The mammalian pseudo-penis appears to be simply for display, though the spotted hyena is an exception: the female spotted hyena urinates, copulates, and gives birth through her pseudo-penis. This prevents males from mating without the full co-operation of females, which means that mating preferences of the female are predominant.
Sexual mimicry can play a role in the development of a species' social system. Perhaps the most extreme example of this can be seen in the spotted hyena, Crocuta crocuta. [1] Female hyenas of all ages possess pseudomasculinized genitalia, including a pseudopenis formed from the clitoris, and a false scrotum formed from the labia.
A female spotted hyena's apparent penis is in fact an enlarged clitoris, which contains an external birth canal. [29] [30] It can be difficult to determine the sex of spotted hyenas until sexual maturity, when they may become pregnant. When a female spotted hyena gives birth, she passes the cub through the cervix internally, but then passes it ...
Males in most hyena species are larger than females, [34] though the spotted hyena is an exception, as it is the female of the species that outweighs and dominates the male. Also, unlike other hyenas, the female spotted hyena's external genitalia closely resembles that of the male. [35]
Hence there is a theoretical expectation that females tend to be larger in species that are monogamous. Females are larger in many species of insects, many spiders, many fish, many reptiles, owls, birds of prey and certain mammals such as the spotted hyena, and baleen whales such as blue whale. As an example, in some species, females are ...
The tail is short and the terminal hairs do not descend below the achilles tendon. [16] The female striped hyena's genitalia are transiently masculinized, [17] although it lacks the enlarged clitoris and false scrotal sack noted in the female genitalia of the spotted hyena. [18] The female has 3 pairs of nipples. [19]
“The sex characteristics a person is born with do not signify a person's gender identity,” adds Golob. “When people have ‘gender reveal parties,’ it really should be called a ‘genital ...
Sequential hermaphroditism is very rare and according to scientists this is due to some cost that decreases fitness in sex changers as opposed to those who do not change sex. Some of the hypotheses proposed for the dearth of hermaphrodites are the energetic cost of sex change, genetic and/or physiological barriers to sex change, and sex ...
