The drug addiction in the buprenorphin with high dosage (BHD) by injectable way, represents a real plague in Tunisia, consequently, we are confronted with diverse complications including the sexual dysfunctions.

Identify and determine prevalence of the sexual dysfunctions among this population.

It is a transverse, descriptive study. We looked for sexual dysfunctions by using the international index of the erectile function (IIEF 15), among a population of 52 male users of BHD by injectable way.

The average score in the IIEF-15 was 36.65 with a standard deviation of 20.87, a negative correlation with duration and the quantity of consumption was noted.

The average erectile function (EF) was 15.63±9.26, which corresponds to a mild to moderate erectile dysfunction, whereas 31% had a severe dysfunction.

The average score of the orgasmic function (OF) was 6.35±3.52.

The average score of the sexual desire (SD) was 4.27±2.90.

The average score of the satisfaction with sexual intercourses (IS) was 5.77±4.54, an alteration was noted in 96% of the cases, which was correlated with the severity of the consumption.

The average score of the global satisfaction (OS) was altered at 92% of the subjects.

The majority of the subjects brought back the chronology of their disorders in after the consumption of BHD. No patient consulted in sexology.

It is thus important to educate stakeholders, on the frequency of sexual dysfunctions and the importance of their screening to improve the management of this problem.
