For a certain disease, the most frightening thing is not bad treatment, but not knowing how to cure it? Nowadays, the fertility concept of men and women is different from the past, and more people choose to marry later and have children later, delaying the time to have their little ones. However, when these couples put pregnancy on their agenda, they find that it is much more difficult than they thought it would be. Especially for women, even if there is no problem with ovulation test and no abnormality in all aspects of their body, it is still difficult to get pregnant, which makes a wave of friends who are thirsty for self. What are the conditions for pregnancy? 1, the male partner is healthy, can ejaculate high quality sperm, and the higher the concentration of sperm, the better. 2, the female partner is healthy, at least the fallopian tubes are open, and can discharge high-quality, vibrant eggs. 3. The couple should have sex during the ovulation period. In fact, it is not difficult to find that conception is a matter for both spouses. Even if the female partner can ovulate normally, it does not mean that she will be successful in getting pregnant. Analysis of the causes of infertility: Prerequisite: the male partner is normal in all aspects and has high quality sperm; the female partner can ovulate normally. 1. Tubal infertility: Although the female partner has normal ovulation, the eggs cannot meet the sperm smoothly due to various reasons such as blockage of the fallopian tubes and fluid accumulation, so naturally, she cannot get pregnant normally. 2. Immunological infertility: Anti-sperm antibodies may be produced in the female body, affecting sperm vitality and limiting the movement of sperm, leading to infertility. Such antibodies may also exist in men’s bodies. 3. Cervical lesions: The cervix is an important gateway for sperm to enter the uterus, and if there is dysplasia or inflammation, it will affect conception. 4. Deformities in the development of reproductive organs: Due to various congenital or acquired reasons, lesions may occur in the female reproductive organs, some of which may affect the movement of sperm in the body, such as vaginal stenosis, vaginal deformities, etc. Even if there is ovulation, you may not be able to conceive a child. 5. Ovarian abnormalities: The ovaries are the factory where the eggs are produced. If there are abnormalities in the function of the ovaries, it will affect the quality and quantity of the eggs, and it is very possible that they will slowly evolve into lifelong infertility. Although conception is a natural physiological phenomenon, the chances of pregnancy can be increased to a higher level if the preparation period is well planned. By measuring and recording the basal body temperature, we can accurately calculate the ovulation date and the danger period of each menstrual cycle, on the day of ovulation, the egg is the most energetic and if intercourse is arranged on this day, the chances of conception are the highest. If both spouses meet the conditions for conception, they can have sex every day for 2 to 3 days before and after ovulation, and they will be able to conceive a baby soon.
