Figure 4: Sensory threshold in IELT ≤1 min and IELT >1 min group. Sensory threshold of (a) warm, (b) cold, and (c) vibration in each location. The dot indicates the median and the whiskers indicate lower and upper quartile. No significant difference between IELT ≤1 min and IELT >1 min group (Wilcoxon rank-sum test). IELT: intravaginal ejaculation latency.
