The Ruling on Artificial Insemination Between Spouses

Question:
Your Eminence the Shaykh! Peace be upon you and Allah's mercy and blessings. What is Your Eminence's opinion regarding what is called artificial thinning? It involves taking the husband's seminal fluid, adding chemical substances to it to stimulate the movement of the sperm, and then injecting it into the wife through a tube to increase the chances of pregnancy, if Allah wills?

Answer:
This matter has been discussed in the fiqh councils, and in reality, no definitive conclusion has been reached regarding it to date. The default ruling is prohibition and it is forbidden, because it involves exposing the private parts of the man and the woman without need or dire necessity. It also involves a lack of trust in the doctors who handle this, as something may enter into the lineage. This fluid may not be from this husband; something from another man's fluid may enter, because they are not always trustworthy. There may be someone among them who is unfaithful, so trust in the lineage is not established. Something may occur in this inherited lineage. Consequently, no reliable conclusion has been reached by the scholars of knowledge regarding this procedure to date, and the default ruling is its prohibition and that it is forbidden.
