女
The woman (じょせい) is human sex compared with a man. When I say about biological sex differences by words called the woman, there are cases to say about the many properties of the broad human being who totalled them culture when I say about social sex (gender). To be exact, it is thought that that it is a woman is formed with nature of the sex chromosome, nature of the external genitalia,-related (gender) legal nature that it-related, is social of the internal sex organ, gender identity, 7 of the sexual point by the present. The woman is equivalent to the female of the animal. At first the woman-related grounds are demanded from woman external genitalia and an internal sex organ biologically. There are many cases admitted that the human being that existence of the woman external genitalia was confirmed at the time of birth is a woman first of all. Judging from a modern medical viewpoint, not only the external genitalia but also the internal sex organ is important again. I have an organ such as the womb to bring up the ovary, the fetus whom the woman produces ova, and secrete various kinds of hormones in the body (secondary sex characteristic). Such a biological sex differences come from the model of the chromosome fundamentally. (XX) that the woman in an anatomical meaning such as the above has only an X sex chromosome as a sex chromosome in many cases. I have the apoptosis of the wolf pipe naturally without there being a factor having the apoptosis of positive Muller pipe at the stage of the outbreak because there is not a hormone guiding the part of the male genital organ from a wolf pipe, and Muller pipe develops. By of various heredity or an outside factor, there is the example which it does not apply to closely (it is cf. hermaphroditism). However, the person is usually considered to be a woman if it applies to it almost as above. The judgment on the border line is very difficult, and individual, but the dyeing figure serves as a big role for the judgment a lot. The example that expression is a woman has a sex chromosome with XY type or an XO model, but, as for the most, both the person himself and the circumference are taken as a woman. For example, the former is the adrenal gland sexual organs syndrome that is androgen that an acceptor of androgen formed by a factor on the Y sex chromosome does not function and the secretion obstacle of the male hormone, and the latter is so-called Turner's syndrome. In addition, there is the person assuming that I rarely receive such biological sex difficulty, and there is the case diagnosed as gender identity disorders. That I change a sexual characteristic for appearance by the dosage or the surgical operation of the hormone drug is performed. There is much autoimmune disease such as collagen disease, the Basedow's disease. According to female sex hormone affecting immunity power, this is thought about. In addition, female sex hormone secretion suddenly decreases in the menopause, and risks of the osteoporosis increase. There are more women in a thyreoid disease, the Alzheimer's disease. A woman has much more breast diseases in comparison with the man, too. Generally a woman has a long average life span than a man. This depends on the survival rate of the woman in each age being higher than a man. A survival rate is higher a woman from a moment of the fertilization, and, as for miscarriage or 2/3 of a fetus dying by having a baby born dead, a male thing is reported. It is thought that a biological factor and a social factor affect this. For a biological factor, it is said to the woman having two X chromosomes that there being tolerance for a disease related to a X chromosome, the thing that a woman hormone acts on in favor of the prevention of the cardiovascular disease, a male relative metabolic rate are higher than a woman. In addition, there is the way of thinking that the genetic expression that there is on a Y chromosome is concerned with shortening of the male life because the average life span of the man whom the part of the Y chromosome deletes gets longer. For a social factor, I do thing that male, there is much that I engage in smoking and drinking, overwork, a gamble, dangerous work experimentally, and the woman tending to take the lifestyle desirable more healthfully than a man is thought about. I am passive, and there is much society where a thought to take the dependent viewpoint is traditional, but the tendency to exaggerate existence of such a "tradition" in one is seen in conservative, both people of progressivism for a man. The many custom to make woman and man different handlings is brought into question as "sexism" in equality, a right, a viewpoint such as human rights. Generally, in Japan, a public viewpoint (job responsibilities, a pay level) in the society of the woman is weak. The ratio of the managerial class of the woman in the company, the ratio of the Congresswoman in the assembly are low in the developed nations. On the other hand, there is generally the opinion that a woman does the management of the family budget for reasons of grasping it when the viewpoint in the home is not low. With the plant, it is often that it is compared to a flower like a lily and a rose. If it is an animal, there is a case compared to sheep (a man, wolf) in a fox (a man, raccoon dog), the West in Asia. But I have a bad meaning called the woman the words called the Japanese woman fox deceive a man, and to abduct.
