In vitro fertilization (IVF) often involves a step called frozen embryo transfer (FET). With this, a frozen embryo is thawed and transferred to the uterus of the person carrying the pregnancy.
Let’s talk about what a frozen embryo transfer involves. This can help you prepare for a more in-depth conversation with your healthcare team and Progyny Care Advocate.
Getting ready for a frozen embryo transfer
There are a few ways to prepare your uterus for a frozen embryo transfer. Most of these approaches will involve blood tests and ultrasounds to monitor your hormones and uterine lining.
Your doctor will choose the approach that is best for you, based on your individual medical history and fertility goals.
Natural cycle
In a natural cycle, your own menstrual cycle is used to prepare the endometrium. (The endometrium is the lining of the uterus, which thickens during your cycle to prepare for implantation.)
No hormonal medicines are necessary, and the embryo transfer is timed to coincide with your natural ovulation. In a modified natural cycle, medicine is used to trigger ovulation.
Programmed cycle
In a programmed cycle, medicine (birth control or GnRH agonists) is sometimes given to suppress your own menstrual cycle so you don’t ovulate. In addition, estrogen and progesterone are used on a schedule to prepare the endometrium, and the embryo transfer is done at a precise time.
The transfer procedure
The embryo transfer is an outpatient procedure that doesn’t require anesthesia. Let’s talk about what to expect.
- Embryo thaw: On the day of the transfer, the frozen embryo is thawed under controlled conditions. The process is carefully monitored to protect the embryo.
- Getting ready: You may be asked to make sure your bladder is comfortably full. This helps create a straighter passageway into the uterus, and helps your doctor better see the uterus with an ultrasound while performing the transfer. You’ll lie on an exam table, similar to a Pap smear. A speculum is placed in the vagina.
- Embryo placement: The thawed embryo is placed in a thin, flexible tube by the embryologist. Your doctor will place the tube in the vagina, through the cervix, and into the uterus. Using an ultrasound for guidance, the embryo is then injected in the right location, about one centimeter from the top of the uterus. You can watch this happen on the ultrasound screen!
- What it feels like: Embryo transfers are generally not painful, although you may feel discomfort from the speculum. For some, though, it can be uncomfortable. Your doctor may prescribe medicine to help you relax, or rarely, anesthesia may be used.
- Recovery period: After the embryo transfer, you can empty your bladder and go home. You may have light spotting or cramping, although many people don’t feel anything. Read more about supporting your recovery after embryo transfer.
- Waiting for results: It’s recommended to do a pregnancy test with bloodwork 8 to 10 days after the embryo transfer. Your doctor will let you know the right timing for you.
Taking care of yourself before your transfer
The days and weeks leading up to your embryo transfer are an important time to focus on your health and well-being. Here are some evidence-based tips.
Healthy eating and nutrition
- Eat a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats.
- Avoid alcohol, recreational substances, vaping, and smoking. These can negatively affect fertility and pregnancy outcomes.
- Limit caffeine intake to less than 200 mg per day (about one 12-ounce cup of coffee).
- Take a daily prenatal vitamin that includes folic acid (at least 400 mcg) to support early fetal development.
Physical activity
- In most cases, you can continue your usual work and physical activities before a frozen embryo transfer unless your doctor gives specific instructions.
Stress and emotions
There’s no question: this can be a stressful period. Carve out time for stress management strategies, such as:
- Relaxation techniques (deep breathing, meditation, yoga)
- Light physical activity like walking
- Seeking support from friends, family, a counselor, or your Progyny Care Advocate
- Joining a fertility support group or using mental health resources offered by your clinic
