Having children is a way for humans to reproduce, but sometimes some humans find that they are unable to have children or that they are prone to miscarriage when they are pregnant. Little do they know that we also need certain conditions to become pregnant. If these basic conditions are met, then it is easy for us to become pregnant. If one of them is not met, we may not be able to become pregnant. So what are these basic conditions? Please see the analysis in this article. These fertility conditions can be roughly divided into the following aspects: 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. 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. 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. All of the above conditions for conception are indispensable, otherwise infertility will occur. The development of the fertilized egg and the growth of the endometrium are carried out simultaneously. If the fertilized egg enters the uterine cavity earlier or later, the endometrium at this time will not be suitable for the fertilized egg to implant and continue to develop, and pregnancy will not be possible. |
