Women whose most recent miscarriage was classified as “without an embryo” (37/79, 46.8%) revealed significantly lower AMH levels than women whose most recent miscarriage was classified as embryonic/fetal miscarriage (42/79, 53.2%; median 0.7, IQR 0.2–18, versus median 1.8, IQR 1.3–3.3, respectively, p = 0.045) while patient age and the other ovarian reserve parameters showed no significant differences. The gene discussed is AMH; the disease is Miscarriage.
