Your Ovarian Reserve When there are less follicles (and eggs) left, it takes more FSH to select a follicle. So, higher FSH levels can indicate there are less eggs left — information critical to making a plan

The Science
Reserve tests track follicle stimulating hormone, or FSH for short. FSH is the hormone responsible for selecting the follicle to ovulate in a given cycle.
When there are less follicles (and eggs) left, it takes more FSH to select a follicle. So, higher FSH levels can indicate there are less eggs left — information critical to making a plan!


  • Low FSH results indicate that there likely is no diminished ovarian reserve.
  • Mid-range FSH results indicate ovarian reserve may have started to diminish.
  • High-range FSH results indicate ovarian reserve is potentially diminished.
  • If results are mid or high range, you should discuss with your doctor to make a plan.

What is ovarian reserve?

People born with ovaries are born with all their eggs and do not produce more over their lifetime. Your ovarian reserve refers to how many eggs your ovaries have remaining. Understanding your ovarian reserve can help you have more informed conversations with your doctor and get further assessment, if necessary.

When should I use this test?

Reserve tracks FSH (follicle stimulating hormone) early in the cycle to understand ovarian reserve. You’ll test on cycle days 5, 7, and 9. If you’re not yet familiar with cycle days, no worries! Cycle day 5 is 5 days after the start of your period.

Test FSH levels using first morning urine for the most accurate results. First morning urine should be collected first thing when you wake up after at least a 6 hour hold. Using anything other than first morning urine can cause inaccurate results

What are ideal FSH levels when trying to conceive?

An ideal FSH level when trying to conceive is below 10 mIU/ml. However, one single FSH test is not diagnostic, so we always recommend testing for multiple days (specifically cycle days 5, 7, and 9) to get an average of your levels.
