AMENORRHOEA
Menstruation
Is the endpoint of a cascade of events
which begins in the hypothalamus and
ends at the uterus
DEFINITION
Complete absence of menstrual
bleeding.
CLASSIFICATION
A.
Cryptomenorrhoea (False)
B. True Amenorrhoea
• Physiological
•
Pathological
Primary
Secondary
Primary:
No spontaneous onset of
menstruation by the age of
16 years.
Secondary:
Absence of menstruation
for 6 months or longer if
the patient has previously
experienced regular menses.
CRYPTOMENORRHOEA
Regular shedding of endometrium,but there is
mechanical obstruction.
CAUSES
Vagina
1 Imperforate Hymen
2 Non canalisation or absence of vagina
Cervix
1. Congenital
2. Acquired

Infection
Trauma
Surgery
CRYPTOMENORRHOEA
Signs
1. Amenorrhea
2. Pain
3. Retention of urine
Signs
1. Secondary sexual characters are present
2. Dark bluish membrane (imperforate hymen)
3. Pelvic mass
Treatment
1.Hymenectomy
2.Vaginoplasty
3.Cervical dilatation.
Physiological Amenorrhea
Prepuberty:
– Due to low production of gonadotrophic hormones
Pregnancy:
– Increased amounts of oestrogens & progesterone by
placenta
Lactation:
Increased levels of prolactin
Menopause:
ovaries unresponsive to stimulus of gonadotrophins
Constitutional delay:
Familial
PATHOLOGICAL
Causes:
Uterus
Ovary
Anterior pituitary
Hypothalamus
Others
Causes of Amenorrhea
