The Luteinizing Hormone (LH) Test is a blood test that measures the level of Luteinizing Hormone (LH) in the bloodstream. LH is an important reproductive hormone produced by the pituitary gland that regulates ovulation, menstrual cycles, testosterone production, and reproductive function in both women and men.
This test helps evaluate hormonal balance, fertility problems, menstrual irregularities, ovarian function, testicular function, and disorders affecting the pituitary gland or reproductive system.
1.Luteinizing Hormone (LH)
Measures LH, a pituitary hormone that triggers ovulation in women and stimulates testosterone production in men.
Also known as: LH Blood Test, Luteinizing Hormone Blood Test, LH Hormone Level Test, Interstitial Cell Stimulating Hormone Test
The Luteinizing Hormone (LH) Test measures the amount of LH present in the blood. LH is produced by the anterior pituitary gland and works together with other reproductive hormones to control sexual development and fertility.
In women, LH plays a key role in triggering ovulation and supporting the menstrual cycle. In men, LH stimulates the testes to produce testosterone, which is essential for sperm production and male reproductive health.
Abnormal LH levels may indicate problems involving the pituitary gland, ovaries, testes, or overall hormonal regulation.
The LH Test measures the concentration of Luteinizing Hormone in the blood. LH is a reproductive hormone that regulates important functions related to fertility and sexual health.

The test requires a blood sample collected from a vein.
Before the test:
| Parameter | Normal range |
|---|---|
| Luteinizing Hormone (LH) - Male | Approximately 1.7–8.6 mIU/mL |
| Luteinizing Hormone (LH) - Female (Follicular Phase) | Approximately 2.4–12.6 mIU/mL |
| Luteinizing Hormone (LH) - Female (Mid-Cycle Peak) | Approximately 14–95.6 mIU/mL |
| Luteinizing Hormone (LH) - Female (Luteal Phase) | Approximately 1.0–11.4 mIU/mL |
| Postmenopausal Women | Approximately 7.7–58.5 mIU/mL |
| Note | LH reference ranges vary significantly depending on age, sex, menstrual cycle phase, pregnancy status, and laboratory methods. Results should always be interpreted by a qualified healthcare professional along with symptoms and other hormone test results. |
Reference ranges can differ between labs. Your report shows the range used by the lab.
The LH Test is a blood test that measures Luteinizing Hormone levels to evaluate reproductive health, fertility, and hormonal balance.
LH plays an important role in ovulation in women and testosterone production in men.
No. Fasting is generally not required unless advised by your healthcare provider.
High LH levels may occur due to menopause, reduced ovarian or testicular function, or certain hormonal disorders.

Low LH levels may be associated with pituitary problems, hormonal imbalance, or reduced stimulation of reproductive organs.
Yes. In women, LH levels naturally change during different phases of the menstrual cycle and increase significantly around ovulation.
Yes. LH testing is commonly used along with other hormone tests to evaluate fertility and reproductive function.
Yes. In men, LH stimulates the testes to produce testosterone, so abnormal LH levels may affect testosterone production.
The frequency depends on the reason for testing, symptoms, treatment plan, and your healthcare provider's recommendation.
