AIM: The aim of this study was to assess the quantitative and qualitative outcomes of assisted reproductive technologies in Italy, from 2005 to 2007, collected by the Italian Assisted Reproductive Technologies Register (IARTR).
METHODS: We analyzed, retrospectively, 121,708 ART treatments performed by Italian assisted reproductive technologies (ART) centres from 2005 to 2007.
RESULTS: In the study period ART Italian centers were reporting data to the IARTR. Number of total cycles (all homologous) reported was 121,708 including 110,074 fresh (FRESH), 8682 frozen/thawed oocytes (FO) and 2952 frozen embryo (FER). Pregnancy rates per cycle with respect to FRESH, FO and FER treatments were 19.1%, 10.2% and 15%, respectively. Delivery rate per cycle with at least one live birth was 10.8%, 5.8% and 8.4%, respectively, per type of procedure. Twin and "triplet or more" birth rate per delivery was 21% and 2.8%; 12% and 0.4%; 14.9% and 0.8%, respectively. During the study period 15923 ART infants were born (0.95% of all newborn in Italy).
CONCLUSION: From 2005 to 2007 we registered a strong increase in ART procedures concomitantly with a qualitative improvement leading to increased pregnancy and live birth rates per cycles. Remarkably, pregnancy loss to follow-up decreased drastically during the three years study-period.
