ICSI does not offer any benefit over conventional IVF across different ovarian response categories in non-male factor infertility: a European multicenter analysis.

ABSTRACT:

Purpose

To evaluate whether ICSI offers any benefit compared with IVF in different ovarian response categories in case of non-male factor infertility.

Methods

This is a retrospective multicenter analysis using individual patient data, conducted in 15 tertiary referral hospitals in Europe (1 center in Belgium and 14 in Spain). The study included the first cycle of all patients undergoing ovarian stimulation for IVF or ICSI in a GnRH antagonist protocol. Only patients having either IVF or ICSI for non-male factor infertility were included. Patients were divided into 4 groups based on their ovarian response as follows: group A, poor responders (1-3 oocytes); group B, suboptimal responders (4-9 oocytes); group C, normal responders (10-15 oocytes); group D, high responders (> 15
