Congenital testicular dysgenesis, or Koch’s syndrome, is a congenital genetic chromosomal disorder. Congenital testicular dysplasia, i.e. Kirschner’s syndrome, is a male testicular dysplasia due to congenital genetic factors, i.e. there is an extra female X chromosome on top of the male chromosome, which fails to produce spermatozoa and maintain normal sexual function in adulthood, and is mainly characterized by a taller body size, smaller testes bilaterally, and enlarged breasts on both sides. In the clinical treatment of this disease, testosterone propionate or methyltestosterone tablets are usually taken sublingually, and long-acting testosterone such as testosterone enanthate or testosterone cyclopentylpropionate can also be given, the specific use of medication should also be carried out under the guidance of a physician on doctor’s advice, and should not be blindly self-medication. It is recommended that patients go to regular hospitals in time for treatment.
