What is the process sperm undergoes in a woman's body, and what exactly causes infertility? With these questions in mind, let's take a look at how long sperm can live in a woman.
"The combination of male sperm and female eggs enables a woman to conceive. Normal mature men can excrete tens of millions of sperm at a time, but most of these sperm become inactive and die due to the acidic environment of the female reproductive tract.". This is also one of the reasons for infertility. Many people will ask about this, how long does sperm survive in women?
Generally speaking, the lifespan of sperm in a woman's body does not exceed 8 hours. Then only a small proportion of the sperm will escape and continue to move forward. Why is this? "Because the sperm in the semen during male genital mutilation 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 significantly shorter lifespan. Inferior quality semen runs slowly and cannot reach the uterine cavity quickly, resulting in loss of vitality.".
So, after sperm enters a woman's body, how long does the sperm survive in the woman's body? Experts say: After passing through various checkpoints, there are few sperm left that can finally reach the fertilized site of the fallopian tube.
After the egg is discharged from the ovary, the fertilization ability is strongest within 15-18 hours, and can maintain the fertilization ability for about 30 hours. After that, the egg begins to degenerate, and the fertilization ability rapidly decreases and disappears.
Although sperm injected into the female reproductive tract can survive for a maximum of 4-5 days, it has a strong fertilization ability for 1-2 days, which means that only within 1-2 days before and after ovulation can a woman become pregnant. This is very important for guiding the sexual life of infertile couples. Some couples have no problems with their reproductive functions, but they neglect the timing of conception and become infertile for several years after marriage.
"You have always been healthy and have no bad habits, but how can you never expect the arrival of your baby? Have you ever thought that the cause of your infertility actually lurks around you, but you haven't noticed it?"? Below is a list of 10 "killer foods" that can easily lead to infertility. If you want to be a mother, you should be careful!
Long-term vegetarian diet can reduce female fertility
In recent years, a vegetarian diet has become increasingly popular. Especially for women with a full body, they even make vegetarianism a habit, hoping to achieve the goal of losing weight. There is no denying that vegetarian diets do help to lose weight. However, recent medical research on vegetarianism has confirmed that frequent vegetarian consumption by women can affect hormone secretion in the body, and even lead to infertility.
Among the numerous studies on the impact of vegetarianism on women's fertility, the conclusions of the Maasbourland Institute in Munich, Germany, are the most striking. Professor Karlbauk of the college divided the healthy young girls participating in the experiment into two groups. One group consumed only a small amount of cheese and milk, and all other foods were vegetarian; The other group ate normal food.
After a six week weight loss program, researchers found that 78% of women who ate vegetarian diets experienced a physiological phenomenon of stopping ovulation, and almost all groups had shorter menstrual cycles than normal. However, in the normal diet group, 67% of women ovulate normally and have no significant changes in their menstrual cycle.
High fat foods can cause infertility
Expert research in mice has shown that foods with high fat content can damage eggs in the ovaries and prevent them from becoming healthy embryos. This research result can be used to explain the problem of infertility in obese women.
"The experiment found that infertility in mice is mainly caused by a specific protein, which determines the ovarian response to fat," the researchers said. "Controlling this protein plays an important role in exploring the causes of food induced infertility."
