[Pregnancy predictive factors in case of double embryo transfer during "Top Quality" attempts].

Objectives: To identify IVF±ICSI pregnancy predictive factors during "Top Quality" attempts in case of double embryo transfer.

Patients And Methods: Three years retrospective study (2007, 2008 and 2009) on parameters and results obtained during IVF±ICSI defined as "Top Quality" attempts: first or second attempts on less than 35years old women (age inferior or equal to) with one or two "Top Quality" embryo transfer.

Results: In case of double embryo transfer, pregnancy predictive factors are (OR [IC 95%], P): average endometrial thickness on start (4.6 [2.9-5.5], P<0.01), women smoking (4.2 [3.5-4.9], P<0.01), average stimulation duration (3.4 [2.7-3.9], P<0.01), average men age (2.2 [1.7-2.5], P<0.05), gonadotrophins total dose (2.1 [1.1-3.2], P<0.05) and first rank's attempts (1.6 [1.2-2.5], P<0.05).

Discussion And Conclusion: Age patient, rank attempts and quality embryo are criteria, which used to guide to a single embryo transfer. Our results incite us to consider other parameters, in particular men age and women smoking status.
