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.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.
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.
Intersex describes a wide variety of combinations of what are considered male and female biology.
Intersex biology may include, for example, ambiguous-looking external genitalia, karyotypes that include mixed XX and XY chromosome pairs (46XX/46XY, 46XX/47XXY or 45X/XY mosaic).
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.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.In these groups, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the "female" or "male".For example, the great majority of tunicates, pulmonate snails, opisthobranch snails and slugs are hermaphrodites.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.We have a zero-tolerance policy against illegal pornography.We do not own, produce or host the videos displayed on this website.When a female spotted hyena gives birth, they pass the cub through the cervix internally, but then pass it out through the elongated clitoris.Hermaphrodite is used in older literature to describe any person whose physical characteristics do not neatly fit male or female classifications, but the term has been replaced by intersex.
