The Co-cultivation of embryos is a procedure of taking a small number of endometrium cells one or several months before the stimulation. This manipulation stimulates the development of the lining of the uterus, and this additionally supports the possibilities of embryo implantation. It is followed by treatment and rising the cells before they start to multiply. When the needed quantity is reached, they are they are frozen and stored at -196 degrees Celsius in liquid nitrogen.

The women should pass hormonal stimulation. Some days before follicular puncture and the oocyte collection the frozen cells of the uterine lining are thawed and "seeded" again in the petri dish where the embryos will raised. Their cultivation goes on till the day of the embryo transfer when the ready embryos are put back into the woman's uterus.

Under natural conditions, the embryo in the women body is always in contact with different types of cells.

So the embryos are stronger and with better qualities, so the chances for implantation are bigger.

Why does it help?
