The FSH & LH panel measures both follicle stimulating hormone and luteinizing hormone together, providing comprehensive insight into reproductive function, fertility status, and hormonal balance.
This combined panel measures both FSH (Follicle Stimulating Hormone) and LH (Luteinizing Hormone), the two primary gonadotropins produced by the pituitary gland that regulate reproductive function. Testing both together provides more clinical value than either alone.
FSH and LH work in concert to regulate the menstrual cycle and fertility. FSH stimulates follicle development early in the cycle, while LH triggers ovulation mid-cycle. The ratio between these hormones is particularly important for diagnosing conditions like PCOS.
In men, both hormones are essential for sperm production and testosterone synthesis. Evaluating both provides insight into whether fertility issues originate from the pituitary gland or the gonads.

What's Measured
What This Test Measures
This panel measures both FSH and LH in mIU/mL. Normal early follicular FSH is 3-10 mIU/mL, LH is 2-15 mIU/mL. The FSH:LH ratio is normally close to 1:1 in early follicular phase. In PCOS, LH is often elevated relative to FSH (ratio >2:1).
Here is a guide to better understand your FSH lab results:
Who Should Consider This Test
Women investigating fertility issues, those with irregular periods or PCOS symptoms, women assessing menopause status, men with fertility concerns, anyone needing comprehensive reproductive hormone assessment.

When to Get Tested
No fasting required. For fertility and PCOS assessment, test on days 2-4 of the menstrual cycle. This timing provides the most useful baseline levels and FSH:LH ratio for diagnosis.
Understanding Your Results
Normal early follicular: FSH 3-10, LH 2-15 mIU/mL (ratio ~1:1). In PCOS, LH is often elevated with ratio >2:1. Elevated FSH with normal LH suggests diminished ovarian reserve. Both elevated suggests menopause.
