From Cancer to Motherhood

Today’s guest post is a subject very close to my heart. Special thanks to Dr Sonja Kristiansen MD, a board certified Reproductive Endocrinologist Infertility (REI) specialist, for providing us with her expert advice.

As an OB/Gyn resident, my career was transformed by the habit-forming experience of a new mom-to-be’s smile — especially since she thought that day would never come.

For many women with cancer, dreams of motherhood can be heart-breaking. Frequently they must choose between life-saving chemo and radiation therapies or a chance at becoming a mother. I’ve heard them talk about how time seems to move faster when so many difficult and final choices are on their shoulders.

What I do is about more than just baby-making. For women with cancer, reproductive medicine represents not just surviving a disease, but going on to have a fulfilling life.

There are options to preserve fertility prior to undergoing cancer treatment. It’s important for patients to understand this fact up front, because they’ll often have to advocate for themselves. Oncologists are focused primarily on saving the life of the person in the exam room, not so much their potential offspring.

The successful use of frozen sperm is many decades old, going back to the 1950’s, but the pace of technology picked up great speed about 30 years ago, from the first in vitro fertilization (IVF) birth in 1978 to 1983 when the first child who resulted from a frozen embryo was born. More firsts quickly followed: the use of another woman’s egg cells (donor eggs) and gestational surrogates, the ability to select a single sperm and inject it into an egg (intracytoplasmic sperm injection, or ICSI,) the ability to preview an embryo in vitro and determine its viability before transfer to the womb (preimplantation genetic diagnosis, or PGD.)

Each of those technical advances was met with worry — by physicians, patients, and the general public. Today’s questions swirl around oocyte cryopreservation, or egg freezing.

In 1997, the first US baby was born from a frozen egg cell that had been thawed, injected with a sperm cell for fertilization, and the embryo then transferred to the mother. In 2006, the first cancer survivor used her eggs, frozen prior to chemotherapy, to have a biologically-related child with the help of a gestational surrogate.

Still, many fertility experts are slow to embrace the technology. Some simply do not offer it to any patient, whereas others have policies that determine which patient can access the treatment.

Oocyte cryopreservation is a simple concept with tremendous potential in both application and implication. And it is not the only option — some patients may opt for IVF or intrauterine insemination after cancer surgery but before chemo or radiation. Many choose to use IVF to create and freeze embryos for use down the path, after they’ve been cleared by their oncology team.

All of the fertility preservation options allow women cancer-survivors to move on to fully reproductive lives. If your oncology team doesn’t mention the topic of future pregnancy, bring it up yourself.
