Is male body odor hereditary?

Male body odor is generally hereditary. First of all, if you have body odor, you must adjust your mentality and not let it affect your overall good mood. You must face this disease positively and optimistically. Although it is said that it cannot change the genetic genes, it can be treated, so there is no need to worry too much. Body odor is actually the phenomenon of underarm odor caused by excessive sweat secretion. After this disease occurs, it can be treated with professional treatment, so there is no need to worry too much.

Body odor is a hereditary disease that mostly occurs during adolescence. Affected by emotions and hormones, the sweat secreted by the apocrine glands in the armpits of patients is decomposed by bacteria on the skin surface, mainly staphylococci, to produce unsaturated fatty acids and emit a foul odor. According to surveys, 80% of people whose parents both have body odor will inherit it. If only one of the parents has body odor, the probability of inheritance is 50%. The occurrence of body odor is obviously related to heredity. Almost all cases seen in clinical practice have a family history, and one of the patient's parents has such a history. Although surgery removes the patient's own odor, it does not change the patient's heredity, so it can still be passed on to the next generation.

Body odor is hereditary, and its gene should be a dominant gene on the X chromosome. Therefore, theoretically, if both parents do not have body odor, their children cannot have body odor. To explain in detail, males are xy and females are xx. Assume that capital X is the chromosome with body odor. Then xy is a normal male, and Xy is a male with body odor. And xx is a normal female, and Xx and XX are both females with body odor. The next generation of xy and xx can only be xx and xy, which must be normal. The next generation of Xy and xx, the boy must be xy and normal, and the girl must be Xx and must have body odor. The next generation of xy and XX can only be Xy and Xx, which must have body odor. The next generation of xy and Xx has various possibilities, xy, Xy, xx, Xx, that is, 50% of both men and women have body odor. The next generation of Xy and Xx, the boy has a 50% chance of body odor, and the girl will definitely have body odor. Needless to say, the next generation of Xy and XX will definitely have body odor. It can be seen that the probability of female body odor inheritance is much higher than that of male body odor. As the saying goes, men have one odor and women have a nest of odor.

The cause of underarm odor is that the secretion function of the apocrine sweat glands in the armpits is abnormally strong, secreting a large amount of organic matter that is decomposed by bacteria to produce an unpleasant odor. Everyone has apocrine sweat glands, so why do some people have underarm odor and some don't? After years of research, this problem has been basically figured out. The problem lies in the genes. Underarm odor is essentially a genetic disease. We know that the human body has a total of 23 pairs of chromosomes. The problem lies in a gene on the long arm of the 16th pair of chromosomes. A small mutation in this gene causes the secretion function of the human body's apocrine sweat glands to be abnormally strong, secreting some large molecular organic substances (mainly some polysaccharides, I won't go into details) that ordinary people cannot secrete. When the bacteria on the surface of the body obtain these nutritious macromolecules, they reproduce and decompose, producing a lot of substances with special irritating odors, which is underarm odor. The inheritance of this gene is autosomal dominant. In layman's terms, if one parent has axillary odor, there is a 50% chance that the disease will be passed on to the child. It has nothing to do with gender. A mother can pass it on to a daughter or a son, and a father can pass it on to a daughter or a son. In very rare cases, some people have no history of the disease, which may be caused by gene mutation.

After the above introduction, I believe everyone has understood the genetic situation of body odor. Therefore, male body odor is hereditary, but you must adjust your mentality. It can be treated. Although genetic genes cannot be changed, current medical conditions can treat body odor, so there is no need to worry. You must pay attention to personal hygiene and clean in time, take a bath every day and maintain a good mentality.
