LH (Luteinizing hormone) Test

Luteinizing hormone (LH) is a hormone produced by the pituitary gland in both males and females. It plays a key role in reproductive health by stimulating the production of sex hormones—testosterone in males and estrogen in females.

Why is the LH Test Important?

1. Ovulation: In women, LH surge triggers ovulation, the release of an egg from the ovary.
2. Menstrual Cycle: LH levels fluctuate throughout the menstrual cycle, helping regulate the menstrual cycle and fertility.
3. Fertility: Used to assess fertility and diagnose disorders such as polycystic ovary syndrome (PCOS) or hypothalamic-pituitary-gonadal axis disorders.
4. Hormone Therapy: Monitors hormone replacement therapy in menopausal women or fertility treatments.

When Should You Get an LH Test?

• Fertility Assessment: Used to time intercourse for couples trying to conceive.
• Irregular Periods: If you have irregular menstrual cycles or difficulty getting pregnant.
• Puberty: Used to evaluate early or delayed puberty.
• Hormonal Disorders: If you have symptoms such as acne, excessive hair growth, or menstrual irregularities.
