What is the Origin of Sexual Vitality Index?

This index was created to bridge the gap between laboratory endocrinology and the patient-reported outcomes crucial for quality of life assessment in andrology. Index creation standardizes the integration of quantitative and qualitative data.

What is the Mechanism of Sexual Vitality Index?

The index mechanism relies on a weighted mathematical aggregation where changes in bioactive hormone levels directly influence the score, moderated by patient-reported frequency and intensity of sexual function markers. Restoration of this index implies optimizing the neuroendocrine signaling required for desire and the peripheral vascular and muscular function necessary for physical response.

Sexual Vitality Index

Meaning

The Sexual Vitality Index is a composite clinical score derived from correlating objective hormonal metrics, such as free testosterone and DHEA-S, with subjective patient reports regarding libido, erectile function, and overall sexual satisfaction. It functions as a holistic measure of androgenic impact on sexual health, acknowledging that biochemistry alone is insufficient for assessment.
