Luteinizing Hormone (LH)
Here’s what it reflects — and what to do about it.
Longetic pulls together every lab and record you’ve had, follows how Luteinizing Hormone (LH) changes over time, and explains what’s shifting — so you walk into your next appointment prepared, with reminders for retests along the way.
What is Luteinizing Hormone (LH)?
A pituitary hormone that triggers ovulation in women and helps the testicles make testosterone in men.
LH is made by the pituitary gland and works closely with FSH; in women a mid-cycle surge triggers release of an egg, and in men it signals the testicles to produce testosterone. It is interpreted by sex and, in menstruating women, by cycle timing, and is usually measured together with FSH. Higher LH can be associated with the ovaries or testicles not working normally (including menopause) or conditions such as PCOS; lower LH can be associated with a pituitary or hypothalamus problem. A result is only meaningful alongside symptoms and other hormone levels.
What to know about Luteinizing Hormone (LH)
Understanding Luteinizing Hormone (LH) means knowing what it reflects, what tends to move it, and the signs that suggest it’s worth a closer look — so you can bring the right questions to your next appointment.
