The pregnancy is a very curious situation from an immunological point of view. Our defense system, which usually protects the body against foreign cells or against altered own cells, does not consider the cells of the embryo as a hostile organism despite having a different immune system. This happens because our uterus has a specific immunity that allows embryonic implantation.

Occasionally, this local inactivation process of the immune system does not occur correctly and causes an implantation failure. This means that the long-awaited pregnancy is not achieved. This complication appears even in women with good quality embryos and endometrios seemingly without problems. And in most cases, there is an effective treatment that helps to increase the likelihood of a pregnancy.

In the Reproductive Immunology Unit each case of infertility with immune origin is studied, evaluated and treated. A complete profile of those immunological factors related to primary infertility, implantation failure after in vitro fertilisation (IVF), recurrent miscarriages and pre-eclampsia or eclampsia during the pregnancy is performed.
