Aspiration of endometrial cavity fluid at the time of egg collection

Abstract Aim To evaluate the efficacy endometrial fluid aspiration at the time of egg collection. Methods A prospective non-randomized pilot study of twelve infertile women who had ART (IVF-ICSI) at a University affiliated assisted conception unit. All women had persistent endometrial cavity fluid (ECF) in a controlled ovarian stimulation on the day of ovulation triggering. Results Following the discovery of ECF on the day of ovulation triggering, all women were counselled for the possible management options. None of these women had opted for the alternatives of freeze all or aspiration of ECF just prior to ET. In ten women ECF was aspirated at the time of egg collection. Five out the ten women in whom ECF aspiration was performed became pregnant (50%). Spontaneous resolution of ECF occurred in the remaining two patients; both became pregnant . Conclusions Aspiration of ECF at the time of egg collection is another new option for women with ECF. It obviated the need to freeze all or aspirate of ECF at the time of ET. It was associated with a good success andcan be a new convenient option in couples residing in low income countries. More studies are needed to establish the best management of ECF.
