What is it about?
This study tested whether individuals with at least 1 copy of the short (S) or long (L)(G) allele of the serotonin transporter gene-linked polymorphic region exhibit a greater incidence of premature ejaculation compared with L(A)L(A) individuals.

Why is it important?
Premature ejaculation has been reported as the most common male sexual dysfunction with global prevalence rates estimated at approximately 30%. McMahon proposed psychogenic and biogenic causes of PE. The biological causes considered include penile hypersensitivity, a hyperexcitable ejaculatory reflex, increased sexual arousability, possible endocrinopathy, a genetic predisposition and central 5-hydroxytryptamine (5-HT or serotonin) receptor dysfunction.
