Do Ejaculation Latency and Other Sexual Measures Differ Between Men With Lifelong and Acquired Premature Ejaculation?

To determine whether men with lifelong vs acquired premature ejaculation (PE) subtypes differ on their estimated ejaculation latencies (EL) and related sexual, relationship, and behavioral parameters.

Of 2679 men who responded to an online multinational survey about sexual health and met inclusion criteria, 540 reported "probable" or "definite" PE, as assessed by the Premature Ejaculation Diagnostic Tool. Lifelong and acquired PE subtypes were compared on multiple measures related to EL, as well as on sets of demographic, diagnostic, relationship, sexual behavioral, and sexual functioning measures during both partnered sex and masturbation.

Nearly 73% of men with PE in this sample reported the lifelong subtype. No differences emerged in EL measures between subtypes, even when parsed according to age. Specifically, men 37years or under with either definite lifelong or acquired PE reported ELs of 1.9 minutes (SD=1.3). For men over 37, lifelong ELs were 2.0 minutes (SD=1.3), acquired ELs 2.4 minutes (SD=1.4). While the lifelong subgroup was younger and reported lower erectile functioning, these differences occurred only in the probable PE group and not the definite PE group.

Our data do not support different EL criteria for men with acquired vs lifelong PE, as suggested by several professional definitions. Furthermore, differences in age and erectile functioning between the groups, often reported in clinical samples though not in our definite PE group, may be an artifact of the general health/patient characteristics that lead such men to seek medical assistance.
