I have two daughters and I want to have boy twins by means of in vitro fertilisation. What is the Islamic ruling on that? Is it halaal or haraam?.
Praise be to Allaah.
If you cannot have children normally and you have turned to
artificial fertilisation – whilst paying attention to the guidelines on that
– in that case there is nothing wrong with trying to decide the gender of
the foetus, because of the permissibility of artificial fertilisation in
your case. See the answer to question no.
But if you are able to have children in the normal manner, it
is not permissible for you to resort to artificial fertilisation with the
aim of choosing the gender of the foetus, except in cases of necessity
having to do with hereditary diseases that affect only females and not
males, as stated in the resolution of the Islamic Fiqh Council. However, it
is permissible to follow natural methods of choosing the gender, such as
following a particular diet, chemical washes and choosing the time of
intercourse according to the time of ovulation, because these are
permissible means and there are no reservations concerning them.
