Fertility Preservation

Focusing on your today, without giving up on your tomorrow.

Having your fertility threatened by a medical condition or treatment can be devastating. But, there is hope.

Many medical conditions or their treatments can negatively impact your fertility. We work with you and your specialists to preserve your fertility so that you can still build the family of your dreams in the future.

About Fertility Preservation

Fertility preservation is the process of freezing eggs or sperm now to make it possible to conceive in the future.

Many medications and procedures can have a significant and lasting effect on fertility for people with ovaries or sperm. For example, medications used to treat cancer like chemotherapy can have a devastating effect on eggs and can even put someone into premature menopause.  With Egg Freezing (oocyte cryopreservation), we can freeze a cohort of eggs prior to starting these treatments so as to maximize your chances of a healthy pregnancy in the future.  The same is true for those who produce sperm. With Sperm Freezing, we can freeze sperm (sperm cryopreservation) prior to starting treatments to maximize your opportunity of having a child in the future using your own sperm.

Fertility preservation is also an important consideration for those who are about to undergo hormonal treatment or surgery for gender-affirming care.  With current technologies, you can proceed with necessary medical treatments while ensuring the to use your own eggs or sperm when you want to build a family.

Fertility preservation can apply in the following circumstances:

It was only a few years ago when a cancer diagnosis might have meant the end of your ability to conceive using your own eggs. Today, we can safely preserve your fertility for building your dream family when you're ready.

Your Fertility Preservation Journey for Those with Ovaries Starts Here

This is a typical journey through fertility preservation for someone with ovaries. We know that the process can be overwhelming.  We will be by your side every step of the the way. The complete cycle takes approximately two to three weeks.  Fertility preservation for someone with sperm is a relatively straightforward process and can booked conveniently when ready.


The first step is to determine whether egg freezing is the right approach given your personal circumstances, medical history, and goals. We will often also reach out to your specialists to ensure that they feel you are a good candidate for fertility preservation. 

Meeting your Care Team

Your dedicated care team will provide you with appropriate and timely instructions so that you feel in control.  You will complete consent forms and participate in an education session where you will learn how to administer medications.  This is also a good time to ask questions.  

Ovarian Stimulation (10-12 days)

Stimulating your ovaries to produce eggs typically lasts 10-12 days. During this time you will be taking injectable medications and you will have three to five in-person morning appointments at the clinic where we will monitor your hormones and measure your ovarian follicles using vaginal ultrasound.  Your physician will closely monitor your stimulation to ensure the optimal number of eggs.

Egg Retrieval (~Day 12)

Prepare to spend one to two hours at the clinic on the day of egg retrieval.  You will also need to arrange for someone to pick you up.  The egg retrieval itself is done under deep sedation with an anesthesiologist to ensure your safety and comfort.  The procedure lasts approximately 20 minutes.  You may experience minor discomfort after the procedure. Most patients resume normal activities the next day.

Post Egg Retrieval

After the retrieval, your eggs will be evaluated and frozen by our expert embryologist team using a technique called vitrification.  Our embryologists will speak with you before you leave and review the quality and the number of eggs.  Your eggs will be kept in a secure environment for storage until you need them.
