Estrodiol is a naturally occuring female sex hormone that is arguably the most important hormone produced by the female body, the reduction of which signals the end of the childbearing phase of ha woman's life.

Estradiol is a female hormone essential for female sexual development.

Estradiol is a naturally occurring sex hormone, 90% of which is produced by the ovaries, the placenta in pregnant women and to a lesser degree by the adrenal cortex. It is regarded as the most important of all the estrogens produced by the female body. Although it is also present in men to a lesser extent where it is produced by the testes as an active metabolic product of testosterone.

Estradiol is responsible for the development of the female sex organs such as the uterus, fallopian tubes, Vagina, breast development, growth of the outer genitals and the distribution of female body fat and physical height.

The menopause for most women begins around 45 years old, although it could begin earlier and usually ends around the 55th year, however it could be slightly later. The menopause signals the end of the menstrual cycle and the child-bearing phase of a woman’s life and brings with changes in the female reproductive and hormonal systems.

As the egg supply diminish the body ovulates less frequently, causing changes in the menstrual cycle, which gradually stops over time, with a simultaneously tailing off of the oestrogens and progesterone levels in the blood.

The most common menopausal symptoms includes hot flashes, mood swings, weight gain, virginal dryness, loss of libido (sex drive), aching joints, irregular heart beat, night sweats, insomnia, forgetfulness, anxiety, depression, pain during sexual intercourse and fatigue . Symptoms vary for person-to-person depending on the level of oestrogen in the blood at any one time; therefore treatment ideally has to be tailored to meet the needs of each individual.

One of the tests undertaken by the health provider to confirm the onset of the menopause is to check the levels of Estradiol in the blood. The normal pre-menstrual level is 25-600pg/ml (picograms per ml), whilst post-menstrual women normally fall between 32pg/ml or less.

Scientific studies have indicated that hormone replacement therapy in the form of estradiol tablets or medicated patches are effective in controlling menopausal symptoms. Patch wearers are advised to change them every three to four days; however it is worth noting that with some individuals patches can cause skin irritation making oral medication the preferred option.

Estradiol helps to increase the oestrogen levels in the blood, essential for numerous bodily processes. It has a significant part to play in the improvement of the reproductive system, sexual functioning and bone strength by maintain bone mass and reducing the risk of osteoporosis.

There are significant side-effects associated with Estradiol therapy and guidelines suggest that it should only be used for the shortest possible period, because it can increase the possibility of heart attacks, deep vein thrombosis, blood clots, with smokers being at even greater risk.
