Women expel fluids of various quantities and compositions from the urethra during sexual arousal and orgasm. These are classified as either female ejaculation (FE) or squirting (SQ). The aim of our analysis was to present evidence that FE and SQ are similar but etiologically different phenomena. A review of studies was performed on fluids expelled from the urogenital tract during female sexual activities using the Web of Knowledge™ (Web of Science Core Collection) and MEDLINE (Ovid) databases from 1946 to 2021. Until 2011, all female orgasmic expulsions of fluids were referred to as FE. The fluid was known to be either from the paraurethral glands or as a result of coital incontinence. At present, SQ is considered as a transurethral expulsion of approximately 10 milliliters or more of transparent fluid, while FE is considered as a secretion of a few milliliters of thick fluid. The fluid in SQ is similar to urine and is expelled by the urinary bladder. The secretion in FE originates from the paraurethral glands and contains a high concentration of prostate-specific antigen. Both phenomena can occur simultaneously. The mechanisms underlying SQ and FE are entirely different. SQ is a massive transurethral orgasmic expulsion from the urinary bladder, while FE is the secretion of a very small amount of fluid from the paraurethral glands.
女性在性唤起和性高潮期间会从尿道排出各种量和成分的液体。这些被分为女性射精（FE）或喷射（SQ）。我们分析的目的是提出证据表明 FE 和 SQ 是相似但病因不同的现象。使用 Web of Knowledge™（Web of Science 核心合集）和 MEDLINE（Ovid）数据库，从 1946 年到 2021 年，对女性性活动期间从泌尿生殖道排出的液体进行了研究回顾。直到 2011 年，所有女性性高潮时排出的液体都被称为 FE。这些液体要么来自尿道旁腺，要么是因为性交失禁。目前，SQ 被认为是一种大约 10 毫升或更多透明液体的经尿道排出，而 FE 被认为是几毫升稠厚液体的分泌。SQ 中的液体类似于尿液，由膀胱排出。FE 中的分泌物来自尿道旁腺，含有高浓度的前列腺特异性抗原。这两种现象可能同时发生。SQ 和 FE 的发生机制完全不同。SQ 是一种来自膀胱的大量经尿道性高潮性排出，而 FE 是尿道旁腺分泌的少量液体。
