fertility treatment

Egg donation (IVF)

Q: My husband has two wifes. I have two sons while the other wife has no children. My husband is forcing me to give one of my eggs so that he can produce a test tube baby and put this in the uterus of the other wife. I am not happy with this. Is this allowed in Islam? 

Invitro Fertilisation (IVF)

Q: My husband and I have been trying to conceive for 6 years to no avail. We have seen specialists, been on medication, had surgery and have observed fasts and dhikrs, duas. We have been told by our current specialist that IVF (invitro fertilisation) is our last resort. We have read and heard from many sources that it is permissable as long as extra precaution is taken to ensure that the correct sperm and eggs are mixed to implant into the uterus, however we have also heard that this procedure may be haraam. Is this permissable, if carried out by an Islamic run fertility centre, under a Muslim fertility specialist. Your advise is highly appreciated. 

Women going to male doctors

Q: I have been married for two years and and we are trying for a baby from the beginning onwards but still there is no pregnancy due to which we went to a fertility clinic which was a female doctor. After investigation the doctor had instructed to perform HSG test for my wife, (it's a kind of test that they will insert some instrument into a women's genital and check inside for the blockage) and she also said that there is only one doctor to perform in the whole state but its a male doctor who is very experienced and aged around 75 years. My question is weather it is allowed in Islam to perform these kind of tests with a male doctor?
