Indicator Explainer
Luteinizing Hormone
A heterodimeric glycoprotein hormone secreted by the gonadotropic cells of the anterior pituitary gland. This hormone is involved in stimulation of testosterone production by Leydig cells in males and triggering ovulation and corpus luteum development in females.
This page explains what the indicator is and how results are interpreted in general terms. Reference ranges depend on the laboratory, the method, and your own situation — no single “normal value” applies to everyone. This page is health information, not a diagnosis. For symptoms, treatment, or urgent concerns, contact a healthcare professional.
