What is the Luteinizing Hormone (LH)? Function, Normal Levels, & How to Increase It

Luteinizing Hormone (LH) is a crucial reproductive hormone that plays a significant role in both male and female fertility. It regulates ovulation in women and testosterone production in men. Any imbalance in LH levels can lead to fertility issues, making it essential to understand its function, normal range, and ways to increase it naturally and medically.

At New World Fertility, we provide expert guidance on managing luteinizing hormone in males and luteinizing hormone in females to optimize fertility and improve reproductive health.

Luteinizing Hormone Function

In Females:

  • LH works with follicle-stimulating hormone (FSH) to regulate the menstrual cycle.

  • A surge in LH triggers ovulation, releasing a mature egg from the ovary.

  • It helps maintain the corpus luteum, which supports early pregnancy.

In Males:

  • Stimulates the production of testosterone in the testes.

  • Supports sperm production and overall reproductive health.

  • Works alongside FSH to ensure proper male fertility.


Luteinizing Hormone Normal Range & LH Levels Chart

Understanding normal LH levels in females and males is crucial for diagnosing fertility issues.

Normal LH Levels in Females (mIU/mL):

  • Follicular phase: 1.9 - 12.5

  • Ovulatory phase: 8.7 - 76.3

  • Luteal phase: 0.5 - 16.9

  • Postmenopausal: 15.9 - 54.0

Normal LH Levels in Males (mIU/mL):

  • Adult males: 1.24 - 7.8

A doctor at New World Fertility can evaluate LH levels and recommend treatments if there’s an imbalance.


Causes & Symptoms of Abnormal LH Levels

High LH Levels:

  • In Females: May indicate Polycystic Ovary Syndrome (PCOS) or menopause.

  • In Males: Could signal testicular failure or low testosterone.

Low LH Levels:

  • In Females: Could result from pituitary gland disorders or excessive stress.

  • In Males: May cause reduced testosterone production, affecting sperm quality.

Symptoms of abnormal LH levels include irregular periods, infertility, fatigue, and decreased libido.


How to Increase Luteinizing Hormone

If LH levels are low, there are several ways to boost them naturally and medically.

Natural Ways:

  • Healthy Diet: Consume foods rich in zinc, vitamin D, and omega-3 fatty acids.

  • Exercise & Stress Management: Regular physical activity and reduced stress improve hormonal balance.

  • Adequate Sleep: Poor sleep disrupts hormone production.

Medical Treatments:

  • Hormone Therapy: Injections like hCG can mimic LH effects.

  • Fertility Medications: Clomid or Letrozole help stimulate LH production.

  • Consult a Specialist: New World Fertility offers personalized treatments to regulate LH levels.
