What studies say
In a study with the US National Library of Medicine National Institutes of Health, vitamin B12 deficiency, infertility and recurrent fetal loss was examined.
The study noted: “The objective of the study is to examine the relationship of infertility to recurrent fetal loss in patients who were vitamin B12 deficient”
The study looked at 14 patients with episodes of a vitamin B12 deficiency who also had a history of infertility.
The study concluded that due to raised homocysteine levels lead to fetal loss when vitamin B12 deficiency first develops.
A more prolonged deficiency results in infertility by causing changes in ovulation or development of the ovum or changes leading to defective implantation.
