Can a small amount of sperm really lead to pregnancy?

We all know that pregnancy requires the fusion of sperm and egg cells to form sperm and egg fertilization. Only when the sperm and egg fertilization succeed and the embryo implants can it be considered pregnancy. Under normal circumstances, when the two sides have sex, the density of sperm ejaculated by the man into the woman's body is very high, but only a handful of sperm can actually pass through the vagina and enter the woman's uterus. Maybe not even one-tenth of the number, but what we want is quality rather than quantity, and a large amount of sperm is useless.

So, can a small amount of sperm lead to pregnancy? We all know that women produce dozens of eggs during their physiological period, and these eggs are all basic eggs, among which there are one to two mature follicles. Mature follicles will grow and develop into mature follicles, and only mature follicles will be released during ovulation. In other words, no matter how high the sperm density is, there are only two egg cells. If you want to increase the chance of pregnancy, the quality of sperm and eggs must be good.

In other words, even if there is only a small amount of sperm, as long as the quality of the sperm is good, the chance of pregnancy is still very high. Although the chance of pregnancy is greater with a large amount of sperm, if the quality of the sperm is poor, even if the sperm fuses with the egg cell, the quality of the sperm-egg fusion is not good, the test tube embryo will grow and develop slowly, which will affect the time of the formation of the fetal bud and fetal heart, then the test tube embryo is likely to stop growing and developing, and this test tube embryo will become stillborn.

Although successful embryo implantation means pregnancy, even if pregnancy is successful, incomplete development of the test tube embryo will lead to miscarriage. We often hear that some women need to take fetal injections and take fetal injections to supplement the fetus before they can successfully maintain the fetus. This situation may be caused by poor sperm quality, of course, it may also be caused by other reasons.

Therefore, a small amount of sperm can also lead to pregnancy. As long as the quality of sperm is good enough, there is a possibility of pregnancy. However, many people think that the more sperm a man has, the greater the chance of pregnancy. In fact, it is not true. If the quality of sperm is not good, then no matter how good the sperm is, it is useless. Even if pregnancy is successful, it does not mean that the test tube embryo can grow and develop normally. Therefore, the quality of sperm and egg cells is very important. What we want for sperm is quality rather than quantity.
