A research group led by Dr Ege Serefoglu has published the results of a clinical study showing that modafinil (racemate) increases the ejaculatory time and improves the patient reported outcomes for patients with premature ejaculation (Tuken et al, “On-Demand Modafinil Improves Ejaculation Time and Patient Reported Outcomes in Men with Lifelong Premature Ejaculation”, Urology, August 2016) This study supports the finding in a previous case report (Serefoglu, EC “On-demand modafinil may be an effective treatment option for lifelong premature ejaculation: a case report” Andrologia, 2015) which examined the effects of on demand modafinil treatment on a 30 year old male patient with lifelong PE.
