Official Title: Does Follicular Flushing Improve the Outcome in Monofollicular IVF Therapy?
Brief Summary: Follicular aspiration as well as follicular flushing are standardized techniques and have been practiced in polyfollicular IVF (in vitro fertilization) therapy for years. Monofollicular IVF therapy is a standard technique as well. IVF can be done in natural cycles or with a minimal stimulation with clomifen citrate to achieve a monofollicular response. Our study aims to compare follicular aspiration and follicular flushing in monofollicular stimulation. First the investigators want to answer the question whether flushing is beneficial for the oocyte yield. In case of a positive result the investigators want to establish a recommendation about the optimal number of flushings taking into account the duration of the procedure and the pain during manipulation.
