Natural Hormone Levels In Women

Hormones are the most important substances that body produce because these are the substances that ultimately control all the body functions. Generally both the males and females have the same hormones. But from the onset of puberty, various hormones start to secrete in different amounts in the males and females. It is at this time that some hormones become especially active in women.

Generally hormones that are associated with womanhood are estradiol and estrogen, progesterone, Luteinizing hormone or LH and follicle stimulating hormone or FSH. Though Testorterone is considered a male hormone, it is also present in small amount in females. Other hormones that play their parts in a female human being are Prolactin and the Human Chorionic Gonadotrophin. The later plays a role in continuation of progesterone secretion during pregnancy.

It is important the body produces all these natural hormones in the right quantity. Increase or decrease in secretion can result in various complications. But what are the right levels of these hormones in women?

Estrogen And Estradiol

The most important hormone for any woman is estrogen because it plays the most important role in giving a woman her feminity. This hormone is actually the combination of 3 hormones of which the most important is the estradiol. The normal level of estradiol is between 25 and 75 picograms per milliliter during the second or third day of menstrual cycle. A higher reading at this time will indicate that the egg count inside the body is getting low or presence of a functional cyst.


The progesterone falls into the group of steroid hormones and it plays important role in fertility and pregnancy along with estrogen. The normal range of progesterone in human being is less than 1.5 nanogram per milliliter on day 3 and this rises as ovulation progresses. This is also called follicular phase level. During pregnancy the level can rise up to 300 ng/ml.

Luteinizing Hormone (LH)

This hormone falls in the class of gonadotropic hormone. It is responsible for stimulating the ovaries and it controls the ovulation of mature follicles. The normal level of this hormone is less than 7 mIU per milliliter on day 3 which can increase to more than 20 mIU/ml on surge day. This surge is the preovulatory LH surge which is the burst of LH that enables a mature egg to burst through the ovary wall.

Follicle Stimulating Homone (FSH)

Follicle stimulating hormone or FSH is responsible for the maturation of ovarian follicle. The normal level of this hormone in an adult female is between 3 and 20 mIU per milliliter. This hormone is often taken to be indicator of the ovarian reserve. The FSH is tested along with LH and the healthy ratio between the two is 1:1. The ratio is  used to determine Polycystic Ovary Syndrome or PCOS. When the LH is on the higher side, it indicates the possibility of the PCOS.


Testosterone is present in small amounts in women and the normal level of free testosterone is between 7 and 3.6 picogram/ml while the total testosterone count is between 6 and 86 ng/ml in women. It is responsible for libido, sexual stimulation, etc.
