How long can sperm survive in the vagina? Protecting sperm should start from 8 aspects

Some women who want to be mothers may find that even if they are well prepared, they still cannot conceive a baby smoothly. And what changes have sperm, as essential for pregnancy, undergone in women's bodies? How long can it survive? Now, let's take a look together.

The combination of male sperm and female eggs is necessary for women to conceive. Normally, mature males can produce tens of millions of sperm in one ejaculation, but most of these sperm lose vitality and die due to the acidic environment of the female reproductive tract. This is also one of the reasons for infertility. Many people will doubt about this. How long will sperm survive in women?

Generally speaking, the lifespan of sperm in the female vagina does not exceed 8 hours. Then only a small portion of the sperm will escape and continue to move forward. Why is this? Because the sperm in the semen during male ejaculation can be protected by a large amount of fructose and enzymes that break down sugars in the semen, and when the sperm enters the uterine cavity, they leave the semen. At this time, the living conditions are far inferior to those in the semen, resulting in a greatly shortened lifespan. Poor quality sperm run slowly and cannot reach the uterine cavity quickly, thus losing their vitality.

So, after the sperm enters the female body, how long will the sperm survive in the female body? Experts say that after passing through various checkpoints, there are very few sperm left that can ultimately reach the fertilized site of the fallopian tubes.

However, as long as sperm enter the fallopian tube, they have strong fertilization ability. Of course, only 1-2 sperm were fortunate enough to combine with the egg, while the remaining sperm died within 24-36 hours. Only sperm stored in the crypt of the cervical mucosa have a lifespan of 2 to 6 days. However, their fertilization ability has been basically lost, as most sperm can only maintain fertilization for about 20 hours.

The egg has the strongest fertilization ability within 15 to 18 hours after being discharged from the ovary, and can maintain fertilization ability for about 30 hours. Afterwards, the egg begins to degenerate, and fertilization ability rapidly weakens and disappears.

Although sperm injected into the female reproductive tract can survive for up to 4-5 days, the time for strong fertilization ability is 1-2 days, which means that only sexual intercourse within 1-2 days before and after ovulation is possible for a woman to conceive. This is very important for guiding infertile couples in their sexual life. Some couples have no issues with their reproductive function, but due to neglecting the timing of conception, they become infertile for several years after marriage.

In addition, if you want a healthy and lovely baby, in addition to women being prepared, men should also protect their sperm. So, what aspects should we start from?

1. Do not smoke or drink alcohol: Nicotine in cigarettes has the effect of reducing sex hormone secretion and killing sperm, while alcohol in alcohol can also cause poor sperm development or loss of motility. If men drink excessively for a long time, it will cause damage to spermatogenic cells and affect sperm production.

2. Appropriate exercise: Exercise not only maintains healthy physical strength, but also produces excellent sperm. However, during exercise, you should be careful not to engage in intense exercise to avoid fatigue, and wear loose clothing to help dissipate heat.

3. Stay away from radiation from mobile phones, computers, and other devices: Men should not play with computers or make phone calls for a long time. The microwaves generated by these communication facilities can have a significant impact on sperm, and long-term use can reduce sperm count or cause sperm abnormalities.

4. Don't overeat: The growth of sperm requires multiple nutrients. If men overeat, especially when they don't like green food, it can cause nutritional imbalance and malnutrition, which in turn can affect the production and quality of sperm. Therefore, men should eat more milk, eggs, lean meat, fresh fruits and vegetables, etc.

5. Maintain a good mood: If a man is often in a state of tension, depression, and other mental states, it will cause unstable endocrine and testicular spermatogenic functions, which will weaken sperm. Therefore, you should always maintain a happy mood.

6. Stay away from high temperatures: Do not frequently take saunas or hot water baths. Although this type of bathing is both comfortable and fatigue free, it can reduce the number and quality of your sperm.

7. Do not ride a bicycle for long distances: When riding a bicycle, the seat can compress the urethra, scrotum, and perineum. If you ride a bicycle for a long time, it can cause congestion in the perineum, thereby affecting the reproductive function of the testicles.

8. Wear loose fitting clothes: Male friends must choose to wear loose and high-quality clothes, and remember not to wear tight jeans because they can hinder testicular blood circulation and affect sperm production and quality.

9. Keep your body clean: Male friends must keep your body clean. If you have a sexually transmitted disease, you must receive thorough treatment before considering giving birth. If you find any other abnormalities in your reproductive organs, please go to the hospital for examination as soon as possible.
