Enter the follicle stimulation hormone and the luteinizing hormone into the Calculator. The calculator will evaluate the Fsh Lh Ratio. 

Fsh Lh Ratio Formula

FLR = Fsh/Lh


  • FLR is the Fsh Lh Ratio ()
  • Fsh is the follicle stimulating hormone
  • Lh is the luteinizing hormone

To calculate Fsh Lh Ratio, divide the follicle stimulating hormone by the luteinizing hormone.

How to Calculate Fsh Lh Ratio?

The following steps outline how to calculate the Fsh Lh Ratio.

  1. First, determine the follicle stimulation hormone. 
  2. Next, determine the luteinizing hormone. 
  3. Next, gather the formula from above = FLR = Fsh/Lh.
  4. Finally, calculate the Fsh Lh 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.

follicle stimulating hormone = 80

luteinizing hormone = 90
