Introduction
Luteinizing hormone is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH ("LH surge") triggers ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell-stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with follicle-stimulating hormone (FSH).
Advantages
✔ Low sample requirements: direct testing of trace serum without dilution
✔ The ratio of FSH to LH can be used as one of the evaluation indicators of ovarian function
Clinical Significance
✔ Differential diagnosis of hypothalamus, pituitary or gonadal dysfunction
✔ Determine menopause, ovulation time and monitor endocrine therapy
✔ One of the important indicators of sexual function attenuation
