Stochino-Loi et al. [64] conducted a retrospective study to see if surgery for severe endometriosis could be recommended in women with low (1–1.99 ng/mL) and very low AMH level (1 ng/mL) ovarian reserve with good pregnancy outcomes when compared to postoperative pregnancy rate in women with normal AMH level (>2 ng/mL). The gene discussed is AMH; the disease is endometriosis.
