To evaluate the results of single embryo transfers, on a set of patients, for a given period of time. Between January 2008 and May 2010, we evaluated the results of all cycles with single embryo transfers in our workplace.
There were four groups of patients: the first group with elective single embryo transfers (ESET, n=147), the second group with only a single embryo transfer without selection (SET n=269), the third group with transfer of one embryo derived from the native cycle (NC, n=70) and the last group with transfer of only one embryo examinated by preimplantation genetic diagnosis (PGD, n=104). All patients were monitored by age, length of cultivation of embryos, clinical pregnancy rate / transfer (CPR / ET), pregnancy loss (AB) and baby take home rate (BTR).
Statistical evaluation was performed using the chi square test
