Recent research indicates that the reproductive life span for women has increased by over two years. Traditionally, the medical community has advised that the best age for a person to safely conceive and carry a pregnancy is in their twenties, with fertility beginning to decline after 30. Pregnancies after 35 have often been labeled as “geriatric,” which can make those uncertain about their future plans feel anxious.
However, a new study published in the Journal of the American Medical Association may provide some reassurance. It suggests that the average reproductive years for women in the U.S. may have shifted from 35 to 37.1 years—a notable increase. This trend is believed to stem from a gradual rise in the average age of menopause, which has the effect of extending the reproductive life span and potentially making it easier for those in their mid to late thirties and beyond to conceive.
The study analyzed data over the past sixty years, focusing on both the average age of natural menopause and reproductive life span, with specific attention to factors relevant to American women. In recent years, there has been a decline in the U.S. birth rate—while the global population continues to grow, the Centers for Disease Control and Prevention highlights a consistent drop in birth rates for U.S. women in their twenties. Researcher Emily Carter from the Guttmacher Institute noted that more individuals are choosing to start families later in life, driven by increased education and career opportunities.
Data indicates that birth rates for women in their thirties and forties are on the rise, suggesting a growing number of individuals are considering parenthood later in life. Researchers found a dual factor contributing to the increase in reproductive life span: the average age of menopause has risen from 48.4 to 49.9 years, while the average age at which girls start their periods has decreased from 13.5 years to 12.7.
Dr. Mia Johnson, a certified gynecologist, explained to ABC News the significance of monitoring these trends, as they could have broader implications for women’s health. While extended reproductive years may lead to a decrease in cardiovascular disease risk, they could also heighten the likelihood of hormonally responsive cancers such as breast, ovarian, and endometrial cancer. The longer the body produces reproductive hormones, the higher the potential risk for these conditions, Dr. Johnson noted.
Of course, the longer you experience menstruation means more time dealing with the associated symptoms, including mood swings, cramping, and fatigue. This extended timeline might also lead to a longer transition into menopause, which can come with irregular bleeding, sleep pattern changes, and hot flashes.
As with any gynecological or reproductive health concern, it’s wise to consult with your doctor to ensure your health is on the right track. Yet, there is comfort in knowing that you may have more time and options available to you.
