Introduction
Luteinizing Hormone (LH) Reference Ranges:
- Males: 1.2–7.8 IU/L
- Females:
- Follicular phase: 1.65–15 IU/L
- Luteal phase: 0.61–16.3 IU/L
- Ovulatory phase: 21.9–56.6 IU/L
- Menopausal phase: 14.2–52.3 IU/L
LH stimulates ovulation and corpus luteum formation, and can be used to predict ovulation.
For women, hormonal levels in the body also reflect endocrine function. Luteinizing hormone (LH) is a critical indicator for ensuring normal ovulation. Moreover, LH levels can be used to predict ovulation. Abnormally low or high LH levels may adversely affect health. So, what are the normal reference ranges for luteinizing hormone?
Normal Reference Ranges for Luteinizing Hormone (LH)
Normal LH levels: Men: 1.2–7.8 IU/L Women: Follicular phase: 1.65–15.0 IU/L Luteal phase: 0.61–16.3 IU/L Ovulatory phase: 21.9–56.6 IU/L Menopausal phase: 14.2–52.3 IU/L
LH promotes ovulation and the formation of the corpus luteum, stimulates progesterone secretion, and helps predict ovulation timing. Levels significantly above or below the normal range may impair health. LH works synergistically with follicle-stimulating hormone (FSH) to regulate ovulation and supports the synthesis and secretion of estrogen and progesterone. In males, LH stimulates testosterone production and secretion by the testes. When LH levels are abnormal—either elevated or suppressed—dietary adjustments may help restore balance. It is also advisable to ensure adequate vitamin C intake. Consume ample fruits and vegetables, maintain proper hydration, and engage regularly in physical activity and outdoor exercise.
Luteinizing hormone (LH) is a vital hormone whose cyclical fluctuations in women drive ovulation and regulate menstrual cycle progression. In daily life, it is essential to monitor whether LH levels remain within the normal physiological range. We hope this information has been helpful. Wishing you optimal health and happiness!
