After completing sexual activity, men will leave their semen in the woman's body, and after a long journey, the surviving sperm can successfully conceive. During this process, women generally do not have significant reactions, just like some women who have successfully conceived do not know they are pregnant. Let's take a look with the editor below, what are the body's reactions during the fertilization process?
What are the body's reactions during the fertilization process
1. The process of fertilization and implantation of fertilized eggs is generally non reactive. After entering the vagina, sperm can survive for 2-3 days. If ovulation occurs during this period, conception will occur. The lifespan of an egg is also about 2-3 days, while it takes 1 day for sperm to travel from the vagina to the fallopian tube, and 2 days for fertilized eggs to implant. So the time for conception after sexual intercourse should be 2+1=3 days. The fertilized egg can only be considered pregnant after successfully implanting in the uterus. On the the fourth day, the physiological reaction of pregnancy was just at the beginning, the enzyme system during pregnancy had not been activated, the metabolites had not been accumulated, and the detection sensitivity of the test paper could not reach the effect of clear resolution. You can use test strips to judge after 3 weeks.
2. At the same time as the fertilized egg begins to undergo mitosis, it moves towards the uterine cavity through fallopian tube peristalsis and cilia pushing. Around the third day after fertilization, it divides into a solid cell mass consisting of 16 cells, known as the morula (early blastocyst). On the fourth day after fertilization, the early blastocyst enters the uterine cavity and continues to divide and develop into the late blastocyst. The process of late stage blastocyst invasion into the endometrium after the disappearance of the zona pellucida on the 6th to 7th day after fertilization is called implantation of the fertilized egg.
The above is the relevant information compiled by the editor on the body's reactions during the fertilization process. Frequently learning about scientific knowledge can be very useful, and it is only when it is applied that one realizes how useful it is. During the process of conception, it is important to maintain good physical health. Without a healthy body, conception cannot be successful. After all, one's own body is the most important, and it is the capital of revolution.
