Embryo Transfer

Quick Facts About Embryo Transfers

The final state of the in vitro fertilization treatment is known as embryo transfer, where the fertilized egg is placed in the woman’s uterus surgically.
The placement of the embryo is done with the help of a catheter that is inserted into the vagina to deposit the embryo into the uterus.

The transfer of the embryo takes place between day 3 and day 5 of fertilization for fresh transfers. The time period for frozen embryo transfers takes around 4 weeks.

There are various classifications of embryo transfers such as – fresh, frozen, cleavage (day 3), a blastocyst (day 5), single, and multiple transfers.
The standard practice is to have one embryo transfer at one time; however, two embryos may be transferred in some cases.

Embryos remaining from the IVF cycle are frozen for any future requirements.

What is an Embryo Transfer?

Embryo transfer is the final stage of the IVF process wherein mature eggs are retrieved from ovaries and fertilized by sperm in a lab. Then the fertilized embryo is then transferred to a uterus surgically. This procedure can be performed using a woman’s own eggs and the partner’s sperm. Or it may involve eggs, sperm, or embryos from a known or anonymous donor.

IVF and embryo transfer are required when natural fertilization is not an option, or the couple has difficulty with conception. There are many reasons for embryo transfer, including possible disorders of ovulation, anatomical disorders of the fallopian tubes, endometriosis, ovarian failure, fibroids, genetic disorders, and impaired sperm production of the male partner.

The process of an embryo transfer is similar to a pap smear, with the doctor using a speculum into the vagina to prevent the walls of the vagina from closing in. With the help of an ultrasound scan for accuracy, the doctor will then implant the embryo into the uterus with a catheter. The embryos are thus passed on from the catheter and into the womb.

The procedure is relatively pain-free and does not require any form of anaesthesia for completion.
