I didn't look at the image, but if it shows all the anatomical detail, then it has to violate the TOS. Why? According to my limited medical knowledge, all the parts aren't fully visible in 100% of the population without complete arousal. Some are more or less visible, but not all the instances, all the time. Thus, one must err on the side of caution. But it's hard to describe the violation in any more detail without violating the TOS.
