What are the symptoms of testicular hypoplasia?

Patient's question:

Hour check was mumps, now can't have children, the result is testicular problems
The testicles are still underdeveloped

Doctor's answer:

1. Males with hypogonadism due to intellectual disability mostly have normal intelligence, but a small portion of patients may have mild intellectual disability. Due to hypogonadism, the more X chromosomes in males, the easier it is to cause intellectual disability.
2. Patients with hypogonadism and mental abnormalities may exhibit shyness, solitary personality, silence, poor social skills, and some may engage in inappropriate behavior. Some patients may show neurotic tendencies.
3. Disorders of secondary sexual characteristics: Patients with hypogonadism appear male externally, but their testes are small and may have conditions such as cryptorchidism, low libido, or azoospermia. Some patients may also exhibit female characteristics like reduced breast development or sparse body hair.
