Squirting is the involuntary expulsion of fluid from the female urethra following stimulation of the anterior vaginal wall before or during orgasm. The mechanism underlying squirting has not been established.
To elucidate the mechanism of squirting.
The subjects in the current study were women who were able to squirt. They were not sex workers. A urethral catheter was inserted before sexual stimulation and the bladder was emptied. Then, a mixture of indigo carmine (10 ml) and saline (40 ml) was injected into the bladder. Sexual stimulation was provided to facilitate squirting, which was videotaped and verified. The secretions were collected in sterile cups, and prostate specific antigen (PSA) and glucose levels were measured.
Five women (2 in the 30s, 2 in the 40s, and 1 in the 50s) participated in this study. All women were able to squirt; three squirted only with manual sexual stimulation and two with penetrative sexual stimulation. The discharged fluid was blue in all cases, confirming the bladder as the source. The fluid was PSA-positive in four patients.
The main component of squirt fluid is urine, but may also contain fluid from Skene's glands (female prostate). This is the first report in which visualization of squirting was enhanced.
潮吹是指女性在性高潮前或性高潮期间，阴道前壁受到刺激后，尿道不由自主地排出液体。潮吹的潜在机制尚未明确。
阐明潮吹的机制。
本研究的受试者为有潮吹能力的女性。她们并非性工作者。在性刺激前插入尿道导管并排空膀胱。然后，将靛胭脂（10毫升）和生理盐水（40毫升）的混合物注入膀胱。提供性刺激以促进潮吹，并进行录像和验证。分泌物收集在无菌杯中，测量前列腺特异性抗原（PSA）和葡萄糖水平。
五名女性（两名30多岁，两名40多岁，一名50多岁）参与了本研究。所有女性都能潮吹；三名女性仅通过手动性刺激潮吹，两名通过插入式性刺激潮吹。所有情况下排出的液体均为蓝色，证实膀胱是液体来源。四名患者的液体PSA呈阳性。
潮吹液体的主要成分是尿液，但也可能含有斯基恩氏腺（女性前列腺）的液体。这是首次增强潮吹可视化的报告。
