Hi stillsunshine, I believe that this protocol is still relatively new in Spore context, thus some specialist might not have encounter it?Sometime this week I posted a link of a 1986 abstract which summarized a study on this. You may like to have a look.
http://www.ncbi.nlm.nih.gov/pubmed/3571438
Cannot get hold of the full article but from the result, it stated this " Prior norethisterone treatment appears to be an effective and useful means of controlling the timing of the oocyte recovery in IVF treatment"
FYI: oocyte recovery is aka egg retrieval/collection ( based on my research online)
The article also stated that the treatment did not significantly affect the outcome of IVF.
Though the study can be small, I believe for the use of this med prior to IVF shd have been studied by many others. Medical practices are quite evidence-based.
From what I know, hosp will not initiate a change unless sufficient evidence is given to support a change in practice.
Btw, which hosp are u visiting? The forum runs too fast to capture everyone
Apologies for my long-windedness...
