Testosterone deficiency, also known as hypogonadism or low T, is a condition where the body does not produce enough testosterone. Testosterone is the primary male sex hormone and plays key roles in the development of male reproductive tissues as well as promoting secondary sexual characteristics such as increased muscle mass and bone density, growth of body hair, and a deepened voice.
Symptoms of low testosterone can vary but may include:
- Decreased sex drive and erectile dysfunction
- Fatigue and low energy levels
- Loss of muscle mass
- Increased body fat
- Difficulties with concentration and memory
- Irritability and depression
Causes of testosterone deficiency include primary and secondary hypogonadism.
Primary hypogonadism arises from dysfunction in the testicles themselves. This can be caused by injury, infection, chemotherapy or radiation treatment, undescended testicles at birth, or inherited conditions.
Secondary hypogonadism indicates a problem with the pituitary gland or hypothalamus in properly signaling the testicles to produce testosterone.
Diagnosis involves having your testosterone levels checked through a simple blood test. Symptoms combined with
total testosterone levels below 300 ng/dL generally indicate hypogonadism. Your doctor may check additional related hormones such as luteinizing hormone (LH), follicle stimulating hormone (FSH), prolactin, and estradiol as well.
Treatment options for low T include:
- Testosterone replacement therapy - Various forms exist including gels/creams, injections, patches and pellets surgically implanted under the skin. Each have their pros and cons.
- Medications - Certain medications aim to alter hormone levels in the body to try to boost endogenous testosterone production.
- Lifestyle changes - Improving diet, exercise, sleep and stress management can help mitigate hormone imbalance for some individuals.
If you suspect you may be experiencing low T based on your symptoms, I recommend having your testosterone levels evaluated by a knowledgeable hormone therapy clinic like
Hormone Health Center. Their dedicated clinicians provide free consultations to determine if hormone optimization programs could help resolve your deficiency symptoms and restore energy, strength and vitality.
I hope this overview gives you a good understanding of what defines testosterone deficiency, its associated symptoms and both medical and lifestyle management options available. Let me know if you have any other questions!
