Effects of paroxetine on intravaginal ejaculatory latency time in Egyptian patients with lifelong premature ejaculation as a function of serotonin transporter polymorphism.
Premature ejaculation (PE) is a common ejaculatory complaint. The estimated rates among Turkish men reached 20%, although the severest type of PE (lifelong PE) usually does not exceed 2.3%. This could be seen in line with two survey studies involving five nations. They revealed that 2.5% of men had an intravaginal ejaculation latency time of <1 min and 6% of <2 min. Rapid ejaculation may be treated pharmacologically with a variety of different medications that act either centrally or locally to delay ejaculation and subsequent orgasm. Antidepressants, particularly members of the selective serotonin reuptake inhibitor class, retard ejaculation significantly. Recently, it was postulated that men with lifelong PE might result from a combination of polymorphisms of the serotonergic transporter and receptors, and other neurotransmitters and/or receptors. Our findings augment the significant effect of paroxetine in delaying ejaculation in the responders (P<0.001). Meanwhile, the findings do not suggest a positive association between such response and serotonin transporter gene promoter polymorphism.
