The short answer is no, you can’t have a period without ovaries: if both ovaries are removed (a procedure called bilateral oophorectomy), menstruation will stop. This is because the ovaries are responsible for producing the hormones estrogen and progesterone, which regulate the menstrual cycle.
Without these hormones, the body enters a state similar to menopause, and periods cease. This is often necessary for women with ovarian cysts, ovarian cancer, or those at high risk of cancer near menopause.
What Happens When Only One Ovary Is Removed?
When only one ovary is removed—a procedure known as unilateral oophorectomy—the remaining ovary typically compensates for the loss. If the remaining ovary is healthy and functions normally, it continues to produce hormones like estrogen and progesterone, which regulate the menstrual cycle.
The body adapts by relying entirely on the single ovary for egg production and hormonal balance. This natural adjustment often prevents noticeable disruptions in menstrual cycles, though some individuals may experience subtle changes, such as variations in cycle length or intensity.
It is crucial to monitor hormone levels and any shifts in menstrual patterns following surgery, as these can provide insights into how well the remaining ovary is functioning. Regular check-ups with a healthcare provider can help ensure that the hormonal balance is maintained, and they may recommend additional tests if irregularities arise.

Hormone Replacement Therapy (HRT) and Bleeding
For women who have had both ovaries removed or are in early menopause, hormone replacement therapy (HRT) is often prescribed. If the uterus is still intact, HRT can cause bleeding that may resemble menstruation.
This bleeding is not a true period but is triggered by changes in hormone levels, particularly if both estrogen and progesterone are part of the therapy. The timing and amount of bleeding depend on the HRT dosage and regimen.
Why You Should Consult a Gynecologist
Post-surgery bleeding can vary, so it’s important to discuss any unexpected bleeding with a healthcare provider. A gynecologist can help determine whether the bleeding is a normal side effect of HRT or if further investigation is needed. Monitoring hormone levels, adjusting medication, or considering alternative treatments may be necessary for optimal health management
