Most menopausal women do not need to have their testosterone levels checked. Scientists from Monash University told this Speech.
Recently, a myth has circulated that low testosterone levels in women can lead to low mood, brain fog, fatigue and worsening menopausal symptoms. “Treat” this condition is offered with hormone replacement therapy.
As scientists explain, there is no “normal” level of testosterone in the blood, so it is impossible to diagnose testosterone deficiency in a woman. In addition, the same content of the hormone may cause adverse effects in one woman (acne, baldness or excessive hair growth on the face and body) while not affecting the body of another.
A blood test for testosterone levels at the start of a cycle may only be necessary for women with excessive facial and body hair growth or severe acne.
However, there is strong evidence that testosterone therapy can improve sex drive in postmenopausal women. Therefore, an increase in its level after consulting a doctor is indicated only for women with reduced libido.
But there is not enough evidence that testosterone is helpful for other symptoms or diseases. The general evidence available did not show any effect of testosterone on mood or cognition. Therefore, testosterone therapy should not be used to treat symptoms such as fatigue, low mood, muscle weakness and poor memory, or to prevent bone loss, dementia, or breast cancer.
But scientists continue to explore the potential effect of testosterone therapy on bone density and muscle mass loss after menopause.
According to another myth, it is not the concentration of testosterone in the blood that can affect a woman’s condition, but its relationship with the level of estrogen. If testosterone levels are lower than estrogen levels, so-called fatigue and other symptoms can occur. But a study by scientists showed that estrogen levels stay above testosterone at all stages of the menstrual cycle. However, with age, the level of testosterone decreases, but after 40 years its content in the blood almost does not change. Studies have not shown significant changes in testosterone levels during the transition to menopause.
