Question

question 4
which of the following is a symptom of low testosterone levels in men?

• increase in muscle mass
• increase in body hair
• breast enlargement
• increased interest in sex

Explanation:

Identify the physiological role of testosterone

Testosterone is the primary male sex hormone, responsible for regulating male physical characteristics, maintaining muscle mass, bone density, body hair distribution, and libido (sex drive).

Analyze the effects of low testosterone levels

When testosterone levels are abnormally low (hypogonadism), the body experiences a reduction in these androgenic effects. This leads to symptoms such as decreased muscle mass, loss of body hair, and a reduced interest in sex (low libido).

Evaluate the given multiple-choice options

• Increase in muscle mass: Incorrect. Low testosterone leads to a decrease, not an increase, in muscle mass.
• Increase in body hair: Incorrect. Low testosterone typically causes a reduction or loss of body and facial hair.
• Breast enlargement: Correct. A lower ratio of testosterone to estrogen in men can lead to the development of breast tissue, a condition known clinically as gynecomastia.
• Increased interest in sex: Incorrect. Low testosterone is strongly associated with a decreased libido (reduced interest in sex).

Answer:

• Increase in muscle mass
• Increase in body hair
• Breast enlargement (Correct answer)
• Increased interest in sex
