47XYY syndrome cannot be cured because it is a chromosomal abnormality, which may be caused by the chromosomes not fully separating at the time of differentiation of the fertilized egg, and is a congenital problem that cannot be cured. However, some of the symptoms can be treated. Infertility due to chromosomal abnormalities can be treated, as well as Crohn’s syndrome, which causes men to not be able to produce enough sperm, with little or no sperm in the testes, and thus infertility, and such men have normal sexual function, and can undergo in vitro fertilization through testicular sperm retrieval. There is no cure for chromosomal abnormalities because there is no way to change the chromosomes. Diseases caused by chromosomal abnormalities are mainly treated symptomatically, such as sexual function and fertility problems. Problems of sexual function can be treated with androgen supplementation or the use of PDE5 inhibitors. For fertility problems, if it is azoospermia, you can consider testicular biopsy sperm extraction or microscopic sperm extraction treatment, but the disease itself can not be cured.
