Although the lifelong and acquired subtypes of premature ejaculation (PE) have long been acknowledged, other putative PE subtypes have garnered less consideration.
This study aimed to describe a potentially unrecognized form of PE characterized by episodic or intermittent symptomology rather than regular, consistent symptomology.
From an online sample of 409 men with PE, 31 identified as specifically having intermittent PE (IPE) rather than either lifelong PE (LPE) or acquired PE (APE). Data regarding PE symptomology-including lack of ejaculatory control, foreplay time and estimated ejaculation latencies (ELs) during PE episodes, foreplay time and estimated ELs during non-PE episodes, and other sexual characteristics-were collected to better describe and understand this group of men.
Determination of sexual and ejaculatory response characteristics of men with IPE.
Men with IPE exhibited PE-typical responses during 40%-90% of their partnered sex episodes (mean ≈ 70%). Depending on the type of partnered sex, mean EL responses during PE episodes ranged from anteportal ejaculation to ~2 minutes, whereas mean EL responses during non-PE episodes ranged from ~3 to 6.5 minutes (P < .001). EL comparisons were also made across types of partnered sex and masturbation.
Some men exhibit PE-like symptoms, but do so only episodically or intermittently, a pattern that would technically prevent them from receiving treatment for PE according to most professional PE definitions.
This study is the first to detail the sexual and EL characteristics of men who experience PE intermittently. The limitations include issues regarding generalizability due to the relatively small sample size and the inherent bias possible in online studies about sexuality.
Men with IPE show all the characteristics of men with LPE and APE, except in the consistency with which their symptoms are manifested. Such men would qualify for treatment under ICD-11 guidelines but not under other professionally based diagnostic criteria.
尽管早泄（PE）的终身性和获得性亚型早已得到认可，但其他假定的PE亚型却较少受到关注。
本研究旨在描述一种可能未被认识到的PE形式，其特征为发作性或间歇性症状，而非规律性、持续性症状。
在409名患有PE的男性的在线样本中，31人被确定为特别患有间歇性PE（IPE），而非终身性PE（LPE）或获得性PE（APE）。收集有关PE症状的数据，包括射精控制能力缺乏、前戏时间以及PE发作期间的估计射精潜伏期（ELs）、非PE发作期间的前戏时间和估计ELs，以及其他性特征，以更好地描述和了解这群男性。
确定IPE男性的性和射精反应特征。
IPE男性在40%-90%的性伴侣性行为发作期间表现出典型的PE反应（平均约70%）。根据性伴侣性行为的类型，PE发作期间的平均EL反应范围从前门射精到约2分钟，而非PE发作期间的平均EL反应范围从约3到6.5分钟（P <.001）。还对不同类型的性伴侣性行为和自慰的EL进行了比较。
一些男性表现出类似PE的症状，但只是偶尔或间歇性出现，根据大多数专业的PE定义，这种模式在技术上会使他们无法接受PE治疗。
本研究首次详细描述了间歇性经历PE的男性的性和EL特征。局限性包括由于样本量相对较小以及在线性取向研究中可能存在的固有偏差导致的普遍性问题。
IPE男性表现出LPE和APE男性的所有特征，只是症状表现的一致性不同。根据国际疾病分类第11版（ICD-11）指南，这类男性有资格接受治疗，但不符合其他基于专业的诊断标准。
