Miscarriage, Recurrent Miscarriage And Hormone SensitivityIt's a very interesting theory that miscarriage may be caused by the very hormones that surge during pregnancy. I truly wonder if this might have caused some of my miscarriages - especially since after one of my miscarriages, the fetal tissue was tested and it was chromosomally normal. I recall using one brand of natural progesterone cream that made me nauseated. Also, when I went through fertility treatments, many of the hormonal injections made me nauseous. Additionally, every time I became pregnant, the sickness was almost unbearable. This really does sound like a hormonal sensitivity. Read more about the research:
The researchers injected the hormones into the skin of 29 women who had experienced at least three unexplained miscarriages, and 10 women who had successfully carried a baby to term and never had a miscarriage.
The injections sites, and the arm, were monitored for signs of redness and swelling. All but three of the women in the first group showed hypersensitivity to one of the two hormones, and 17 women showed hypersensitivity to both. None of the women in the control group had a reaction to the test.
"This is really novel," says Walker. "It's a small sample size but if the results are that profound, it definitely warrants more research."
