Study Arms (2)

Low aspiration flow rate

EXPERIMENTAL

All follicles will be aspirated with the addition of follicular flushing if necessary with an aspiration flow rate of 0.42ml/sec.

Procedure: Oocyte retrieval with low aspiration flow rate

High aspiration flow rate

EXPERIMENTAL

All follicles will be aspirated with the addition of follicular flushing if necessary with an aspiration flow rate of 0.62ml/sec.

Procedure: Oocyte retrieval with high aspiration flow rate

Interventions

All follicles will be aspirated with the addition of follicular flushing if necessary (up to 5 times per follicle) with an aspiration flow rate of 0.42 ml/sec.

Low aspiration flow rate

High aspiration flow rate All follicles will be aspirated with the addition of follicular flushing if necessary (up to 5 times per follicle) with an aspiration flow rate of 0.62 ml/sec.

High aspiration flow rate
