Sperm quality

Testosterone is a male sex hormone responsible for optimal sperm production and plays a central role in overall health and vitality in men.

Low testosterone is associated with decreased fertility, low libido, erectile dysfunction, depression, low energy, inflammation, weight gain, and poor general health. Low levels of testosterone also increase chances of cardiovascular and metabolic diseases, as well as some cancers.

Testosterone is measured by calculating total testosterone, then subtracting the amount which is bound (unusable) by SBGH (sex hormone binding globulin) to arrive at how much free (usable) testosterone is present.
