This article discusses the psychological, behavioral, and physiological explanations behind premature ejaculation and possible treatments. The authors conclude that much more research, both medical and social, must be conducted.

To understand the sexual response patterns of men with premature ejaculation and erectile dysfunction, the authors compared genital and affective responses of sexually functional and dysfunctional men with 3 types of sexual stimulation: an erotic video, penile vibrotactile stimulation, and a combination of both. Genital response differed across both groups and stimulus conditions, with an interactive effect indicating that groups showed different response patterns depending on the stimulation. Affective responses also differed across groups and interacted with stimulus conditions. The combination genital and affective response was superior to either alone in distinguishing men with no sexual problems from those with erectile or ejaculatory problems (or both). These factors were particularly useful in discriminating men with premature ejaculation from those with combined premature ejaculation and erectile dysfunction.

Studies using Western samples have found that people with sexual problems attribute negative sexual experiences more to themselves whereas those without sexual problems attribute negative sexual experiences more to external factors such as the particular situation or even the partner. While attribution patterns vary across sex, age, dysfunction status, and generations, to date no studies have investigated how they might vary across cultures. We compared attribution patterns of (presumed) heterosexual/cisgender Pakistani women with varying levels of orgasmic difficulty (OD) on hypothetical scenarios presenting either positive or negative partnered sexual outcomes, with attributions to four possible targets: self, husband, situation, and relationship. Similar to previous research using Western samples, Pakistani women with greater OD were more likely than non-OD counterparts to blame themselves and their partners for negative sexual experiences. In contrast with prior research, for Pakistani women, attributions were distributed widely across all targets, including relationship factors (e.g., compatibility and communication). Specifically, Pakistani women tied their explanations for both positive and negative sexual outcomes more strongly to assessment of their relationship with their husband. The way in which women with sexual difficulties in non-Western cultures interpret their sexual experiences suggests the need for remediation strategies sensitive to socio-sexual scripts of the culture.

Criteria for delayed ejaculation (DE) rely on a long ejaculation latency (EL) time, lack of control/advancement regarding ejaculation, and associated bother/distress; yet, few studies have investigated these criteria in men who indicate the desire to ejaculate sooner during partnered sex. To help standardize criteria for DE by better understanding characteristics of men who desire to ejaculate sooner during partnered sex in terms of their EL, reported ejaculatory control, and level of bother/distress, as well as their perceptions of typical and ideal ELs for men in general and of ELs for men with premature ejaculation (PE). A total of 572 men recruited through social media responded to an online survey regarding their EL, as well as typical, ideal, and PE ELs of men in general. They also rated (i) their ability to control and/or advance ejaculation and (ii) their level of associated bother/distress. 4 comparison groups were then established: men with probable DE (with [DE1] and without [DE2] ejaculatory control issues), a reference group with no ejaculatory disorders, and men who identified as having PE. To demonstrate differences in EL, ejaculatory control, and bother/distress between men with delayed ejaculation and the control and PE reference groups. ELs for men with probable DE were twice as long as those with no ejaculatory disorders. When probable DE men were further subdivided into DE2 and DE1, differences were greater for the DE2 group. DE2 men also differed significantly from the reference group on ejaculatory control/advancement but not on bother/distress. Both DE and reference groups differed from the PE group. Using both EL and ejaculatory control are useful in distinguishing men with delayed ejaculation from men without delayed ejaculation. A sizable sample drawn from a multinational population powered the study, whereas the use of social media for recruitment limited the generalizability of findings. Both EL and ejaculatory control differentiate men with probable DE from a control reference group having no ejaculatory disorders. Differences in bother/distress did not emerge as significant. Implications for diagnosing men with DE are presented. Rowland DL, Cote-Leger P. Moving Toward Empirically Based Standardization in the Diagnosis of Delayed Ejaculation. J Sex Med 2020;17:1896–1902.

The ejaculation latency (ELT) criterion for men with premature ejaculation (PE), including its 2 major subtypes of lifelong and acquired, relies heavily on expert opinion, yet such information represents only one source of data for this determination; furthermore, information regarding ELTs for PE within specific subgroups of men (eg, gay, bisexual) has been lacking. To obtain data regarding men's lived experiences and expectations regarding typical ejaculation, ideal ejaculation, and PE and (for men) self-reported ejaculatory latencies during partnered sex across a variety a groups, including men vs women (ie, sexual partners of men), men with and without PE, and straight vs gay/bisexual men. We recruited 1,065 men and sexual partners of men, asking them to estimate typical ejaculation, ideal ejaculation, and PE and (for men) self-latencies through an online survey posted on social media. Demographics, sexual identity, and sexual response data were also collected. Typical and self-reported ELTs were closely aligned with those reported in the literature, with ideal ELTs generally longer than typical ELTs. Median PE ELTs were consistently estimated around 1.5 min, with nearly all subgroups—men vs women; straight vs gay; PE and non-PE men—showing alignment on this criterion. Men with lifelong PE did not differ from men with acquired PE in either their PE ELT estimation or their self-reported ELT. The data support the idea of extending the latency cutoff for establishing a PE diagnosis beyond the current 1-minute threshold. A large sample size drawn from a multinational population powered the study, whereas the use of social media for recruitment and lack of inclusion of lesbian and asexual individuals may have missed relevant data from some who have had sexual experience with men. Straight and nonstraight men do not differ in their ELT estimations. In addition, the use of different ELT criteria for lifelong vs acquired PE may be unnecessary. Côté-Léger P, Rowland DL.
