While most girls with Turner syndrome experience primary amenorrhea (absence of periods), approximately 15-20% do have spontaneous menarche (the onset of menstruation). This means that a minority of girls with Turner syndrome will naturally start their periods.
Understanding Turner Syndrome and Menstruation
Turner syndrome is a condition characterized by ovarian dysgenesis, which affects the development and function of the ovaries. This typically leads to:
- Delayed Puberty: Many girls with Turner syndrome experience a delay in the onset of puberty.
- Primary Amenorrhea: Most do not start having menstrual periods on their own.
However, the reference indicates that not all girls with Turner syndrome have primary amenorrhea.
Spontaneous Menarche in Turner Syndrome
The fact that 15-20% of individuals with Turner Syndrome have spontaneous menarche highlights:
- Variability: There is a spectrum of severity and impact of Turner syndrome, with some experiencing more ovarian function than others.
- Possible Fertility: Spontaneous menarche can sometimes mean a greater chance of some ovarian function, though it does not guarantee fertility.
Summary of Menstruation in Turner Syndrome
| Feature | Description |
|---|---|
| Primary Amenorrhea | Most common, no spontaneous periods start. |
| Spontaneous Menarche | Occurs in 15-20% of girls with Turner Syndrome; periods start naturally. |
| Ovarian Dysgenesis | A condition where the ovaries do not develop properly, a main feature in Turner Syndrome. |
In conclusion, while it is less common, some girls with Turner syndrome do have periods.
