A short frenulum can present in various grades of severity, and its diagnosis may depend on the subjective criteria of evaluation at physical examination in a medical office as there is no standard definition. Frenulum restricts the movement of the prepuce, even when not causing obvious phimosis. When the foreskin is completely retracted over the glans, a short frenulum tugs down the glans. One study arbitrarily defined a “short frenulum” as that which causes a ventral curvature of the glans major of 20° or more upon gentle retraction of the foreskin in the clinic. Short frenulum in this study was a common cause of premature ejaculation, and frenuloplasty significantly improved the ejaculation latency. Short frenulum may be more sensitive in subjects with premature ejaculation. Also, due to the limitation of the length of frenulum, and for the fear of pain, the strokes during Sexual intercourse may shorter, but faster, thus leading to early ejaculation.
