Disorders of Pubertal Development: Too Early, Too Much, Too Late, or Too Little

Major disturbances of pubertal development and variations of normal puberty are discussed. The authors highlight four kinds of pubertal disorders: "too early" (precocious puberty), "too much" (gynecomastia, macroorchidism, and hyperandrogenism), "too late" (delayed puberty), and "too little" (hypogonadism).
