Would the ruling on masturbation not change based on recent scientific research that proves its health benefits and refutes old concepts about its harms?

If a legal ruling is based solely on medicine, then the ruling changes with the change in medical knowledge, such as the prohibition of smoking after the discovery of its harms. However, the prohibition of masturbation is not based solely on physical harm, but also includes blocking avenues of desires except through marriage, based on His (Allah's) saying: (And those who guard their private parts. Except from their wives or what their right hands possess, for indeed, they are not to be blamed. But whoever seeks beyond that – then those are the transgressors). The prohibition also includes blocking the means to prevent desires from leading to unlawful acts, preserving the mind and body, and maintaining dignity, in addition to potential medical harms. Medicine is not the sole reason for the prohibition, and claiming health benefits for masturbation requires rigorous scientific research.
