Why hysteroscopy before IVF is not a good idea



Lots of IVF clinics routinely do a hysteroscopy prior to doing IVF . They justify this because they say it's important to have a normal uterine cavity in which to transfer the embryos, and that a hysteroscopy is the best technique available to ensure that the cavity is normal.  They claim that this is a simple procedure, which involves doing minimally invasive surgery , and if by doing this they can increase the chances of pregnancy for even one patient by picking up a problem which would otherwise have been missed, they are justified in doing so.

I do not agree. I think doing a hysteroscopy routinely prior to IVF is practicing mindless medicine – and while cookbook medicine can be profitable for large clinics, it’s rarely in the patient’s best interests.

I agree it’s good for the doctor. Doctors like doing procedures , because they get paid for doing them ! The question is – is it worthwhile from the patient's perspective ?

The truth is that if a vaginal ultrasound scan shows that the endometrium is trilaminar, thick and normal, the chances of finding anything abnormal on the hysteroscopy are extremely low . If the doctor wants to be doubly sure, he can do a sonohysterogram to visualize the uterine cavity even more clearly.

The point is that if we can get the information we need by doing a simple, cheap and noninvasive test, then how are we justified in doing a surgical procedure ? ( The word minimally invasive is a clever oxymoron invested by a smart surgeon – it’s a bit like saying some one is a “little pregnant” ! For the doctor, this might be a minor procedure, but for the patient, every medical procedure is “major”.)

Tests should be tailored to meet the needs of individual patients , and hysteroscopy should be reserved for patients where the ultrasound scan is abnormal or difficult to interpret.

The irony is that if the hysteroscopy result is normal ( as it usually is !), then instead of feeling bad that he subjected the patient to an unnecessary surgical intervention, the doctor is very pleased because he can now tell the patient – your hysteroscopy was normal, which means your chances of getting pregnant are very good ! The poor patient does not even realize that she was subjected to unnecessary surgery !

It’s true that a hysteroscopy can be useful prior to IVF, but it should be used selectively . Thus. when the ultrasound scan result suggests there is an abnormality, a hysteroscopy allows us to confirm the diagnosis , and treat it as well.

The danger of routine hysteroscopy is that doctors have “itchy fingers”. When they insert the telescope inside the uterine cavity, they will often “find” problems ( of no clinical importance, because they are just normal variants) , which then they will “ treat” . This has the benefit that it allows them to charge even more. The downside is that doctors will then do a “metroplasty” or treat a “ subseptate uterus”, but this kind of unnecessary surgery can reduce the patient’s fertility , by causing scarring and adhesions.

If your doctor advises you to do a hysteroscopy prior to doing IVF, you should push back and ask – How will this change my IVF treatment plan  ? and is it possible to get this information by doing a noninvasive test ? Unless patients take the initiative and invest in Information Therapy to protect themselves, we will continue to see lots of unnecessary hysteroscopies being performed.
