[Prognostic factors of pregnancy in intra-uterine insemination with sperm of donor: a review of 535 cycles over 7 years].

Aim: To determine the pronostic factors of pregnancy in intra-uterine insemination using sperm of donor (IIU-D) by analysing female factors, data from the ovarian stimulation and even the characteristics of the donor selected for the recipient couple.
Material and Methods: Retrospective study between January 2002 and December 2009. It took place at the University and Hospital of Amiens over 149 couples performing a total of 535 IIU-D cycles. Factors related to the pregnancy were defined thanks to uni and multivariate analysis.
Results: Female age was 30.6 ± 4.3 years old (6% of the cycles with women>38). The initiated pregnancy rate per cycle was 27.9%; the birth rate per cycle was 20.4% and the cumulative live birth rate over 63.4% for six cycles. In multivariate analysis prognostic factors of success were: day 3 of estradiol level less than 80 pg/mL (P<0.05), no tube defects (P=0.022), cured and benign womb pathology (P=0.005), a higher number of follicles greater than 16 mm the day of the ovulation triggering (P=0.0018) and a higher number of pregnancies already obtained by the donor in ART in the CECOS (P<0.001). Neither the female age nor the donor age was associated with a probability of success.
Discussion and Conclusion: Classical pronostic factors concerning the female profile and the ovarian stimulation quality have been found. But the most interesting and original part is that the most significant factor concerns the donor and his history of pregnancy in Assisted Reproductive Technology (ART) in the center. This may be very useful to guide the choice of the donor for the recipients.
