Tarasconi et al. [17] showed that miscarriage rates were significantly higher among women with low (0.08–1.60 ng/mL) serum AMH levels than among those with medium (1.61–5.59 ng/mL) or high (5.60–35.00 ng/mL) AMH levels regardless of age or number of oocytes retrieved. This evidence concerns the gene AMH and spontaneous abortion.
