A woman wanted to be a mother but could not. Four of her pregnancies resulted in spontaneous abortions, and to achieve her goal she underwent controversial treatment.
Kathryn Berrisfor, 33, and her husband, Joss, were trying to be dads a long time ago. They wanted to achieve this naturally, but all pregnancies presented serious complications. In total, Kathryn went through four abortions spontaneous
"The recommendation was that I continue to try and hope to have my baby at some point," he told the BBC. She is an embryologist in a fertility center and, when she received no explanation or solution, decided to consult her colleagues at the Nottingham Care Fertility Clinic. Many badyzes and studies later, Kathryn and Joss received a detailed diagnosis.
The problem for which pregnancies could not be achieved and resulted in abortions It is that Kathryn and Joss share the same antigen in their immune system. An antigen is a substance that triggers the formation of antibodies and can cause an immune response. "It is for this reason that my body has not seen the sperm of the embryo as something strange (for my own body) and that pregnancy has not not prospered, "they explained. .

In order to solve this problem, the expectant mother had to follow a method called "immunotherapy with lymphocytes". This involves isolating the father's white blood cells in a laboratory and then injecting them to the mother. "The mother's antigens are supplied to the mother, who will be part of the baby, which provokes a reaction from her immune system that will accept her," said Marcelo Cavalcante, researcher at the department of obstetrics and gynecology of the University of Fortaleza, Brazil.
The injections should be done before pregnancy, but it is recommended that the woman continue to receive them during the first weeks of pregnancy so that the immune reaction remains active and thus avoids any risk of abortions spontaneous
"So the next time the egg and sperm came together, my body understood that (the embryo) was a different body and that it triggered the pregnancy process," Kathryn said. He added: "Basically, they made me allergic to my husband's sperm to get pregnant."
Through the procedure, Kathryn and Joss had Mae, their first daughter and soon after, their second child. Both babies were born in perfect health and the pregnancy was held under optimal conditions.Lymphocyte immunotherapy was very beneficial for this woman, but it generated great discussions in the world of medicine . It is banned by the FDA (Food and Drug Administration) in the United States and is not recommended by the World Health Organization (WHO).
In some countries, treatment is available privately in some Latin American countries, such as Mexico, where many American women will do so, and in very few institutions in Asia and Europe, where different prices depending on the country. On average, pre-pregnancy injections cost about $ 1,000 and those that occur during the same period, $ 1,500.
