What to do when the sexologist recommends you to masturbate?

Question:

One of my brother of faith, who is 60 years old and who was left by his wife asked, “What should I do if the Sexologist recommended me to masturbate once a week to maintain the sexual functions of the body? What does the Bible say about this?

Masturbation is a sin and I recommend you to read some articles in which I explained this:

If the man you wrote about lives alone and has sexual desires at this age, the solution is either to refrain himself or to marry and not to masturbate.
