The Authors describe the A.R.T. echoguided techniques, that can be routinely used in IVF/ET programs. All these techniques are simple and have replaced the previous ones. The echoguided oocyte recovery is now widely accepted instead of the laparoscopic way: the gamete intrafalloppian transfer can be easily performed under local anesthesia; the selective fetal reduction in cases of multiple pregnancies can be easily carried out on an outpatient basis.
