As a woman’s ovaries age, her ability to have children declines, while the risk for miscarriage increases. Some women experience early ovarian failure, leading to early menopause and higher risks for developing bone loss, heart disease, and memory problems.
Therefore, ovarian aging is not just a fertility issue but a major women’s health concern. Despite the profound effect of ovarian aging on women worldwide, we still don’t know exactly why it happens or if it can be prevented. In this study, Rho, working in the lab of Kutluk Oktay, MD, PhD, at Yale School of Medicine, will examine chemical changes, called methylation, in the BRCA1 gene to identify markers of ovarian aging. Then she will apply CRISPR technology, a gene-editing tool, to see if these changes can be reversed
“My research has focused on understanding why women’s eggs age and specifically, how changes in the epigenome — the molecular “software” that controls our genes — may cause the decline in DNA repair that leads to reduced fertility and earlier menopause. Ovarian aging affects every woman, yet we still do not fully understand why it happens or how to reverse it,” says Rho. “This research is deeply meaningful as it addresses a critical gap in women’s health research. For decades, we have focused on treating infertility, but not on preventing or delaying the biological causes behind it.”
"Women's life span has doubled within the last 150 years, yet the menopausal age has not changed. This results in women spending decades of life with consequences of ovarian aging which includes infertility, menopause-complications and altered quality of life,” says Oktay. “After my laboratory's discovery of declining DNA repair in oocytes as the main cause of ovarian aging, we are now poised to understand the mechanisms behind that decline. Dr. Rho is an extremely talented, hard-working, and dedicated scientist who will take on this project through sophisticated single cell and CRISPR technologies developed in our laboratory.”
