Pathogenesis (development of disease)
The interval between bleeding in polymenorrhea is less than 25 days, so bleeding occurs too often. This is often caused by follicular maturation disorders, sometimes with corpus luteum insufficiency. In biphasic cycles, follicular maturation is shortened. In monophasic-hypothermic cycles, aborted bleeding occurs.
Etiology (causes)
Biographic causes
- Hormonal factors
- Shortly after menarche (time of the first onset of menstruation).
- Shortly before menopause (time of the last menstrual period).
Behavioral causes
- Stress
Causes due to disease
- Disorders at the hypothalamic-pituitary level (hormone regulation in the brain).
