What is a good FSH level?

BioForge works to an optimal range rather than the lab's reference flag. For FSH that is 2–8, measured in mIU/mL. A result inside the lab's normal range can still sit outside the range where most people feel and function well.

FSH

Measured in mIU/mL

The pituitary's signal for sperm production. Reads directly on fertility potential.

What the numbers mean

These are the ranges BioForge works to. They are not the same as a lab's reference range, which is built from the general population rather than from people who feel well.

Low

<1.5

Optimal

2–8

High

>12.4

What moves FSH

Same drivers as LH. High FSH points to testicles that are struggling to produce sperm. This number is critical before starting therapy if children are still on the table.
