[The follicular flushing duplicate the pregnancy rate on semi natural cycle IVF].
OBJECTIVE
To evaluate the importance of follicular flushing on semi natural cycle IVF.


METHODS
We have compared prospectively the reproductive potential of oocytes obtained from follicular fluid (LF, N = 79) to those obtained from follicular flushing (R, N = 47) in 146 oocyte pick ups.


RESULTS
The group LF and R were similar with regard to fertilization rate (79.7 versus 88.1%, respectively), percentage of superior grade embryos (28.8 versus 37.8%) and implantation rate (24.1 versus 44.1%).


CONCLUSIONS
The practice of follicular flushing on semi natural IVF cycle improves the pregnancy rate. The oocytes obtained by follicular flushing had the same reproductive potential than those obtained on follicular fluid.
