I am not sure if I would believe mini-ivf has a triple success rate of IUI becuase that is nearly the same success rate of IVF, but I am pretty unfamilar with it.
Micro-IVF usually costs around $3000-$4000, which is considerably cheaper than regular IVF. They use less medication during the process which produces less eggs for the procedure. They try to eliminate multiple birth pregnancies with this. I have only read a little about this, but I do know that they say the pregnancy rate triples from that of IUI. I have no idea what FSP is...if you find out, please let me know.
