He has breasts which resembles those of a woman
Question

A person has breasts which resemble a woman’s breasts. Is it permissible for him to have surgery to reduce them?
Praise be to Allah.We asked Shaykh ‘Abd-Allaah ibn ‘Abd al-Rahmaan al-Jibreen the following question:
 A person has breasts which resemble a woman’s breasts. Is it permissible for him to have surgery to reduce them?
 He (may Allaah preserve him) replied as follows:
 You must try to lose weight, then the fat around the breast will be reduced.
 If what you have is not a result of fat (and it is causing you trouble), and you can do an operation to reduce it without any harm involved, that will be OK.
