IVF in the news again

Another day, another IVF scare story... or at least that's how it sometimes feels.  We're forever being told that this procedure or that type of treatment is risky for us or our future children.  It's not always easy to make sense of what lies behind the headlines or to decide what might be best for you.

The latest story claims that fertility clinics are putting profits before women's safety by opting for traditional rather than mild IVF, which involves lower doses of drugs.  The safety aspect appears to focus on ovarian hyperstimulation, a condition that occurs if the ovaries become over-stimulated after using fertility drugs. Ovarian hyperstimulation can be very dangerous, but specialists usually have an idea of which women are particularly likely to be at risk before they start treatment and tailor drug doses accordingly.  Once fertility drugs are being administered, regular scans can give an idea of situations where the ovaries are starting to respond too strongly - and in these cases treatment is normally halted, at least for a while.  So yes, of course ovarian hyperstimulation is a risk of fertility treatment, and yes, of course you may want to talk to your fertility specialist about how they ensure the dangers are reduced - but don't be completely panicked by another scare story.

Whatever the rights and wrongs of mild IVF,  today's stories go far beyond that.  One talked about the "toxic" drugs used in fertility treatment in the UK and made it sound as if we use completely different, old-fashioned dangerous drugs here when everyone else in the world is using some kind of safe, modern drug. It's simply not true. Talk to your consultant, talk to your doctor or fertility nurse, talk to your counsellor - then make the decisions that are right for you - and take your daily paper with a pinch of salt!

IVF risks

If you'd read some of the newspaper headlines about IVF this morning, you could be forgiven for getting into a bit of a panic. It sounded as if going through IVF put you at a hugely increased risk of having a baby with Down's syndrome, and that it was the drugs used during fertility treatment which caused the problem.

This research is undeniably interesting, but it's far from conclusive. The eggs of just 34 couples were examined, far too few to be truly representative, and the reason for the problems they found is not clear either. They saw that when older women took higher doses of fertility drugs during treatment, there were abnormalities in the eggs which were produced. These abnormalities appear to be different from the more common problems which occur in older women's eggs anyway.

There are a number of things that need to be understood about this. The eggs studied were far more likely to lead to an unsuccessful treatment cycle or a miscarriage than to a baby with serious problems. The researchers have suggested that ovarian stimulation could disturb the normal process of egg production, but it is also not clear whether the fertility drugs caused problems for the eggs or whether the treatment allowed eggs to be produced from the ovaries which might otherwise never have got as far as being released.

So, we would like to see more research in this field to discover whether pushing older women's ovaries to produce more eggs actually only results in larger numbers of poor quality eggs - but in the meantime you can find out more about the research at www.eshre.eu
