Age-associated testosterone decline in men: clinical issues for psychiatry

Area of Science:

• Endocrinology
• Geriatrics
• Psychiatry

Background:

• Aging men experience a natural decline in testosterone levels.
• This decline, sometimes termed andropause or low-testosterone syndrome, is associated with various physical and psychological symptoms.
• The clinical significance and diagnostic criteria remain subjects of ongoing research.

Purpose of the Study:

• To review current knowledge on diagnosing and treating testosterone decline in aging men.
• To explore the psychiatric implications of low testosterone.
• To assess the role of testosterone replacement therapy.

Main Methods:

• A comprehensive MEDLINE search was performed.
• Keywords included "male climacteric," "andropause," and "testosterone replacement therapy."
• Literature review included historical publications via reference lists.

Main Results:

• Symptoms of testosterone deficiency can include depression, anxiety, irritability, insomnia, weakness, diminished libido, and cognitive changes.
• While testosterone levels decrease with age, there's significant individual variation, and the link to psychiatric symptoms is complex, potentially involving other hormonal factors.
• Testosterone replacement therapy might benefit hypogonadal men, but robust long-term efficacy and safety data are limited.
• A thorough biopsychosocial evaluation is recommended for men with low-testosterone syndrome.

Conclusions:

• Testosterone decline in men is not a direct parallel to female menopause.
• Symptoms associated with low testosterone may overlap with primary or secondary psychiatric disorders.
