Is it considered a sin to search medical websites that may contain nude or sexual images for the purpose of learning and acquiring medical knowledge?

Viewing images of awrat (private parts) and nude women is forbidden. If the information sought is not essential, or can be obtained through other methods free from Sharia prohibitions, then it is impermissible to acquire it in a way that involves looking at such images. However, if there is an urgent need for the information and it can only be obtained through this method, then it is hoped there will be no sin, with the obligation to guard one's gaze from these images as much as possible.
