Intersex is in some caused by unusual sex hormones; the unusual hormones may be caused by an atypical set of sex chromosomes.
One possible pathophysiologic explanation of intersex in humans is a parthenogenetic division of a haploid ovum into two haploid ova.
This contrasts simultaneous hermaphrodites, in which an individual may possess fully functional male and female genitalia.
Sequential hermaphroditism is common in fish (particularly teleost fish) and some jellyfish, many gastropods (such as the common slipper shell), and some flowering plants.
Upon fertilization of the two ova by two sperm cells (one carrying an X and the other carrying a Y chromosome), the two fertilized ova are then fused together resulting in a person having dual genitalial, gonadal (ovotestes) and genetic sex.
Another common cause of being intersex is the crossing over of the SRY from the Y chromosome to the X chromosome during meiosis.
Some humans were historically termed true hermaphrodites if their gonadal tissue contained both testicular and ovarian tissue, or pseudohermaphrodites if their external appearance (phenotype) differed from sex expected from internal gonads.
When a female spotted hyena gives birth, they pass the cub through the cervix internally, but then pass it out through the elongated clitoris.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.For instance, groupers are favoured fish for eating in many Asian countries and are often aquacultured.Most hermaphroditic species exhibit some degree of self-fertilization.
The distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar processes are operating to direct the evolution of selfing in animals and plants.Some people who are intersex, such as some of those with androgen insensitivity syndrome, outwardly appear completely female or male, frequently without realizing they are intersex.Other kinds of intersex conditions are identified immediately at birth because those with the condition have a sexual organ larger than a clitoris and smaller than a penis.Enter the world of unlimited free Hermaphrodites xxx, and you are sure to stay with us for hours!
