Is it permissible to take drugs to suppress sexual desire in order to devote oneself to seeking knowledge and serving religion, especially given the inability to marry and the mental preoccupation with women?

The best way to reduce desire is frequent fasting. If desire is not curbed by this, then there is no harm in consulting a doctor for medication that alleviates it without eliminating it entirely, because that is impermissible, as it is a form of castration. It is disliked to resort to stratagems to eliminate desire. However, if the medication eliminates it entirely, it is forbidden, and it is disliked if it only weakens it.
