Low Testosterone: Unveiling Causes, Symptoms And Treatments

Testosterone is a hormone known for its crucial role in the development and maintenance of male reproductive organs and characteristics. The female body also produces Testosterone, although very low compared to males. In females, Testosterone impacts their reproductive (including menstrual) health, physiological health, cosmetic health (appearance, voice density, etc), and overall physical health. 

What Is Low Testosterone?

Low Testosterone, aka Low T or male Hypogonadism or Testosterone Deficiency Syndrome, is a condition where the body doesn’t produce sufficient Testosterone. A human being who is male by birth has testicles (two) as a part of their reproductive organs. Low T or male Hypogonadism is when testicles aren’t able to produce enough Testosterone hormones.

The condition of low levels of Testosterone hormones is associated with males, whereas females tend to suffer from high Testosterone levels more commonly. 


The term Male/ Men here refers to Transgender Men and Cisgender Men as well.  

Testosterone levels vary from person to person, but it is common for males to experience low Testosterone as they age. Not all men suffer from Low Testosterone, and many of them can maintain normal levels throughout their lives.

Some younger males can also experience Low Testosterone levels, but there are therapies and medications to treat the same. 

  • Normal Testosterone Levels in Males: 00 to 1000 nanograms per deciliter (ng/dL) or 10 to 35 nanomoles per liter (nmol/L)
  • Low Testosterone Levels in Males: Less than 300 nanograms per deciliter (ng/dL)
  • Normal Testosterone Levels in Females: 15 to 70 nanograms per deciliter (ng/dL) or 0.5 to 2.4 nanomoles per liter (nmol/L)

Unlike males, females tend to experience High Testosterone conditions, which impact their reproductive and menstrual health.

Causes Of Low Testosterone Levels

Factors that result in low Testosterone levels in males include:

  • In males, Testosterone levels naturally decline after the age of 30.
  • In some men, testicles don’t produce enough testosterone, a condition referred to as Hypogonadism. It can be a result of a problem either with the testicles, pituitary, or hypothalamus.
  • Obesity and abdominal fat may result in low testosterone levels.
  • Type 2 Diabetes can lead to low Testosterone levels.
  • Chronic medical conditions, including HIV/ AIDS, liver or kidney disease, and similar, can impact the production of Testosterone hormones.
  • Testicle injury or even trauma can impact Testosterone production.
  • Radiation treatment or Chemotherapy can result in permanently low Testosterone levels.
  • Medications like Corticosteroids and opioids can impact the production of Testosterone hormones. 
  • Certain infections and Genetic conditions can also suppress Testosterone production.
