LH is produced by the pituitary gland and triggers ovulation in women and testosterone production in men.
Diagnostic Value: LH testing aids in identifying ovulation disorders, menopause, PCOS, and pituitary abnormalities.
Clinical Importance: Abnormal LH levels can explain infertility, low libido, and hormonal imbalance. It is also used to time ovulation for fertility treatments.
Symptom Correlation: High LH levels may suggest ovarian failure or PCOS; low levels can indicate hypothalamic dysfunction or pituitary deficiency.
Because LH acts as a key reproductive signal, measuring it helps clarify fertility status and gonadal function.
