Testosterone is both a male and female sex hormone, but in males it is the most dominant sex hormone in the body. Responsible for sexual development and if too low can cause a variety of health issues and symptoms. Diagnosis of Low testosterone (or low-T) is said to be less than 300 nanograms per deciliter (ng/dL). Although optimal levels, or symptom-free and feeling good, should be between 600-1400ng/dL.
Testosterone for men plays a key role in male reproductive function, regulates sperm production, bone mass, libido, fat metabolism, muscle mass and strength. Low T can cause issues like erectile dysfunction (ED), fewer morning and softer erections.
The pituitary gland is responsible for regulating testicular function. The pituitary tells the body to make more Follicle Stimulating Hormone (FSH). FSH communicates to the Sertoli cells which tell the testicles to produce more sperm. The pituitary also regulates LH (Luteinizing Hormone). LH communicates to the Leydig cells which tell the testicles to produce more testosterone.
Testosterone is highest during puberty and starts declining in your 30s. Unfortunately, we have seen a more unnatural decline in testosterone since the 1960s, in fact an additional 1% annually.
Women also need testosterone for optimal health and body function!
If you have signs or symptoms of low testosterone, we recommend your testosterone levels be checked. This can be done with a simple blood test.
