Innovative Procedure Helps Women Preserve Fertility Even With Chemotherapy

While nursing Scarlett, her 5-month-old daughter, Heather Kokinda noticed a lump in one of her breasts. She decided to have it checked, but wasn’t really concerned.

“I thought it was a clogged milk duct,” she said. “When you’re 29, you don’t think it’s breast cancer.”

But it was. X-rays and a biopsy revealed the shocking news that the Seville, Ohio resident had Stage 1 breast cancer. “I went from feeling my life was perfect as a new mom, to the world crashing down around me,” Heather recalled.

By the time she began treatment with breast cancer oncologist Dr. Halle Moore at Cleveland Clinic Cancer Center, just two weeks later, the fast-growing disease had progressed to Stage 2. Because chemotherapy is the standard treatment for her type of breast cancer, and a common side-effect is ovarian failure, Heather knew the likelihood of having another child was slim.

“I came to terms with that,” Heather explained. “I had my daughter, and that was good enough for me.”

And yet, less than two years later, a healthy Heather is now the mother of two daughters. Scarlett’s sister, Josslyn, was born in July 2017 – thanks in part to a pioneering treatment Dr. Moore has helped spearhead that can protect the ovaries from the effects of chemotherapy.

Heather agreed to receive a drug called goserelin, a synthetic version of a naturally-occurring hormone, by monthly injections into the abdomen during chemotherapy. It temporarily suppresses the function of the ovaries, serving to protect them from premature menopause and infertility that can be caused by chemotherapy.

“Some young women are unwilling to take chemotherapy if their fertility will be impaired,” noted Dr. Moore, the lead author of a study on the effectiveness of goserelin that was published in the New England Journal of Medicine. “It can be quite dangerous to choose not to move forward, because chemo could vastly improve a patient’s likelihood of long-term survival.”

While women of child-bearing age also have the option of more traditional assistive reproduction techniques, such as storing embryos and eggs, these invasive and often expensive procedures can be an added burden while enduring cancer treatment. As Dr. Moore explained, the goserelin injections “provide women with another fertility option.”


Heather was 29 years old when doctors diagnosed her with breast cancer. In July 2017, she gave birth to Josslyn.

The study Dr. Moore led – the Prevention of Early Menopause Study (POEMS) – found patients who received goserelin during chemotherapy experienced just an 8 percent ovarian failure rate, about one-third the rate for the control group not receiving the treatment. Further, twice as many women gave birth after having goserelin treatments than those in the control group.

While Heather describes the four monthly injections as relatively painless, she did experience the typical effects associated with menopause while her ovaries were temporarily shut down. “Oh, I had hot flashes and everything,” Heather noted. “But it was worth it.”

While Dr. Moore recommends most women treated with chemotherapy wait at least two years before trying to conceive, to ensure they make it through the highest-risk period for an aggressive recurrence, Heather was pregnant about a year after completing chemotherapy, a double mastectomy and reconstructive surgeries.


An innovative procedure at the Cleveland Clinic helped Heather preserve her fertility while going through chemotherapy.

Now cancer-free, she and husband Jeremy are happily parenting two very active daughters. “The option to protect my fertility gave me the possibility to have another child,” Heather said, “without having to go through great lengths to do so. It’s pretty amazing.
