Progesterone is an important female hormone that plays a vital role in conception and a healthy pregnancy. The term 'progesterone' is derived from the Latin word 'gestare' which means 'to bear' or 'carry'.



Progesterone is secreted by the corpus luteum. The primary role of this hormone is to prepare the endometrium in the uterus for implantation of the fertilized egg. On implantation, the developing placenta discharges signals for production of progesterone. Progesterone is vital for the growth of the fetus. Little doubt that progesterone is known as the female sex hormone or reproduction hormone. Progesterone symptoms vary in non-pregnant and pregnant women, during ovulation or pregnancy and when the progesterone levels are either deficient or in excess.



Progesterone symptoms related to pregnancy: Progesterone levels peak during ovulation and lasts through the luteal phase. This triggers formation of the endometrium in providing the appropriate environment for the fertilized egg. The primary symptom in this phase is a slight rise in body temperature, which is measured by the BBT/fertility charting. In case fertilization and implantation occurs, further production of progesterone production is responsible for furthering of the pregnancy. In the event that fertilization does not occur, the progesterone level falls drastically; the reason for menses in women.

Progesterone and miscarriage: Low levels or a drop in progesterone levels during the first few weeks of pregnancy may result in miscarriage as progesterone stimulates uterine changes that support continuation of the pregnancy. There is significant increase in blood supply and endometrial tissue development.

Low Progesterone Symptoms-during menopause, commonly experienced symptoms due to low progesterone are hot flashes that also indicate low estrogen levels. The hot flashes in most cases cause serious health concerns. During a hot flash, there is a sudden surge of increased temperature in the upper parts of the body and very often, the person experiences reddening of the face. Sweating is not common and often hot flashes are accompanied by cold chills. Low progesterone symptoms are insomnia, dizziness, irritability, difficulty in concentrating and extreme mood changes.

Severe deficiency is known to cause a profound effect on emotions, many times leading to depression. Low progesterone levels are common at the start of menopause, a stage known as perimenopause, when women experience symptoms such as bloating and weight gain. Muscle and joint pain, and urinary incontinence are also common complaints.
