Will pregnancy definitely occur when an egg meets a sperm?

The meeting of eggs and sperm does not necessarily lead to pregnancy. There are many conditions for pregnancy. Generally speaking, to achieve pregnancy, it is advisable to have sex during the ovulation period, so that sperm and eggs have the opportunity to meet and fertilize. However, fertilization does not guarantee pregnancy and implantation. It is also necessary to ensure that the reproductive tract is unobstructed, the environment within the uterus is suitable for the implantation and development of the fertilized egg, and the quality of eggs and sperm, etc., are all key factors affecting pregnancy. The impact of sperm and egg quality is primarily to ensure the quality of sperm and eggs. Only by combining good sperm and eggs can a healthier baby be conceived. If there are quality issues with sperm and eggs, they will be eliminated due to the principle of survival of the fittest in the later stage, leading to embryonic arrest.

Intrauterine environmental impact is another important factor. The intrauterine environment of women will affect the implantation and development of the fertilized egg. If the intrauterine environment is poor, the fertilized egg cannot implant and will not receive sufficient nutrients, resulting in its inability to develop and gestate a healthy fetus.
