闭经

Amenorrhoea

Amenorrhoea is often subdivided into primary and secondary amenorrhoea. Primary amenorrhoea is defined as a failure to menstruate by the age of 16 years, while secondary amenorrhoea is the absence of menstruation for 6 months or more. This distinction is of little practical significance since many of the causes overlap.
