user3971: I've been trying to avoid going "all out medical" on any of my answers, as I think that's more in line with the theme on the site.  However, on this question, I didn't really think there was a good way to answer the question without graphic and possibly disturbing images.  
While not disturbing to me, I know people (like my wife) who are greatly disturbed by such images.  This may be the only SE where it is likely to content that could be both appropriate and also offensive.  What sort of warnings should we put up.  I noticed on my larger monitor in my office that by the time my warning loaded, the surgical images could be seen.  Therefore it might have been useless.
Thoughts?  
Also, as someone from possibly the other side of the wave, I feel all of medicine can really fall under the umbrella of biology (but clearly asking for medical advice isn't).  I feel like we still feel shaky on medical topics.  That's probably because there are few here with medical expertise, and as I mentioned in chat, most professionals I float this by would consider it an additional step (lit reviews being our bread and butter).

user3624: I don't have a problem with these images personally, and think that they have their place on a biology site. I also do not see a problem with this particular question per se, even if it could (worst case) be a reformulared 'personal medical question'. 
A disclaimer is a good idea though, since some people are disturbed by such images. My suggestion is to add a disclaimer directly to the quesiton title. Then readers can clearly see it before they open the question, and therefore avoid the images. This would solve the issue of large screens that you mention, but also cases were the images are useful directly in the question. Since this issue does not come up that often (at least not at the moment) this should be fairly unproblematic, and would not clutter the main page.  

user6: I'd usually put such images behind a link instead of embedding them into the post. Then everyone can decide if they want to look at them.
In this specific case I think those are too many images and it would get rather annoying to click through to every single one. So I think the warning above is probably the best way to do it, even though it is not perfect.

user4788: Another option - if the spoiler markup isn't sufficient - is to convert the images to monochrome. The majority of graphic images will still be informative without the red ichor that turns a lot of people off.
Compare and contrast:
Normal

 

Black and White

Re-saturated monochrome hue shifted to the colour of vegetation (Green)


user69: This seems like a good use of the spoiler markup for Biology (didn't see that one coming!).
