The header is the most important thing. It must be personal to draw mens attention and engage them to enter the site
Can you try to reverse the image on the right side. My designer added this info:Very nice! My favorite is #18, but I prefer the hero image from #22. I like the clean open feeling of the layout. I also like that the welcome copy and the three buttons are "above the fold," meaning that's it not necessary to scroll down to get the user to navigate into the deeper pages. To increase the type size in each box, he may have to elongate the box, which may drop it below the fold. The other option would be for me to cut the copy down a bit -- maybe to just one sentence.
I don't think you need to talk about surgery up front, since this is more about information, support, and available options. I feel like it's not the right place to push the surgery choices; the deeper pages are better for that. If you wanted to put copy in the hero, a call to action to subscribe to the newsletter might be better.
I love the photo in front of the bay with the bridge/city in the background. You may be able to flip it so that he is on the right side of the page for the hero module
