Women's breasts bear the mission of nurturing the next generation and have a unique role, so have you ever wondered what men's nipples are for?
When Xiao Jiu was surfing the Internet, he saw such a topic, and many netizens were amazingly humorous.
@烤地瓜: When the mother is away, make do with the baby, you can use it as a pacifier (serious face).
@北风萧萧: Maybe it's used to distinguish between positive and negative sides...
@正义使者: Maybe it's convenient to change sex later, hahaha.
@一路向北: I think it is convenient to do CPR (dog head to save life).
Men don't need to breastfeed or produce milk, but they have nipples. Are nipples a very chicken presence?
Today, let Xiao Jiu take you to increase strange knowledge points~
First, why do boys also have nipples?
Why do men also have nipples? In fact, this has something to do with genes.
In the early stage of development, in fact, the sex has not been distinguished, this stage is mainly according to the gene code of chromosomes, and the genes that carry the breast and mammary glands are exactly on the autosome, so whether male or female, in the 3rd to 4th week of development, will grow nipples.
After the embryo develops to 6-7 weeks, the SRY gene in the male Y chromosome begins to promote the production of male hormones and form a sperm nest, which is divided into male and female sexes.
The development of breasts is inseparable from estrogen, but before entering puberty, both men and women do not secrete estrogen, so before puberty, male and female nipples are very small, and there is little difference.
After entering puberty, women begin to develop breasts because of the effect of estrogen, while men become stronger because of the secretion of a large number of androgens in the body, but the breasts do not continue to develop.
So to put it simply, male nipples are actually formed before the sex differentiation of the fetus.
Second, although you can't breastfeed, men's nipples are not useless
Since male nipples are organs that stop developing after embryonic differentiation, what is the use of not being able to breastfeed like women? The following Xiaojiu will tell you that male nipples still have a role.
Convenient cardiopulmonary resuscitation: cardiopulmonary resuscitation consists of chest compressions and artificial respiration, professionals can definitely easily determine the chest compression site, but ordinary people are not necessarily, at this time the nipple plays a role, the general nipple is below the midpoint of the two-point connection is the compression site. It can be said that nipples can even save a man's life when chest compressions are urgently needed!
Enhance the relationship between husband and wife: there are more sensitive nerves on the nipple, once stimulated, it is very easy to make people feel numb, especially when the couple has sex, by stimulating the nipple can also enhance the interest and enhance the relationship between the couple.
Third, men should also be vigilant against breast diseases
Many people think that only women can suffer from breast diseases, but in fact, if men do not pay attention to breast health, they will also have breast diseases.
1. Breast hyperplasia
In fact, there is also a small amount of estrogen in the male body, especially long-term alcoholism, improper medication, etc., which may disrupt endocrine and induce breast hyperplasia problems such as breast enlargement and nodules.
2. Gynecomastia
Various reasons lead to decreased androgen secretion or increased estrogen secretion in men, resulting in male breast hyperplasia and development, manifested as enlargement of breasts, nipples, areola, or accompanied by hard lumps and swelling pain, a small number of nipple discharge, which is gynecomastia.
The causes of gynecomastia may be the following:
(1) Excessive hormone secretion during puberty. In puberty men, due to increased estrogen secretion, 30% of men may experience symptoms of physiological breast enlargement.
(2) Adult hormone abnormalities. Diseases such as abnormal liver function, chronic nephritis, hyperthyroidism, and testicular tumors in adulthood may cause endocrine disorders, and the rise of estrogen levels in men causes abnormal breast development.
(3) Congenital factors. 60% of male newborns are born with physiological male breast symptoms, and a small number of children are congenital diseases such as congenital anorchisis, congenital testicular tumors, etc., caused by pathological male breast.
(4) Drug factors. Men who take certain drugs that affect hormone levels for a long time may also cause breast development.
(5) Idiopathic factors. If factors such as diseases or drugs have been eliminated, the specific cause of "male milk" cannot be clarified, and it should be considered whether it is daily exposure to pollutants that may affect endocrine, such as chlorine-containing pesticides.
3. Breast cancer
Male breast cancer can occur at any age, but 50 to 60 years old, men and women, have breast tissue, once the breast cells develop malignant tumor lesions, it will develop into male breast cancer.
Men's breasts are much smaller than women's, even if there are abnormalities are difficult to find, the symptoms of general male breast cancer include a painless lump with a hard texture, unclear boundaries and poor activity around the areola, local skin depression of the breast, nipple retraction and inverted or nipple discharge, bleeding, and swollen lymph nodes can be palpated under the armpit.
So far, the cause of male breast cancer is still unknown, but it can be prevented by the following five methods:
- Pay attention to breast hygiene and regularly self-check your breast health
- Pay attention to sudden abnormal changes in the breast
- Develop a healthy lifestyle, do not smoke, drink too much, do not stay up late, and adhere to a regular exercise routine
- Do not blindly use tonic supplements, it is best to take them under the guidance of a doctor
- Have regular check-ups, especially if you don't neglect breast check-ups
After reading the article, I believe everyone also understands why men also have nipples, in fact, it is the cause of genes, and male nipples are not useless. But it is worth reminding that like women often have breast nodules, breast hyperplasia and other problems, in fact, men may also have, if men find breast discomfort in life, should be improved as soon as possible to investigate the cause, do not delay the condition.
