Where is the egg fertilized

It is well known that under normal circumstances, the combination of egg and sperm forms a fertilized egg, which is a very important process. It takes 10 months for the sperm and egg to develop into a fetus. However, in addition to understanding these relevant knowledge, many young couples are more concerned about where the egg is fertilized, so that they can understand the structure of the body and the process of fertilization, and how to become pregnant successfully.

Where is the egg fertilized

From a medical point of view, the fertilization process includes: the ovaries release normal eggs; the fallopian tubes pick up the eggs and transport them to the normal fertilization site. Normal sperm are very active and have good mobility, and can enter the female body for fertilization. Since the survival time of eggs and sperm in the body is relatively short, sexual intercourse must be performed at the right time to achieve conception.

Fertilization conditions:

1. Men's testicles can produce normal sperm. The amount of semen ejaculated by a normal adult male at one time is 2-6 ml. The number of sperm in each ml of semen should be more than 60 million, more than 60% of the sperm are motile, and less than 30% of the sperm are abnormal. If the sperm does not meet the above standards, it will not be easy for the woman to become pregnant.

2. A woman's ovaries can produce healthy and mature eggs. For women with normal menstruation, a healthy and mature egg is released in each menstrual cycle, which gives them a chance to become pregnant. It is not easy for women to conceive due to ovarian insufficiency or irregular menstruation that causes anovulation.

3. Have normal sexual life before and after the female ovulation period to give the sperm and egg a chance to meet and fertilize. Sperm can survive in the female vagina for 1-3 days, and the egg can survive for about 1 day after being released. The female ovulates about 14 days before the next menstrual period. Conception is possible only if sexual intercourse occurs within a few days before and after ovulation. Having sex during the non-ovulatory period will not result in pregnancy.

4. The reproductive tract must be unobstructed. The male's vas deferens must be unobstructed so that sperm can be discharged through normal sexual intercourse and enter the female reproductive tract to combine with the egg. The female reproductive tract must also be unobstructed so that the sperm that enters the vagina during sexual intercourse can pass through the cervix and uterus unimpeded and reach the fallopian tube to meet the egg for fertilization. The fertilized egg can also enter the uterine cavity smoothly. If the fallopian tube is blocked, the sperm and egg will lose the opportunity to combine, so once the fallopian tube is blocked, the chance of natural conception is completely lost.

5. The intrauterine environment must be suitable for the implantation and development of the fertilized egg. After the egg is fertilized in the ampulla of the fallopian tube, it develops while moving through the fallopian tube toward the uterus. It reaches the uterine cavity after 3-4 days, is buried in the nutrient-rich endometrium after 6-8 days, and then continues to develop into a fetus. It is impossible to get pregnant.

6. Under normal physiological conditions, if a couple lives together without taking any contraceptive measures, the chance of conception is 20% per month, 70% per six months, and 80% per year. If they do not take any contraceptive measures for more than one year and remain infertile, a medical examination should be conducted.
