High Testosterone in Women

The information provided herein does not constitute an expert or medical advice, nor intended to replace such advice.

Women Health

Most people think of testosterone as a male hormone. Although it’s certainly true that testosterone has important effects in a man’s body, testosterone is also important for women. If a woman’s testosterone levels are too high or too low, then she may experience a variety of health effects.

What happens when a woman has high testosterone? How does testosterone affect females’ bodies? Is there anything that can be done to reverse the effects?

What does testosterone do for women?

Testosterone is actually just one of a class of hormones known as androgens. Women produce testosterone in their ovaries, along with the other sex hormones, estrogens (which are also a group of hormones) and progesterone. Although a woman’s testosterone levels are far lower than those of men, this hormone is important for women’s health. Testosterone is important in regulating mood, maintaining sex drive, maintaining a healthy bone mass, and even making enough blood cells in the bone marrow.

Abnormal testosterone levels in females can cause a variety of effects. Low testosterone and high testosterone are both associated with health problems in women.

What are the symptoms of high & low testosterone in females?

In women, high levels of testosterone can lead to infertility. High androgens in females interfere with the maturation of eggs in the ovaries. They also block ovulation, which is the process of an egg being released from the ovary.

In addition, a woman with high testosterone may develop body characteristics that are typically associated with males. This process is known as virilization. Some of the effects include: 

  • Deepening of the voice.
  • Hirsutism, which is increased growth of body hair, particularly in areas typically associated with males (such as on the face, chest, and back). 
  • Male-pattern balding. 
  • Acne and excessively oily skin.
  • Increased muscle mass.
  • Decreased breast size.
  • Enlargement of the clitoris.

How do I know if I have high testosterone?

If a woman has signs that indicate a high testosterone level, then the next step is to test her testosterone levels. This is done by a blood test. The sample is usually collected early in the morning. Because the level of testosterone in the blood varies throughout the day, standardizing the time of day that the test is done allows for more accurate results. A regular STD blood test will not check hormone levels. You need to order a specific hormone test to find out your testosterone level.

Because of differences in the protocols used by different laboratories for measuring testosterone, the normal levels vary between labs. When you get your lab test, the range of normal values found in that lab will be listed. In general, the approximate normal level of testosterone in a woman is between about 8 and 60 ng/dL. By contrast, in men, normal testosterone levels range from about 240 to 1000 ng/dL. However, you should check your level against the normal range produced by that laboratory’s specific protocols to find out whether your level is considered to be elevated.

What is the cause of high & low testosterone in females?

There are a variety of possible reasons for high testosterone in females. Some of these include:

  • Polycystic ovary syndrome (PCOS). In women with this condition, the ovaries produce many follicles, but they don’t ovulate regularly. The condition is associated with high levels of androgens, so women often show the side effects of high testosterone in females. They also commonly experience infertility. In addition, PCOS is associated with insulin resistance, abnormalities in the levels of fats (such as cholesterol) in the blood, and other effects. The exact cause of the syndrome is not known, but PCOS is common, occurring in about 6 to 10% of all women in the US.
  • Congenital adrenal hyperplasia (CAH). This is a congenital condition in which the adrenal glands produce too much cortisol, which is a stress hormone. Because women produce testosterone in the adrenal glands as well as in the ovaries, increased testosterone levels can also occur as a result of this condition.
  • Certain rare types of tumors. If a type of cell that produces testosterone becomes cancerous and starts to grow out of control, and the tumor cells continue to produce testosterone, then the levels of testosterone may rise excessively. These types of tumors are not common, but they can occur.
  • Taking anabolic steroids. In women who are bodybuilders or who are active in athletic competitions, some may choose to take steroids, which are a synthetic form of testosterone. This can lead to the effects of high testosterone on the female body. In some cases, women are exposed to testosterone accidentally – if a partner is taking testosterone as a skin cream, then she can be exposed through skin to skin contact.

There are also other possible causes of excess testosterone in women. In some cases, the cause is never determined. Genetics are believed to play a role, but researchers are still working to discover all the possible causes of high testosterone in women.

Are there drugs that lower testosterone levels in females?

For women who are suffering from the effects of high testosterone on the body, the first line of treatment is usually birth control pills. These contain estrogen and progesterone. Because the effects of sex hormones in the body are mediated by the relative ratios of the various hormones more so than by the absolute levels, bringing the levels of these “female” hormones up can help to counter the effects of testosterone. However, in women who are actively trying to conceive, this will not be the best solution and another option will be tried instead.

In general, doctors will recommend trying birth control pills for a minimum of six months. This is because the impacts of changes in sex hormone levels can take a while to become obvious, and so it’s important to give the therapy a chance to work. 

However, if a woman still shows signs of elevated testosterone, then there are medications known as anti-androgens. These medications block testosterone from attaching to its receptor, so that it doesn’t have the unwanted effects. Some of the options include spironolactone and metformin.

Can testosterone help women lose weight?

In general, men have a lower body fat percentage than women do. This has led to the idea that taking testosterone is a good way for a woman to reduce her body fat and lose weight. 

However, studies have shown that testosterone is not effective for weight loss. It also tends to cause a woman to experience the side effects of high testosterone in females. Most women who are trying to lose weight are interested in having a thinner, but still feminine, body shape. Taking testosterone will generally cause the body to look more masculine, in addition to being ineffective for weight loss.

Can too much testosterone in a woman cause weight gain?

Testosterone is associated with increases in muscle mass. If a woman has high testosterone, then she may gain weight because of this increase.

In addition, testosterone can lead to insulin resistance, which can in turn lead to weight gain. At the same time, the effect goes both ways – insulin resistance can also lead to higher testosterone. When women with PCOS lose weight, they often experience a decrease in their testosterone levels.
