Why does Turner syndrome cause periods to stop?

Periods Stopped is a common presentation of Turner Syndrome. Differences in the X chromosome can affect the ovaries, sometimes leaving them with limited follicles or reduced function. When ovarian hormone levels are low, the uterine lining may not follow the usual monthly pattern, and ovulation may not occur.

The timing and pattern vary. Some people do not start periods, while others have periods that become irregular and then stop. Turner syndrome can also affect growth, heart health, hearing, and other body systems, so menstrual changes are considered alongside the wider health picture.

Arrange an assessment with a healthcare professional experienced in Turner syndrome, such as a gynaecologist or endocrinologist. They may review your menstrual history, symptoms, medicines, and previous care, and may discuss hormone tests or imaging when appropriate.

Treatment is individualised. Hormone replacement may be discussed to support puberty, menstrual cycling, bone health, and other effects of low oestrogen. Do not start, stop, or change hormones without medical guidance. Keep a record of bleeding, pain, hot flushes, and any treatment you use.

Seek prompt medical advice if periods stop unexpectedly, pregnancy is possible, or stopping is accompanied by pelvic pain, unusual discharge, severe headaches, vision changes, or new breast symptoms. Seek urgent help for fainting, severe weakness, or bleeding that is rapidly soaking through pads.

Ask whether your menstrual pattern fits ovarian insufficiency related to Turner syndrome, whether hormone testing is useful, and how treatment could affect bones, fertility planning, and cardiovascular care. You can also ask which symptoms should prompt an earlier review.
