There are only a few case reports that describe patients with MEN1 developing infertility as a further symptom of the disease (9–11), whereas a multigenerational cohort study of the MEN1 population (Tasman 1 MEN1 kindred) controversially indicated no adverse impact of MEN1 on patient fertility overall, but MEN1 may impair the reproductive potential of individuals with pituitary disease (12). The gene discussed is MEN1; the disease is Infertility.
