EjD reduces sexual activity and male fertility. Imipramine (IMI) has been empirically used for EjD. However, research using animal models and clinical studies on EjD is limited.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Aim<\/jats:title>\n                  <jats:p>We investigated the effects of IMI in a rat model of EjD following hypogastric nerve (HGN) injury using apomorphine (APO)-induced ejaculations and lumbar splanchnic nerve (LSN) electrostimulation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Thirty-six male Sprague\u2013Dawley rats were divided into six groups: Sham, Sham-IMI, Crush-Vehicle, Crush-IMI, Cut-Vehicle, and Cut-IMI. In the Crush group, the bilateral HGNs were crushed, and in the Cut group, the bilateral HGNs were excised. IMI (1\u00a0mg\/kg) or Vehicle was administered intraperitoneally 7-30\u00a0days after HGN injury.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Outcomes<\/jats:title>\n                  <jats:p>Ejaculatory function was assessed weekly using the weight of solid semen ejaculated from the urethral meatus after subcutaneous administration of 0.5\u00a0mg\/kg APO. Changes in seminal vesicle pressure (SVP) were assessed using APO-induced ejaculation (\u0394SVPA) and LSN electrostimulation (\u0394SVPE) 30\u00a0days after HGN injury. Dunnett\u2019s test was used to determine significant differences between groups.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>In the Crush-IMI group, the mean solid semen weights significantly increased 21 and 28\u00a0days after HGN injury compared with those in the Crush-Vehicle group (P\u2009=\u2009.011 and P\u2009=\u2009.036, respectively). However, in the Cut-IMI group, no increase in solid semen weight was observed. The \u0394SVPA in the Crush-IMI group was higher than that in the Crush-Vehicle group; however, the difference was not statistically significant. Furthermore, \u0394SVPE in the Crush-IMI group was significantly higher than that in the Crush-Vehicle group (P\u2009=\u2009.024). Additionally, the mean seminal vesicle weights in the Crush-IMI group were lower than those in the Crush-Vehicle group at 30\u00a0days after HGN injury (P\u2009=\u2009.014).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Clinical Implications<\/jats:title>\n                  <jats:p>IMI improves SV function, suggested that IMI might be useful in patients with EjD.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Strengths and Limitations<\/jats:title>\n                  <jats:p>This study shows that IMI has an effect on EjD by improving SV function in a rat model.
