Embryo Freezing: What to Expect

Embryo freezing (also known as embryo cryopreservation) is an advanced fertility treatment that allows individuals or couples to preserve embryos for future use, whether for family planning, medical reasons, or to safeguard fertility for a later time. As part of the fertility preservation process, the preparation is crucial for ensuring the best possible outcome. This blog post will walk you through what to expect when preparing for an embryo freezing cycle, including both male and female testing, as well as how Elsa Fertility helps make the process smoother and more affordable.

What is Embryo Freezing?

Embryo freezing is a process where embryos created through in vitro fertilization (IVF) are frozen and stored for future use. This can be an ideal option for those wanting to delay pregnancy or individuals undergoing medical treatments, like chemotherapy, which may affect fertility. Once you're ready, the embryos can be thawed and implanted into the uterus, offering a reliable way to start a family when the time is right.

Step 1: Pre-Cycle Preparation for Women

Before the embryo freezing cycle begins, women will undergo several preparatory steps. These tests are essential in evaluating the health of your reproductive system and determining the best approach for stimulating egg production.

Lab Testing

The first step in your fertility journey is understanding your ovulatory cycle. An initial consultation with a reproductive endocrinologist (REI) is vital for assessing your overall fertility health. This might involve blood tests to check hormone levels, such as estradiol, FSH (follicle-stimulating hormone), and AMH (anti-Müllerian hormone), which give insight into ovarian reserve.Additionally a CBC, CMP, and Infectious Disease Panel is generally drawn to ensure your health prior to undergoing any treatment.

Ultrasound Evaluation

A pelvic ultrasound will also be performed to evaluate your ovarian health, assess the number of follicles present, and check for any structural abnormalities in the uterus or ovaries. This will help your REI understand the best approach to ovarian stimulation.

Genetic Testing

Genetic carrier screenings are done to check for any hereditary conditions or chromosomal issues that could affect your embryos. This is particularly important for women in higher age groups or those with a known family history of genetic disorders. This test can be easily completed at home in most cases via a saliva sample that is shipped to a lab for evaluation. Any abnormalities will be discussed with a genetic counselor.

Preparing for Ovarian Stimulation

Once these tests are complete, your REI will recommend a personalized ovarian stimulation protocol. You’ll begin taking hormone injections for about 10-14 days to stimulate your ovaries to produce multiple eggs. Monitoring through ultrasounds and blood work is done frequently during this time to track follicle growth and adjust medications accordingly.

Step 2: Pre-Cycle Preparation for Men

While embryo freezing is often associated with women, male fertility plays a critical role in the process as well. The male partner will also undergo a series of evaluations to ensure optimal sperm quality, which is crucial for creating healthy embryos.

Semen Analysis

The first step for men is to provide a semen sample. This is typically done in a private setting at the fertility clinic or at home with a home testing kit. The sample will be analyzed for sperm count, motility (how well the sperm move), morphology (the shape of the sperm), and overall quality. If sperm quality is a concern, your REI might recommend additional measures such as sperm washing or testicular sperm aspiration (TESA) for retrieving sperm directly from the testes.

Genetic Testing

Similar to women, men may also be recommended to undergo genetic testing. This could include testing for common genetic conditions like cystic fibrosis, or chromosomal disorders that could impact the fertility treatment process or the health of the embryo

Sperm Freezing

If you’re not ready to provide a fresh semen sample during your IVF cycle or if sperm collection might be difficult due to medical reasons, sperm freezing (also known as sperm banking) is an option. You’ll provide a sperm sample that will be frozen and stored for later use.

Step 3: What to Expect During the Cycle

Once both partners have completed their testing and your ovarian stimulation is underway, you’ll continue with regular monitoring to track your response to the medication. For women, this means regular ultrasounds and blood tests to evaluate the growth of follicles. The timing of egg retrieval is crucial for ensuring that the eggs are mature and ready for fertilization.

On the day of egg retrieval, a needle is used to collect mature eggs from the ovaries, which are then fertilized with the male partner’s sperm in the lab. Once the embryos develop, they are frozen for future use.
