Reiterative changes in the Italian regulation on IVF: the effect on PGD patients' reproductive decisions.

National legislations represent one of the main factors influencing access to assisted reproduction treatment. The Italian situation in the last decade is an example of how the treatment of patients for preimplantation genetic diagnosis (PGD) was more dependent on regulators than on medical choices. This report analysed how the changes in Italian regulation affected the number of PGD referrals to this study centre, as well as their decision to opt for cross-border reproductive care (CBRC). The analysis showed that during the period in which PGD was actually not performed because of the restriction imposed by the Italian law on IVF (from 24 February 2004 to 7 May 2009) there was a significant decrease in the number of referrals asking for PGD (2.5% of total referrals) compared with the previous years (3.3%; P < 0.025) and following years when PGD was legalized (5.1%; P < 0.001). The number of couples opting for CBRC had an opposite trend, reaching a maximum when PGD was banned from Italian centres (55 couples), whereas after the readmission of PGD, only eight couples went abroad for treatment. Concomitantly, since May 2009, the proportion of couples performing a PGD cycle in this centre has constantly increased.
