Estrogen and progesterone play a significant role in the growth of uterine fibroids. Both hormones are naturally produced in higher amounts during a woman’s reproductive years, which explains why fibroids commonly occur between ages 25 and 50 and tend to shrink after menopause.
- Estrogen’s Role: Estrogen promotes the growth of fibroid tissue, especially during menstrual cycles. When estrogen levels are high, fibroids tend to grow more quickly, which is why they often enlarge during pregnancy and shrink after menopause when estrogen levels decline.
- Progesterone’s Influence: Progesterone also stimulates fibroid growth, though it has a more complex role. While it can contribute to fibroid growth, some progesterone-based therapies can actually help control symptoms, like reducing heavy menstrual bleeding.
- Hormone Therapy: Hormonal treatments, such as GnRH agonists, are often used to lower estrogen levels temporarily, shrinking fibroids. However, these treatments are not long-term solutions due to side effects and risks associated with prolonged hormone suppression.
Understanding hormonal influences is key to determining effective treatment, particularly for premenopausal women who may require therapies to manage symptoms until natural hormone levels decline with age.
