Impact of Prostate Needle Biopsy on Erectile Function in Nigerian Men

Background: Prostate biopsy has been described as a procedure without many complications. However, possible effect on erectile function remains controversial. The impact of finger-guided prostate needle biopsies (FGPNB) on erectile dysfunction (ED) was prospectively studied.

Materials and Methods: Seventy-nine men who underwent FGPNB completed the International Index of Erectile Function (IIEF)-5 questionnaires on the day of the biopsy, 1 week, 4 and 12 weeks after. Concomitant ED-related systemic diseases and/or medications that could affect erectile function were excluded.

Results: Age range was 50 years to 98 years with mean age of 67.6 years ± 10.7 years. Highest prevalence of ED was among age group 70 years to 79 years. Severity of ED increased with the increase in post biopsy weeks. The mean IIEF difference was significant at week 1 among the age groups (p=0.029) and between age groups 50 years to 59 years and 70 years to 79 years (p=0.038). Moderate ED (27.9%) and severe ED (27.9%) was prevalent in week 1 and 12 respectively.

Conclusion: Although the prevalence of ED was highest among age group 70-79 years with a significant mean IIEF difference between age group 50 years to 59 years and 70 years to 79 years, ED appeared not to be biopsy related in Nigerian men. However, there was a trend in the increasing severity of ED with post biopsy period.
