Praise be to Allaah.
Firstly:
There are different kinds
of fertilization, some of which are halaal and some are haraam. The halaal
types include:
(i)
Where the sperm is taken from
the husband and the egg from his wife, and fertilization is done externally,
then the embryo is implanted in the wife’s uterus.
(ii)
Where the husband’s sperm is
taken and injected into the wife’s vagina or uterus to fertilize the egg
internally.
The Islamic Fiqh Council
has stated that this is permissible. See the text of their statement in the
answer to question no. 23104.
Secondly:
It is not permissible to
keep eggs or embryos, and the fertilization of eggs must be limited to the
required number so as to avoid having an excess of fertilized eggs. If there
is an excess of fertilized eggs, they should be left without any care to die
naturally.
That is because keeping
embryos or eggs may lead to them being mixed with others as time goes by,
either by mistake or deliberately, as has happened in many cases. Some of
them may be taken and placed in the uterus of another woman, which leads to
confusion of lineages, which is a serious evil which outweighs the interests
which the couple may think are served by keeping embryos to save money and
use for fertilization later on.
The Islamic Fiqh Council
belonging to the Organization of the Islamic Conference has issued a
statement on this matter. The text follows:
1-
In the light of what has
happened of the possibility of keeping unfertilized eggs to be used later
on, when fertilizing eggs it must be limited to the required number for
implantation each time, to avoid an excess of fertilized eggs.
2-
If there are any extra
fertilized eggs – for any reason – they should be left without medical care
until they die naturally.
3-
It is haraam to use fertilized
eggs in another woman, and sufficient precautions must be taken to prevent
using fertilized eggs for an illegitimate pregnancy. End quote from
