Which point is located at the perineum, midway between the anus and the scrotum in men, and the anus and the posterior labial commissure in women?

Which point is located at the perineum, midway between the anus and the scrotum in men, and the anus and the posterior labial commissure in women?

• A. CV 2
• B. CV 3
• C. CV 4
• D. CV 1

Answer: (D)

This question tests locating a point on the Conception Vessel by precise anatomical landmarking. The lowest point along this vertical midline is Huiyin, Conception Vessel 1. It sits in the perineal depression between the anus and the genitals—between the anus and the scrotum in men, and between the anus and the posterior labial commissure in women. That exact perineal location is what the prompt describes, so Huiyin is the correct point. The other points on the same vessel lie higher up in the pubic region or abdomen, not at the perineum, so they don’t match this location.
