Clinical Characteristics and Reproductive Outcomes in Infertile Men With Testicular Early and Late Maturation Arrest

Maturation arrest has a variety of causes and presents with diverse phenotypes. Not all patients with uniform maturation arrest have a normal follicle-stimulating hormone level or testicular volume. Patients with early maturation arrest have a greater incidence of genetic anomalies and are more likely to have worse reproductive outcomes than are patients with late maturation arrest.
