A recent study has illuminated the impact of reproductive ageing on the effectiveness of fertility treatments, particularly highlighting the challenges faced by women over the age of 49. Presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE), these findings underscore the complexities surrounding donor egg treatments and their implications for women seeking to conceive later in life.

Dr. Beatrice Crestani, a prominent researcher in the field, conducted the study which analysed the outcomes for 1,774 women undergoing fertility treatment. The results revealed a marked decline in success rates for those in their late forties. Specifically, women at the age of 49 and older have double the risk of miscarriage and encounter greater difficulties in achieving pregnancy. According to Crestani’s research, while donor eggs can improve the chances of conception, they cannot entirely counteract the effects of reproductive ageing.
Comparative statistics from the study illustrate this point vividly. Women in their mid-to-late thirties have a 54% chance of falling pregnant using donor eggs and IVF, whereas their counterparts aged 49 and above see that figure drop to approximately 43%. Furthermore, live birth rates also decrease significantly, from 46% for younger women to just 32% for those in the older category. Miscarriage rates also climb, rising from 24% to 28%.
Dr. Crestani noted that although these statistics may seem daunting, they should not deter women from considering donor egg treatments. “These findings should not discourage women from pursuing donor-egg treatment, as success rates remain meaningful even at advanced ages,” she stated. Nonetheless, she cautioned that patients must be aware that donor eggs do not fully negate the effects of ageing, and the challenges become more pronounced for women beyond 49 years.
In light of the study, British journalist Sharon Marshall shared her personal experiences with fertility treatments and the emotional toll of her journey. At the age of 46, she welcomed her daughter Betsey after a lengthy and often painful struggle with IVF. Reflecting on her journey, Marshall described her forties as a time fraught with illness and depression, which left her feeling a profound loss of autonomy over her own body.
Marshall’s candid account underscores a key issue: while celebrities who give birth later in life are frequently celebrated, the public often remains unaware of the difficulties they may have faced along the way. “We look at celebrities who have given birth in their late forties, early fifties and beyond. We celebrate them,” she observed, “but we don’t know what hell they’ve been through.”
Her own experience included six years of IVF attempts, within which she faced two pregnancies ending in loss prior to the eventual birth of her daughter. Marshall courageously shared, “Let’s be honest with women about the difficulties they may face, about how hard it can be to get pregnant when you get older. We deserve to know that.”
The intersection of age, reproductive health, and societal expectations shapes a complex landscape for women considering motherhood later in life. The insights from both Dr. Crestani’s research and Marshall’s narrative serve to highlight the importance of candid and realistic discussions surrounding fertility options and the potential hurdles that lie ahead.
As reproductive science advances, it remains crucial that medical professionals continue to provide comprehensive guidance to women of all ages. Understanding the limitations of donor egg treatments in relation to reproductive ageing may empower women to make informed decisions about their fertility journeys.
