Transferring embryos to the uterus Embryos are transferred to the uterus through a small tube, or catheter. This procedure is much like a pap smear and does not require any anesthesia and is usually painless. The embryos are placed in a small amount of fluid inside the catheter, which is passed through the cervix at the time of a speculum examination. The embryos are placed in a manner so they reach the top part of the uterus. The number of embryos transferred depends on individual circumstances of the couple and this decision will be made collectively by you, your physicians and the embryologist, two to four embryos may be transferred in one treatment cycle.
Embryo transfer can cause mild cramping.
There is a small risk of bleeding or infection as a result of the transfer procedure. After transfer, the woman may get dressed and leave after a brief rest. A pregnancy test will be done 12-14 days after the transfer regardless of whether you have had any uterine bleeding. The transfer of several embryos increases the probability of success. If you do not make arrangements for embryo transfer at the time recommended, your chances for pregnancy could decrease.
