LONG &  SHORT IVF PROTOCOLS

Dear doc

How are you?

Please explain the difference in IVF protocols. Is it possible to use the same injections and meds as one would use for IVF, but try naturally? We have had several IUIs which failed and have been told that IVF may be better. However, it is so expensive.

Dear Mia

Long and short IVF protocols usually would give the same success rates except that few injections are used in the short protocol than the long protocol. In the long protocol down regulation is started about a week before the commencement of follicular stimulatory drugs. You may require up to 3 weeks of injection in the long protocol. In the short protocol an antagonist drug is used to control premature ovarian surges. The duration of treatment usually does not exceed more than 12 days of injections. The costs of both these cycles are very similar except the short cycle being just slightly more occasionally, depending on the number of drugs used. Trying a natural IVF cycle would mean using no injection, so I am uncertain as to what your question entails. If you want to use the injections used for IVF but try natural conception then that may not be a very cost effective way as the drugs are quite expensive to try a natural cycle. However using a natural cycle for IVF is possible and the cost of that would be significantly lower than an IVF cycle. However it needs to be remembered that this lower cost usually means a lower success rate and possibly cancellation of cycle as maximum of two follicles are usually obtained in a natural cycle.
