The size of the testicles in Crohn’s syndrome is usually abnormal. Kirschner’s syndrome, also known as congenital varicocele syndrome, usually results in small, hard testicles, male feminization, and breast hypogonadism, which are usually abnormal for Kirschner’s syndrome testicle size. In Crohn’s syndrome, low body weight, small head circumference, small penis and cryptorchidism may occur in infancy; in childhood, it may cause speech disorders, learning difficulties and mental retardation; in puberty, it may cause small testicles, which are noticeably smaller than those of the same age, and have a firm texture to touch, similar to the forehead, and a taller stature, and a small number of patients may develop breasts and have a reduced bone density. If you suffer from Crohn’s syndrome, please consult the doctor promptly and treat it aggressively.
