If you thought Testosterone was only a male hormone, then think again! Although typically thought of as a male hormone, women also produce testosterone (T), but in much smaller quantities.

an androgen hormone, is produced in the ovaries of women, as opposed to the testes in men. The adrenal glands also kick in a small amount in both sexes.

The majority of testosterone produced in the ovaries is converted to estradiol, the biologically active form of estrogen, by a process known as aromatization. This process is named after the chief enzyme, aromatase, which facilitates the conversion to maintain homeostasis.

Symptoms of Low Testosterone in Women

Symptoms of low T in females can often be overlooked and unfortunately most doctors do not test women for this important hormone since it is not considered an immediate health risk.


Testosterone, in tandem with estrogen, vitamin D, vitamin K, minerals and other hormones helps to modulate bone loss. As a woman, it is especially important to reduce the risk of osteopenia or osteoporosis (1). Women with osteoporosis are more susceptible to bone breaks and fractures which can cause severe complications especially in older patients. Bone loss in the face also occurs with the aging process.
A [T] deficiency may accelerate this bone loss and result in premature aging of the facial structures as illustrated in the figure.


Most doctors look to the thyroid when weight gain is an issue for women. Although this must be addressed, it often overshadows other hormone imbalances, including low testosterone, high estrogen and insufficient progesterone. Muscle mass burns more calories fat and keeps the metabolism in check, so a decrease in lean muscle tissue can lead to weight gain if the diet and exercise are not changed accordingly.

Women with diminishing testosterone levels also experience changes in muscle tone and bone density, which can have a significant impact on the appearance and character of the body. These symptoms usually start to appear when women are in their mid-30s, but all too often, they’re chalked up to simply being a part of getting older when in fact, they are treatable and in many cases, reversible(3).

Body toxins such as plasticizers, heavy metals and environmental toxins should also be evaluated for their known endocrine disruption properties.


Unexplained mood swings, sustained low mood and even bouts of depression are linked to low levels of testosterone. This hormone helps with mental focus and mood stabilization, and motivation so it is of no surprise that these symptoms can be misdiagnosed and treated with antidepressant medication (4)


The body’s energy systems are rather complicated and a single “smoking-gun” is often not the case. If you struggle to get through your day, have a hard time getting out of bed or feel exhausted after activities that normally don’t cause fatigue, Testosterone deficiency may be to blame. Of course you should have a thorough examination and testing of the adrenals, thyroid and mitochondrial dysfunction also, but low testosterone often goes undetected in women.


Although low libido is most commonly associated with low testosterone in men,  woman experience more sudden and extreme sexual changes. These may include reduced libido, vaginal dryness, and a general disinterest in sexual relations. But there is a solution as Dr. Davis states:

“It is the clinical experience of the author that a subset of pre-menopausal women with sexual dysfunction and reduced circulating androgen [T] levels significantly benefits from judicious parenteral testosterone replacement.”

What are the side effects of excess testosterone?

If testosterone is included in your hormone replacement program, it is is important to start low and go slow. Fortunately, since the dosage in women is much less than men, when given proper dosages of testosterone, there are very rarely any negative side effects.

Excessive testosterone can cause acne, body hair growth and scalp hair loss in women. Excessive testosterone supplementation, such as with anabolic steroids used by athletes, also tends to drop high-density lipoprotein cholesterol levels (HDL), the “good” cholesterol. Lower HDL levels increase the risk of heart disease.

If you’re experiencing any of these symptoms, the next best step is to consult with your doctor or take advantage of a limited time FREE consultation at VIOR. We’ll discuss your symptoms, check your levels and determine if testosterone or bioidentical hormone replacement therapy is right for you.
