Correlation between age and curative effects of selective dorsal neurectomy for primary premature ejaculation

The use of selective dorsal neurectomy (SDN) as a surgical treatment of premature ejaculation (PE) has increased for many years in Asian countries.

To investigate the correlation between age and curative effects of SDN in primary premature ejaculation (PPE) in mainland China.

From September 2016 to September 2020, 65 patients with PPE treated with SDN were selected for study. All of the patients were followed up from 12 to 56 (30.07 ±13.48) months. They were divided into 3 groups according to age: group A (22-30 years, n = 23), group B (31-37 years, n = 20) and group C (38-45 years, n = 22). The 5-item version of the International Index of Erectile Function (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) results, erectile rigidity grade, intravaginal ejaculation latency time (IELT), ejaculation control abilities (ECA) scores, and sexual intercourse satisfaction (SIS) scores were assessed in the 3 groups before and after operation to evaluate the clinical efficacy of surgery.

Fifty-nine patients were finally followed up. The IIEF-5 scores and erectile rigidity grade of group A was significantly higher than that of groups B and C, both before and after surgery. The change of PEDT scores in group A was significantly higher than in groups B and C; the difference was statistically significant (p < 0.05). The IELT, ECA and SIS scores in group A were significantly higher than in groups B and C (p < 0.05). Operational efficiency ratio in groups B and C (65%, 70%) was significantly lower than in group A (95.24%).

The SDN as a treatment of PPE in different age groups allowed to achieve certain results. The highest surgical efficiency (95.24%) was observed in the 22-30 years age group and the lowest (65%) in the 38-45 years age group. Therefore, we believe that the best time for surgery is between 22 and 30 years of age.
