LH vs FSH: Key Differences Explained
Compare LH and FSH to learn which marker is more relevant for health assessment.
Why Compare LH and FSH?
Comparing LH and FSH is crucial because they are often used to assess similar yet distinct health conditions. Understanding their differences helps in selecting the right test and interpreting the results accurately.
LH vs FSH: Which Biomarker Matters?
LH and FSH are essential biomarkers used to evaluate different health conditions. Knowing when and how to interpret these biomarkers can significantly impact clinical decision-making.
Quick Comparison Table:
Biomarker | Purpose | Ideal Range | When to Test | Key Differences |
|---|---|---|---|---|
Stimulates ovulation and testosterone production | 1-20 IU/L | Evaluate fertility and hormonal balance | Peaks during ovulation | |
Regulates reproductive processes | 1-10 IU/L | Assess ovarian or testicular function | High levels indicate reproductive issues |
Key Takeaways:
FSH matures follicles; LH triggers ovulation and maintains luteal function.
An abnormal LH/FSH ratio can suggest PCOS or gonadal dysfunction.
Measure both to assess ovulation and hormonal regulation.
