EQUINOXE study: Impact of relational cohesion and sexuality on the quality of life of patients treated with gonadotropin-releasing hormone agonist for prostate cancer.

Men with the greatest improvement in quality of life after initiating hormone therapy were those with, at baseline, testosterone deficiency symptoms (identified by QLQ-PR25 treatment-related symptoms score) or no/low sexual activity. Cohesion within the couple was not confirmed as an influence on the evolution of quality of life.
