What is amenorrhea?
Amenorrhea is the medical term for absent menses (no period). Missing a single period is not considered as amenorrhea although this should not occur in a healthy female unless there are short term disturbances. Amenorrhea is a total lack of menstruation that occurs for 6 months or more. There are two types of amenorrhea – primary and secondary amenorrhea.
Types of Amenorrhea
Primary amenorrhea is the lack of menstruation in a girl who is 16 years or older or if there are signs of puberty present for more than 2 years with no menses. This means that menarche (the onset of menstruation) has not occurred as yet under the the abovementioned conditions.
Secondary amenorrhea is when menses is absent for 6 consecutive months or more in a girl or woman who was previously menstruating. Pregnancy and menopause are two common causes that are not pathological but there are other causes that may be a result of minor or serious medical conditions.

Ovulation is controlled by two female hormones, known as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) which may be monitored in cases of infertility or difficulty in conceiving. A regular menstrual cycle lasts between 28 to 32 days although a cycle as short as 26 days or as long as 35 days is considered within the norm. Ovulation usually occurs approximately 14 to 16 days before the next period but this may vary depending on the length of the individual menstrual cycle. The most fertile period is considered to last approximately 3 to 4 days within the cycle starting a day or two before ovulation. If the egg cell is not fertilized within this time period, it is ‘discarded’.
