Physiological structure of hermaphroditism: In the process of human embryo development, SRY gene will make gonad develop into testis, without SRY gene, gonad will develop into ovary. This is also the basis for distinguishing between men and women. However, most people say that people first distinguish between men and women from their sexual organs.
It was not until 2 1 century that basic chromosomes were used to distinguish between men and women. The male is XY and the female is XX, but sometimes there are some errors. So I still judge whether it is a man or a woman from my own will.
Expand knowledge:
Androgyny is also called hermaphroditism. People with hermaphroditic chromosomes may have both male and female secondary sexual characteristics during their development, and may even have both male and female genitals. Hermaphrodites who have complete male and female genitalia at the same time can remove the genitalia of one sex by surgery, thus becoming normal at the gland level.
At first, many people thought that androgyny would only happen to animals. For example, the hippocampus, as we all know, is obviously hermaphrodite. But in fact, humans also have hermaphroditism. This kind of person is not a transsexual person as everyone understands. But born with male and female secondary sexual characteristics.
Androgyny sounds incredible, but there are such people in reality. Some hermaphrodites may have both male and female reproductive organs, ovaries and testicles. These people can later undergo surgery to remove the genitals of a certain sex, thus becoming normal sex people.
But hermaphrodites are mainly due to their chromosomal abnormalities. So under normal circumstances, even if the genitals are removed, even if the gender is differentiated. But in fact, they still have the same characteristics as men and women.
This kind of people are more prone to sex chromosome diseases than normal people. With regard to the incidence of hermaphroditism, the highest estimate is that 1% of live-born babies have a certain degree of gender ambiguity, and 0. 1% to 0.2% of live-born babies will cause medical concerns because of gender ambiguity, including those who have eliminated this phenomenon through surgery. Others estimate that the incidence of true hermaphroditism is much lower, about 0.0 18%.
