One or more pre- embryos suspend in a drop of culture medium are drawn into a transfer catheter, a long, thin sterile tube with a syringe on one end. Gently, the doctor guides the tip of the loaded catheter through the cervix and deposits the fluid into the uterine cavity. One or more embryos may be transferred during this procedure. The doctor and patient make the decision to use cryopreservation in advance. The entire transfer procedure usually takes between 10 and 20 minutes.
Some doctors recommend bed rest after the transfer.
Pregnancy Rate Among all woman undergoing IVF in the United States in 1988, the rate of pregnancies resulting in live birth was approximately 12 percent per treatment cycle. The pregnancy rate varies from program to program and, from time to time, even within the same program. At present there is no single accepted national standard for computing pregnancy rates.
