Description

Tradewell et al reported an equation based on serum follicle stimulating hormone (FSH) for predicting azoospermia in an infertile male. This can help to guide patient management.

Patient selection: male with infertility

 

Parameters:

(1) serum FSH in IU/L (normal 1.5 to 7.6 IU/L)

 

probability of azoospermia =

= (0.133 * ((FSH)^2)) - (0.965 * (FSH)) + 10.1

 

Performance:

• The area under the ROC curve was 0.71 to 0.78 depending on the population.

• R-squared is 0.95.
