[Prognosis factors in donor semen insemination: a 10-years follow-up study of 188 patients]

Improving our practice by a constant evaluation is essential in the field of donor semen insemination (DI). Our center examined the prognosis factors for DI success in order to standardize patient treatment options.

We retrospectively analysed all couples referred for DI from January 2000 till December 2010.

We analysed 551 cycles among 188 patients. Pregnancy rate by stimulation cycle was 19,8% with birth rate of 16.7%. The rate of pregnancy was improved till the fourth trial then plateau. On a patient-based analysis, success factors were age (P=0.04), previous successful DSI (P=0.02), and no previous failure of an ICSI-C (P=0.035). On a cycle-based analysis, success factors were the number of follicles greater than 15mm (P=0.04) and than 18mm (P=0.001). The percentage of 68.1 patients obtained a child by IVF-D after a failed DI.

There are two predictive factors for DI success: the age of the patient and the number of mature follicles. It seems accurate to referred patients to IVF-D after four unsuccessful cycles of DSI. This recommendation may be adapted according to patient's age and hormonal evaluation.
