The health risks from IVF, when preparing the uterus to accept a fertilised egg, are rarely disclosed. Both my daugters underwent this process and suffered awful side-effects. One daughter's liver was badly affected and she had to receive treatment to control the massive dose of hormones that threatened to overwhelm her liver, causing her to be very ill throughout her short pregnancy of 30 weeks. Her premature babies were delivered at the earliest time so she and her babies could start to recover, which was thankfully quick. They are all fine.
Additionally, the ethical issue of donating harvested eggs is a burden many couples going through IVF don't expect to face. If they don't have success immediately, one way to avoid expensive payment for further rounds of treatment is to donate eggs. My daughters chose not to because they could not bear the thought of their potential child being anywhere eise but with them, but if they had not been successful first time, they might have had to change their minds. Both said they would be wondering about those potential children and whether they would want to find them.
I'll watch this programme. I want to know how these women cope, even though they are only providing the means of incubating fertilised eggs. Many western women who have been surrogate mothers have kept the babies, even when the eggs were donated by a third party. It must be very diffcult for some women to bear another woman's child and hand them over. Couldn't do it myself.
