I noticed that my fertility vitamins contain a lot of Vitamin B-12. I thought this was interesting and looked up some information about getting pregnant and this supplement. This is what I found on www.womensinternational.com:
“In some cases, doctors have reported that anovulation (a failure to release an egg during the monthly cycle) occurs in some women with B12 deficiency. In these cases, a cause of the B12 deficiency is the decreased production of intrinsic factor (IF), a protein normally made in the stomach, which is necessary for proper absorption of B12. This leads to the development of malformed red blood cells, known as pernicious anemia.
Some studies have noted a link between B12 deficiency and abnormal estrogen levels that may interfere with implantation of the fertilized egg. Dr. Michael Bennett describes a connection linking B12 deficiency with not only a failure to get pregnant but also a failure to successfully carry a baby full-term.
A vitamin B12 deficiency has also been associated with abnormalities of the cells of the reproductive tract, extending to the lining of the uterus and cervix, which might be diagnosed as cervical dysplasia. Observation of these abnormalities caused by a B12 deficiency can also be mistaken for a precancerous condition”.
