How long does the fetus enter the uterus

summary

When men and women have sex, it is likely that sperm and eggs will combine to form an embryo, but some people don't know how long it takes for a fetus to enter a woman's womb. Let me explain to you.

How long does the fetus enter the uterus

First: sperm and eggs in the fallopian tube after the formation of fertilized eggs, generally 5-7 days can enter the uterine cavity. When the embryo is small, B ultrasound can not be observed.

Second, after fertilization, the fertilized egg gradually moves towards the uterine cavity. When it reaches the uterine cavity almost 3-4 days later, it has developed into a solid body with multiple cells, which looks like a morula, so it is called a morula.

Third, morulae continue cell division in the uterine cavity to form blastocysts, which enter the endometrium about 6-8 days after fertilization, and then develop after implantation.
