There are many common names, but there is only one scientific name, named testicles.My brother lives in a scrotum with a constant temperature.I increase with the age of the owner.When the master was ten years old, my volume was only small, and it increased rapidly in the future. When the owner was 17 or eighteen, I was also "adult". The volume reached 12-25 cubic centimeters.EssenceWhen the host was in the fetus, I lived in the owner's abdominal cavity.Generally, I move to the scrotum to live in the scrotum after 7 to 9 months or after the host is born.During my downside from the abdominal cavity to the capsule, due to my own dysplasia or other reasons, my downlink metastases were blocked, and I may still stay in the abdominal cavity, groin tube or other parts.At this time, the scrotum was empty, and people gave me a situation nicknamed "hidden test".Generally speaking, when the owner is newborn, the cryptor test accounts for 10 %, while adults are 0.3 % and most of them are one side, and about 10 % to 20 % of the total on both sides.
The mature I do two things for the owner. One is to secrete the male hormones to keep the owner maintain the male male style; the other is to produce sperm and make the owner a successor.The male hormone secreted by the interstitial cells in my body is called testosterone. It can promote the normal development of male sex organs and sexual characteristics, and maintain its normal state, and make men's males.More than 1,000 fine seizure tubes in my body produce sperm.The life cycle of normal men's sperm is 14-17 days.A normal man can produce 300 million sperm per day, and the number of sperm produced in his life is about 1 trillion.The amount of semen with normal ejaculation once is about 2-6 ml, about 100 million sperm per milliliter, and more than 20-600 million sperm echins.If there are less than 60 million sperm per milliliter semen, less than 85 % of sperm with good activity, and more than 15 % of no vitality or dead sperm, it can be considered abnormal.If there are no such a large and healthy sperm, it will be difficult to ensure that the sperm can be the "Bridge" with the eggs.
I am most afraid of heat.The temperature of the scrotum is 2 degrees Celsius lower than the temperature of the abdominal cavity and the skin, so I choose to settle in the scrotum.I hope my master should try not to wear tight pants as possible, and don't make me close to the skin, otherwise it will affect my sperm function.For the owner of the umbrella, I need to choose the opportunity to move me to the scrotum to settle.The choice of surgery should not be too early, and the possibility of implicit tests of infants and young children may fall into the scrotum.But it should not be too late, and it is too late to make me dysplasia, losing the function of giving birth and secreting androgen.Generally speaking, the owner should do surgery at the age of eight or nine to move me to the scrotum, and the operation should not be late at the age of twelve.It is best to surgical resection for adult men's umbrella, so as not to cause me to suffer from tumors.
Due to environmental pollution, certain bad behaviors and bad lifestyles, I will reduce my reproductive ability, which will affect the owner's reproductive health.The environment with hormone activity & mdash; & mdash; environmental hormones can damage my physiological function.At present, scientists have confirmed that environmental hormones, ambient anti -estrogen, environmental anti -progesterone and ambient anti -roged androgens have been confirmed by scientists.For example, some foods in daily life are not suitable to add hormone substances, some pesticides, detergents and certain plastic products, etc., all exist in hormones, especially chemical structures asrogens, or they are degraded after degradation.Has the effect of estrogen.Once the environmental hormone enters the human body, it will play the role of estrogen, interfere with the hormone in the human body, reduce the ability of sperm, and the number and quality of sperm decreases and the immune capacity is low.Due to environmental pollution, the number of sperm in men's semen has been reduced by almost half in the past ten years.
Unclean sexual behavior seriously threatens my health.Through some unclean behaviors, urethritis, epididymitis, and accessory adenitis caused by some unclean behaviors will affect me to inflammation.Especially after infection with chlamydia and mycoplasma, I have a great harm to me, which reduces my sperm ability, reduces sperm activity, and increases the number of abnormal sperm, leading to male infertility.The key to cutting off and protecting my health is that my owner has to perform safe sex. After suffering from sexually transmitted diseases, he should go to a regular hospital for treatment as soon as possible.
Drug abuse, excessive smoking, alcoholism can damage my sperm function and reduce secretion androgen functions, resulting in a decrease in the number and quality of sperm, and decreased sexual desire.Taking hormone drugs for long -term abuse or ultra -doses can also cause obstacles to my physiological function and affect the generation of sperm.My master must change the bad lifestyle.
