What Every Guy Needs to Know About Testosterone

For years, the fitness industry has pushed one message: testosterone is king. From muscle-building to libido, stamina, and strength, testosterone has been framed as the key to male vitality. But here’s what they don’t tell you—testosterone doesn’t work alone. You can often achieve better results by understanding how all your hormones interact.

The production of testosterone and its levels depends on a delicate hormonal balance.

• Luteinizing hormone (LH) tells the testes to produce testosterone.
• Follicle-Stimulating Hormone (FSH) supports sperm production and prevents testicular shrinkage.
• Estradiol (E2) and progesterone (Pg) regulate testosterone conversion and overall balance, and high levels can inhibit testosterone production.
• Sex Hormone-Binding Globulin (SHBG) controls how much testosterone is available for use.

Before starting any performance-enhancement routine, check our Men’s Vitality Hormone Profiles. Monitoring these hormones helps you to prevent testicular atrophy, maximize muscle gains, avoid plateaus, and reduce side effects like fatigue and water retention. Train smarter and recover better with proper hormone balance. 

Three Years of Illness: Symptoms Subside Only to Return

Anderson was feeling really troubled—he kept getting sick.

Many think testosterone is the only male hormone. Nothing could be further from the truth.

When it comes to male hormones, testosterone often takes the spotlight as the ultimate symbol of masculinity, but it's just one piece of the puzzle. Understanding the power of all male hormones helps us embark on a journey of self-discovery and personal growth.

What Hormones Contribute to Your Masculine Features?

Many think testosterone is the only male hormone. Nothing could be further from the truth. 

Our culture is obsessed with this one androgen hormone, yet it is part of a group of hormones that give men their male characteristics. 

Dear Hormones,  
   Where have you gone, and just when I need you the most?

Behind every earnest ambition, desire, and pursuit, there is a hormone driving our passions. Hormones play as much of a role in a man’s interests as do his diet, sleep, and exercise. Our human drives are the result of hormones transforming energy into motivational pursuits.

With more recent science, we see that men have hormonal cycles just like women—with spikes and plunges even more drastic than those experienced during a menstrual cycle. For some men, these cycles can last for many years, caused by an underlying hormonal imbalance.

Is Your Man Going Through Menopause? Find out!

While you’ve got your hot flashes, your man is going through his own menopause, called andropause. Like women, men experience the so-called ‘change of life’ as a result of declining hormones, specifically low testosterone.

Andropause, however, is a more gradual process than the rollercoaster many women experience during menopause, with only a 1 percent annual decrease in testosterone, beginning at age 30.

Reduced hormone levels due to natural aging can affect men, too!

Testosterone, likely the first hormone that you think of in regard to men’s sexual health. 

Testosterone is essential for strength, stamina, the development of the reproductive system, strong bones, and a healthy libido. 

Does "Low Testosterone" Need to Be Treated?

Testosterone is often associated with strength and youth and has several important functions.

As men reach the fourth decade of their lives, growth hormone (made by the pituitary gland) begins to decline. 

Although some men choose to accept the inevitability of the drop, others naturally increase their levels of growth hormone by upping the intensity of resistance training.

Men: Keep that youthful, vital, and virile feeling through midlife.

Men are not immune to midlife changes. They too experience the so-called change of life as a result of declining hormones, specifically low testosterone, which is commonly seen beginning in the fourth decade of life. This is often associated with symptoms of aging in males referred to as "andropause," named after the androgens, the medical name for male hormones. This is the counterpart to menopause in women when ovarian production of estrogens and progesterone begins to decline. But for men, it is a more gradual process than the rollercoaster many women experience during menopause.
