Overview
Classification
- The main classification of amenorrhea is based on the etiology, including primary amenorrhea, secondary amenorrhea, and functional amenorrhea. Primary amenorrhea is basically referred to a young girl that has not experienced menarche, at all. Secondary amenorrhea reflects a woman that has ordinary menstruation cycles, experiencing at least 3 months of menstruation cycle absence. Functional amenorrhea is a subtype of the amenorrhea caused by exaggerated different lifestyles.
- Each of the subtypes of amenorrhea has their own classification, as following:
| Amenorrhea classification | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Life style etiology | Lack of menarche | Lack of mensturation more than 3 months | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Functional amenorrhea | Primary amenorrhea | Secondary amenorrhea | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Stress related | Weight loss related | Exercise related | Hypergonadotropic hypogonadism | Hypogonadotropic hypogonadism | Eugonadotropic | Polycystic ovary syndrome | Hypothalamic-pituitary dysfunction | Hypothalamic-pituitary failure | Ovarian failure | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Amenorrhea is broadly classified as primary and secondary.
- Primary amenorrhea there is absence of menarche by the age of 16. Menstruation cycles never begin. There will be a delay of menses one year beyond the family history of first menses.
- Secondary amenorrhea is defined as absence of menses in a woman who had previously menstruated for at least 3 cycles or 6 months. Secondary amenorrhea is more common than primary amenorrhea.
The other type of classification based on the levels of gonadotropic hormones includes:
- Hypogonadotropic amenorrhoea refers to conditions where there are very low levels of serum FSH and LH.
- Normogonadotropic amenorrhoea - FSH levels are in the normal range.
