Physical causes of the vagina not getting wet enough may be:
- Shortage of the hormone estrogen, for example by early removal of the ovaries.
- Neurological disorders e.g a heart attack, multiple sclerosis, anomalies of the nerves or the spinal cord.
- Certain types of cancer and their treatment.
- Certain medication.
- Getting older.
The doctor, gynaecologist or urologist can detect these physical causes.
