Xiao Li has always felt that he has a lot of hair "underneath", and he doesn't feel very good-looking, but I heard that shaving it can cause a lot of diseases, so I want to ask, can the hair on the private parts be shaved? Let's talk about this problem together!
Small classes
When does pubic hair appear
Sex hormones restrict the growth of pubic hair, the general female 11~12 years old, the ovaries gradually mature, sex hormones begin to secrete, stimulate the appearance and growth of pubic hair, the presence or absence of pubic hair and its density are affected by two factors: first, the level of androgens produced by the adrenal cortex; second, the sensitivity of pubic hair follicles to androgens.
The role of pubic hair
Protective effect The skin of the private parts is relatively fragile, and pubic hair can avoid direct contact between the private parts and clothing, and protect the skin of the private parts well.
The presence of pubic hair can increase the ventilation space between the private parts and clothes, dissipate heat, let the sweat evaporate better, and avoid the occurrence of eczema.
Cushioning effect Prevents damage to the skin of the genitals and prevents foreign bodies and bacteria from entering the vagina directly.
Knowledge Expansion: Precocious puberty
In females, pubic and axillary hair begin to grow during puberty, but menstruation and pubic hair growth occur before the age of 8 years, precocious puberty may occur. Precocious puberty can be affected by other diseases or conditions.
Precocious puberty refers to the development of secondary sexual characteristics before the age of 8 in girls and 9 years in boys. Boys and girls will have rapid growth in height and weight, girls will show breast development, pubic hair, axillary hair, menstrual cramps, etc., and boys will show increased testicular volume, penis growth, thickening, beard, pubic hair, etc.
According to the pathogenesis and clinical manifestations, precocious puberty can be divided into three main categories.
Central precocious puberty, also known as gonadotropin-dependent precocious puberty or true precocious puberty, occurs in which the child develops the ovaries or testes in addition to the development of secondary sexual characteristics. Central precocious puberty can be further subdivided into idiopathic precocious puberty (also known as constitutional precocious puberty), secondary precocious puberty, and precocious puberty caused by other diseases.
Peripheral precocious puberty, also known as non-gonadotropin-dependent precocious puberty and pseudoprecocious puberty, generally has the development of secondary sexual characteristics and elevated sex hormone levels, but no gonadal development, and the hypothalamic-pituitary-gonadal axis is immature.
Partial precocious puberty, also known as incomplete precocious puberty, such as simple precocious breast development, simple pubic hair precocious appearance, simple early menarche, etc.
Misunderstandings
The more pubic hair, the better
Pubic hair is too lush, which can lead to prolonged exposure of private parts to a humid environment, which can lead to a large number of bacteria and related diseases if not taken care of in time. If you have too much pubic hair, you can shave it off in moderation to make it easier to clean and reduce bacterial growth. And a large number of sweat glands are distributed in the private parts, which is easy to sweat, and excessive pubic hair is also prone to unpleasant odors.
The less pubic hair, the better
There are two sides to everything, too much pubic hair is not good, and too little pubic hair is not so good. If the pubic hair is completely shaved off, the private parts that have lost the "protective umbrella" are prone to friction and collision, which may lead to skin damage and vaginal injuries; Whether to shave pubic hair or not needs to be decided after weighing the pros and cons.
Lack of pubic hair can affect libido and fertility
There are large individual differences in the amount of pubic hair in adult females, and the growth and development of pubic hair is affected by various factors such as race, genetics, nutrition, physique and mental state. In most cases, more or less pubic hair is a normal physiological phenomenon. Studies have shown that sparse or absent pubic hair does not affect sex and fertility. People with scarce pubic hair do not need to worry as long as there are no pathological problems.
