Introduction: The use of long-term opioids to treat patients with Chronic Pain (DC) can cause
hypogonadism, with Sexual Dysfunction (SD) being among its side effects. It should be noted
that SD is an infradiagnosticated and therefore, under-treated event.
Objective: To analyze the presence of SD in men and women with chronic non-cancer pain
(CNCP) treated with opioids. As well as, evaluate in the case of men the effectiveness of a
program of diagnosis and early referral to the Andrology Unit.
Methods: A prospective observational study was performed on a sample of 750 consecutive
outpatients who were treated at the Pain Unit for CNCP who received opioids for at least 12
months. They evaluated pain, Morphine Equivalent Daily Dose (MEDD), and adverse events
(AE) of opioids through standardized questionnaires and medical records reviews. Routinely, in
the case of men, they were referred to the Andrology Unit for routine follow-up. In the case of
women, they were referred to Sexual and Reproductive Health Unit at Health Centers.
Main outcome measures: Sexual function was assessed by the Female Sexual Function Index
(FSFI) in females and the International Erectile Function Index of Erectile Function (IIEF-EF) in
men.
Results: 33% of the 750 patients with CNCP reported having SD, with a statistically significant
frequency in men vs. women (33% vs. 25%, p <0.05) vs. 70%, p = 0.03) and a more sexually
active life (69% vs. 34%, p <0.05). The men received a DDEM with the highest number of
women, 70 (43-170) mg/day vs. 60 (30-102) mg/day, p = 0.016) at the same mean pain
intensity. 42% of men, improved with andrological treatment, with a significant correlation
between improved erectile dysfunction (ED) and improved sexual quality of life (VAS-EQ-5D 56
± 26 points, p = 0.000 ) And anxiety (HADS-A 7 ± 4 points, p = 0.048). In women, the shunt was
not effective, and its underdiagnosis persisted.
Conclusions: SD is a frequent AE in patients with CNCP in long-term opioid treatment, being
higher in men who receive higher MEDD than in women. In them, SD was associated with
hypogonadism in 19% of cases and its early derivation to Andrology improved its erectile
function in 42% of the cases.
