What is the reason for late implantation

summary

In general, if ovulation is not fertilized, it is usually from the sixth day to the seventh day after ovulation. Because there is no fertilization, the egg will fall off on the fourteenth day after implantation, but if it is fertilized, it will start to grow after implantation, Because at the time of implantation, the trophoblast cells on one side of the inner cell group will secrete protein to digest the endometrial tissue that it contacts, and then the edge of the blastocyst will be digested, and there will be gaps in the tissue, and then the fertilized egg will be slowly embedded in the functional layer of the endometrium. Now let's get to know.

What is the reason for late implantation

First: if the egg is not fertilized, it will generally be implanted on the seventh day after ovulation, but it will fall off after a week or so. If the egg is fertilized, it will generally be implanted on the seventh day after follicle implantation, but it will not fall off in the future.

Second: if an egg is fertilized, it usually starts implantation on the sixth or seventh day after ovulation. At the time of implantation, the trophoblast on one side of the inner cell group will secrete protein sensitivity, and then digest the inner membrane tissue and the edge of the blastocyst.

Third: after implantation, because the tissue next to the blastocyst is digested, the blastocyst will have a gap, and then slowly embedded into the endometrial functional layer. Generally, the place where the fertilized egg is implanted is in the anterior wall of the uterus or the posterior wall of the uterus or the middle and upper part of the posterior wall of the uterus.

matters needing attention

Under normal circumstances, no matter whether there is fertilization or not, implantation usually starts on the sixth or seventh day after ovulation. If there is no fertilization, it will fall off in a week or so after implantation, and if it does, it will grow there.
