When considering a hysterectomy, many women believe that keeping their ovaries will protect them from early menopause. However, recent research suggests otherwise. Even when the ovaries remain intact, hysterectomy can significantly impact hormonal balance, leading to earlier ovarian decline and menopause. Understanding these changes is crucial for making informed health decisions.
How Hysterectomy Affects Hormones
A comprehensive 2023 meta-analysis examined 14 studies involving over 1,400 premenopausal women and found significant hormonal changes in those who underwent hysterectomy while preserving their ovaries. Key findings include:
-
Lower Anti-Müllerian Hormone (AMH) Levels: AMH is a marker of ovarian reserve. Women who had a hysterectomy showed a more rapid decline in AMH, suggesting decreased ovarian function.
-
Higher Follicle-Stimulating Hormone (FSH) Levels: Elevated FSH indicates reduced ovarian activity and is a hallmark of perimenopause and menopause.
-
Lower Inhibin B Levels: This hormone helps regulate FSH. Its decline further signals diminishing ovarian function.
-
Higher Luteinizing Hormone (LH) Levels: Increased LH is another marker of ovarian aging and hormonal shifts.
-
Estradiol (E2) Levels: While trends showed a decrease in estrogen levels, the change was not statistically significant.
Why Does This Happen?
The exact reason why ovarian function declines more rapidly after hysterectomy is still under investigation. However, researchers suggest a few potential factors:
-
Disrupted Blood Flow: The uterus and ovaries share a blood supply. Removing the uterus may reduce blood flow to the ovaries, leading to earlier dysfunction.
-
Inflammation and Surgical Stress: Surgery itself can trigger inflammatory responses that may accelerate ovarian aging.
-
Loss of Uterine-Ovarian Communication: Emerging research suggests that the uterus and ovaries communicate through hormonal and nervous system pathways, and removing the uterus could disrupt ovarian function.
What This Means for Women Considering Hysterectomy
While hysterectomy can be a necessary and beneficial procedure for many women, it’s important to be aware of the potential hormonal consequences, even if the ovaries are preserved. Women over 40, in particular, may be at higher risk for earlier ovarian decline.
If you’re considering a hysterectomy, discussing the following with your healthcare provider can help you make an informed decision:
-
Hormonal Monitoring: Regular testing of AMH, FSH, and other key hormones can help track ovarian function post-surgery.
-
Menopausal Symptom Awareness: Even if menopause doesn’t occur immediately, being aware of early symptoms such as hot flashes, mood swings, and fatigue can help with early intervention.
-
Potential Preventative Strategies: Lifestyle modifications, hormone therapy, or other medical interventions may help mitigate some of the effects.

The belief that keeping your ovaries after a hysterectomy fully protects against early menopause is being challenged by emerging research. While every woman’s experience is unique, staying informed about potential hormonal shifts can help ensure better long-term health and well-being.
