Is the husband's refusal to take the necessary fertility treatment, which he is capable of, considered a forbidden act? And does the wife have the right to demand a divorce as a result of his refusal to procreate and her evasion of the marital relationship because of it?

Islam has made procreation one of the most important objectives of marriage. Therefore, the husband should not refrain from seeking possible medical treatment that does not entail any Sharia prohibitions. However, it is not forbidden for him to abandon treatment. The wife is permitted to seek divorce due to infertility.
