What is the Origin of T/LH Ratio?

The term is a clinical calculation, combining the key hormonal components of the HPG axis: T for Testosterone and LH for Luteinizing Hormone. Its use is a standard part of the diagnostic workup for low testosterone and other gonadal disorders.

What is the Mechanism of T/LH Ratio?

In primary hypogonadism, the testes or ovaries fail to produce sufficient testosterone, causing the pituitary to compensate by increasing LH secretion via negative feedback, resulting in a low T and high LH, or a low T/LH ratio. Conversely, in secondary hypogonadism, the pituitary or hypothalamus fails to produce enough LH, leading to low testosterone and inappropriately low or normal LH, which may result in a normal or high T/LH ratio despite low T. This differential analysis guides the appropriate therapeutic intervention.

T/LH Ratio

Meaning

The T/LH Ratio is a diagnostic index representing the calculated ratio of total serum testosterone (T) concentration to serum Luteinizing Hormone (LH) concentration. This ratio is a valuable tool in clinical endocrinology, particularly for differentiating between primary and secondary hypogonadism. It provides insight into the functional integrity of the hypothalamic-pituitary-gonadal (HPG) axis and helps pinpoint the anatomical origin of hormonal dysfunction.
