Frozen Embryo Transfer Timeline

frozen embryo transfer timeline

how long does (FET) take tame?

A FET cycle will take approximately 6 to 8 weeks.

To avoid this problem, three to five days after egg retrieval, all embryos are cryopreserved. The next month or in the month after, when the endometrium has had a chance to form without the influence of ovarian stimulating drugs, a frozen embryo transfer can take place

Embryo freezing takes several hours while the thaw process takes about 30-45 minutes. Embryos have been successfully thawed after cryopreservation for as many as 13 years. Clinical pregnancies have been reported from embryos stored for 9 years.


How long does it take to complete a frozen embryo transfer cycle?

approximately 6 to 8 weeks
A FET cycle will take approximately 6 to 8 weeks. A cycle typically begins with 3 to 4 weeks of daily birth control pills to suppress the normal ovarian cycle, as it would lead to ovulation. After the course of birth control, you will need a baseline assessment involving bloodwork and ultrasound.

What is the procedure for frozen embryo transfer?

The Frozen Embryo Transfer procedure is simple. It involves thawing and then transferring the embryo into a woman’s uterus for hopeful pregnancy. Embryos are transferred to the uterus through a catheter. This procedure is much like a pap smear, does not require any anesthesia, and is usually painless

How long does it take to thaw a frozen embryo?

Embryo freezing takes several hours while the thaw process takes about 30-45 minutes. Embryos have been successfully thawed after cryopreservation for as many as 13 years. Clinical pregnancies have been reported from embryos stored for 9 years

What day of cycle is FET done?

The first ultrasound is usually performed on day 10-12. When the endometrium is thick enough and of the right maturity, a trigger injection is given to better effect ovulation and to change the endometrial receptivity. The embryos are then thawed for transfer

Do you ovulate during a frozen embryo transfer?

Frozen Embryo Transfer and Desynchronization in IVF
During the menstrual cycle, estrogen levels naturally peak just before ovulation. This rise in estrogen triggers ovulation and causes the ovaries to begin producing progesterone. Progesterone then triggers the development of the endometrial lining of the uterus

Are frozen embryo transfers more successful?

Any patient, no matter the amount of time between embryo freezing and thawing, can expect nearly the same potential for success as they experienced with the fresh IVF cycle that the frozen embryos came from. Women 35 years and younger have over a 60 percent chance of pregnancy per transfer

What happens in a frozen embryo transfer cycle?

A Frozen Embryo Transfer cycle is the process whereby a patient uses embryos frozen from a previous IVF cycle in a new cycle. It is performed in a unstimulated cycle and involves careful monitoring and preparation of the lining of the uterus (endometrium), ready for the transfer of frozen embryos.

When should I expect my period after embryo transfer?

Period type cramps are very normal during the period between your transfer and the pregnancy test, especially quite soon after an embryo transfer. You might also experience them approximately seven to 10 days after an insemination.

Do frozen embryos take longer to implant?

According to the researchers, the success of frozen embryos can be explained by the fact that frozen embryos take longer than fresh embryos to implant in the uterus. This is important because it allows hormone levels in the uterus to return to normal before the embryo is implanted.

Is bed rest necessary after embryo transfer?

When IVF first started, patients were rested strictly flat on their backs for 24 h. Subsequently embryo transfer became an outpatient procedure, with most women having only a few minutes rest. A study by Botta and Grudzinskas (1997) found that 24 h of bed rest after embryo transfer did not influence the pregnancy rate
