PLOD1 and Infertility: Chang et al. (2010) [13] in a different study in China on 60 infertile women measured levels of AMH, inhibin B, FSH, LH, and estradiol on third day of the menstrual cycle and found that there was a significant difference between AMH levels on the third day of the menstrual cycle in fertile and infertile women, and concluded that AMH is correlated better with the number of recovered oocytes than with age, FSH and inhibin B. Women whose AMH levels were within the range of 4.4 ± 2.2 had a better response than women whose AMH serum levels were 0.7 ± 0.8 (P < 0.01) [13].
