Understanding Testosterone: How It Works in Men and Women

Testosterone is often labeled as the “male hormone,” but this powerful molecule plays essential roles in both men and women. At Vitality, we view hormones like testosterone not just as chemical messengers, but as critical influencers of vitality, mood, metabolism, and longevity.

What Is Testosterone?

Testosterone is a steroid hormone primarily produced in the testes in men and in smaller amounts by the ovaries and adrenal glands in women. It belongs to a class of hormones called androgens, which are responsible for the development of male characteristics, but that’s only part of the story.

How Testosterone Works in the Body

Testosterone affects nearly every system in the body:

In Men:

• Development & Sexual Health: Testosterone is responsible for the development of the penis, testes, deep voice, and facial/body hair during puberty. In adulthood, it maintains libido, sperm production, and erectile function.

• Muscle & Bone Health: It promotes muscle mass and bone density—two key factors in healthy aging and physical performance.

• Mood & Cognition: Testosterone impacts energy levels, motivation, and even mental clarity.

• Metabolism: It helps regulate fat distribution, insulin sensitivity, and blood sugar control.

In Women:

• Hormonal Balance: Though present in lower amounts than in men, testosterone helps balance estrogen and supports overall hormonal harmony.

• Libido & Sexual Function: Testosterone plays a role in sexual desire, arousal, and orgasm in women.

• Muscle & Bone Support: It contributes to lean muscle maintenance and bone strength, especially post-menopause.

• Mood & Energy: Like in men, low testosterone can contribute to fatigue, low mood, and reduced motivation.

Signs of Low Testosterone

In both sexes, testosterone levels naturally decline with age. However, imbalances, especially when paired with stress, poor nutrition, or chronic illness. It can trigger symptoms like:

• Fatigue

• Weight gain (especially abdominal)

• Low libido

• Mood swings or depression

• Brain fog

• Loss of muscle mass

• Decreased physical performance

At Vitality, we don’t just look at lab numbers. We assess how hormones interact with your environment, stress levels, sleep, nutrition, and lifestyle. We aim to address the root cause of hormonal imbalances, not just mask symptoms.

From there, we create an individualized plan that may include:

• Nutrition therapy

• Targeted supplements (like zinc, vitamin D, or ashwagandha)

• Sleep and stress optimization

• Resistance training

• Hormone replacement therapy, when appropriate

Testosterone isn’t just about sex drive or muscles. It’s a vital hormone for whole-body health in both men and women. At Vitality, we can support optimal hormone levels safely and holistically for a life of energy, strength, and clarity.
