Is there an optimal range / level for NK cells for fertility?

NK cells are essential in fighting any infections and threats in the body, they can also lead to troubles with keeping pregnancy. Hyperactive Natural Killer cells cause so-called Immune Infertility. What are the normal levels of those cells to consider them as non threatening to pregnancy?

Yes, we have set  the natural ranges for the peripheral NK cells, we have set the natural ranges for the endometrial NK cells and we have set the range for the activity of the NK cells whatever is higher than these ranges that we set, we have to decrease it and and make it below this draw lines or the bottom lines that we have set. Otherwise the chances of the natural pregnancy or from the IVF trials are high enough to fail for a successful pregnancy.
