Enter the total testosterone (ng/dL) and the total Shbg (nmol/L) into the Calculator. The calculator will evaluate the Testosterone Shbg Ratio. 

Testosterone Shbg Ratio Formula

TSHBGR = T / SHBG

Variables:

  • TSHBGR is the Testosterone Shbg Ratio (ng/dL/(nmol/L))
  • T is the total testosterone (ng/dL)
  • SHBG is the total Shbg (nmol/L)

To calculate Testosterone Shbg Ratio, divide the testosterone in ng/dL by the total Shbg in nmol/L.

How to Calculate Testosterone Shbg Ratio?

The following steps outline how to calculate the Testosterone Shbg Ratio.


  1. First, determine the total testosterone (ng/dL). 
  2. Next, determine the total Shbg (nmol/L). 
  3. Next, gather the formula from above = TSHBGR = T / SHBG.
  4. Finally, calculate the Testosterone Shbg Ratio.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total testosterone (ng/dL) = 1.5

total Shbg (nmol/L) = 6.7

FAQ

What is the significance of calculating the Testosterone SHBG Ratio?

The Testosterone SHBG (Sex Hormone Binding Globulin) Ratio is crucial in assessing the amount of testosterone that is available for use by the body. It helps in diagnosing various hormonal disorders and conditions related to testosterone levels.

Can the Testosterone SHBG Ratio affect fertility?

Yes, an abnormal Testosterone SHBG Ratio can impact fertility in both men and women. In men, it can affect sperm production and libido, while in women, it can influence ovulation and menstrual cycles.

How often should the Testosterone SHBG Ratio be tested?

The frequency of testing depends on the individual’s health condition and the advice of their healthcare provider. It’s commonly tested when symptoms of hormonal imbalance are present or during routine health assessments.

Are there any factors that can influence the Testosterone SHBG Ratio?

Yes, several factors can influence this ratio, including age, weight, medications, liver function, and certain medical conditions. It’s important to discuss these factors with a healthcare provider when interpreting the results.
