Evolución y resultados de la transferencia de un embrión en un programa de donación de ovocitos

The progressive increase in the proportion of single embryo transfer becomes more noticeable when the SET criteria are followed, leading to a considerable, albeit still insufficient, decline in the multiple gestation rate. The cumulative results obtained contribute to the gradual degree of acceptance and safety of single embryo transfer and endorse its performance in good-prognosis patients.
