1, sperm survival rate affects pregnancy.
Low sperm motility is asthenospermia. The mobility or speed of sperm directly affects the success of conception. Only the sperm moving forward normally can ensure that the sperm reaches the ampulla of the fallopian tube and combines with the egg to form a fertilized egg. Normal sperm in vitro, before the semen liquefaction, the activity is restricted, once the semen liquefaction, immediately show good sports ability.
Normal male sperm should have more than 70% live sperm after being excreted 1 hour. If less than 50% of the living sperm are abnormal, it is called low sperm motility, also known as asthenospermia. If the sperm is completely inactive, it is azoospermia.
Low sperm motility is a common cause of male infertility.
Low sperm motility is one of the main causes of male infertility. If sperm motility is less than 20%, it is difficult to have children. Experts from Shanghai Yangtze Hospital pointed out that if the sperm's movement function is affected by some factors, especially the forward movement, it will make the sperm unable to swim to the position of the egg at the best time, and fertilization will not happen. In addition, if sperm stay in female private parts for too long, acidic environment will shorten the survival time of sperm.
Sperm vitality is low, that is, sperm does not have enough motivation to swim to the egg and combine with it. Generally speaking, sperm has low vitality and dies before swimming to the fallopian tube. Even if you swim to the fallopian tube, you can't penetrate the egg and become a fertilized egg, so you can't get pregnant naturally.
Low sperm motility will increase the probability of fertilized egg defects.
On the other hand, even if a man with low sperm motility can get his partner pregnant, he can't get pregnant with a healthy fetus. This is because even if the sperm with low sperm activity can combine with the egg, because of the functional defects of the sperm, there will be many deficiencies in the development process, nutrition can not be absorbed, and the standard of prenatal and postnatal care can not be reached, so habitual abortion is inevitable. Sperm dysfunction can lead to stillbirth and habitual abortion.
Therefore, if men suffer from asthenospermia, it will increase the difficulty of conception, but it does not mean that they will never have children, because some patients have mild symptoms of asthenospermia and there is no sperm malformation. So many times, even if the man has asthenospermia, the woman will get pregnant smoothly. For men with severe asthenospermia or sperm malformation, it will be difficult to have children, and even if they are pregnant successfully, there will be teratomas. Many pregnant women will have premature delivery or miscarriage during pregnancy, or it may be caused by insufficient sperm quality, so we should pay enough attention to asthenospermia.
Therefore, friends with low sperm vitality should go to the hospital for detailed examination in time to understand the specific situation, and then choose the appropriate treatment according to the doctor's advice, and then get pregnant after being cured. Only in this way can we avoid the harm of infertility and abortion.
2. Methods to improve sperm survival rate
1, exercise more. Studies have shown that male obesity will lead to the increase of inguinal temperature, which will damage the growth of sperm and lead to infertility.
2. Go to the sauna less. Steam room. High-temperature steam bath directly harms sperm and inhibits sperm production.
3. Eat more green vegetables. Green vegetables contain vitamin C, vitamin E, zinc, selenium and other components that are beneficial to sperm growth. Nuts and fish are rich in omega-3 fatty acids and should be eaten more, which is beneficial to the growth of sperm cells.
4. quit smoking. The data shows. 44% people think that smoking is the most important factor for the decline of sperm count, so it is imperative to quit smoking.
5. Drink alcohol in moderation. Excessive drinking will lead to the decline of sperm quality. Men should strictly follow the recommended daily 14-28 standard cup (containing 8-9g of alcohol), and women should halve it.
6, often go to the clinic for physical examination. Bacterial infection is also an important factor of male infertility, so you should often go to the doctor for chlamydia and prostate examination.
