The absence of menstrual periods (amenorrhea) is a common type of menstrual problem in women of reproductive age. This condition involves an absence of menstruation for 3 months or longer in a sexually mature woman who is not pregnant or breastfeeding.
Amenorrhea is a symptom of other disorders, which can range from minor to serious. It is a symptom with many potential causes.
Primary amenorrhoea (menstrual cycles never starting) may be caused by developmental problems, such as the congenital absence of the uterus or failure of the ovary to receive or maintain egg cells.
Also, delay in pubertal development will lead to primary amenorrhea. It is defined as an absence of secondary sexual characteristics by age 14 with no menarche or normal secondary sexual characteristics but no menarche by 16 years of age.
Secondary amenorrhoea (menstrual cycles ceasing) is often caused by hormonal disturbances from the hypothalamus and the pituitary gland, from premature menopause or intrauterine scar formation (intrauterine adhesion/asherman’s syndrome.
