LH (in men)
Advanced wellnessalso luteinizing hormone
What it isA pituitary hormone that signals the Leydig cells of the testes to manufacture testosterone.
DoesDrives testicular testosterone production.
GoodA mid-range LH with normal testosterone signals an intact pituitary-gonadal axis.
BadHigh LH with low testosterone signals primary testicular failure. Low LH with low testosterone signals secondary (pituitary or hypothalamic) failure. Exogenous testosterone suppresses LH and shrinks the testes.
