1. High age is limiting even with normal FSH. Original reports demonstrated lower pregnancy rates in women past 40 years of age, no matter their basal FSH level . Even with today’s treatments, successful pregnancies past age 42 are uncommon, and past 45 are rare.
2. High FSH is limiting even with normal age. The original reports saw a declining pregnancy rate as FSH rose above 20, and no ongoing pregnancies beyond an FSH of 25 IU/L [5,6]. While the assay has since changed and altered these cutoffs, there still tends to be a threshold above which declining performance (egg production and pregnancy rate) is detected, and a higher threshold above which egg production is quite limited, and almost no pregnancies have occurred.
3. Cutoffs for FSH depend on the lab test employed. Up through the early…
