except in species with mix mating systems). [4] In simultaneous hermaphrodites, self-fertilization is possible in some species, where in others it is absent. [5]
In the Tantric sect of Hinduism, there is a belief that all individuals possess both male and female components. This belief can be seen explicitly in the Tantric concept of a Supreme Being with both male and female sex organs, which constitutes "one complete sex" and the ideal physical form. [11] [page needed]
