So - I have been curious to see if this was possible and I've tried a couple of times. I'm going to spare you for the dirty details and jump straight into what I have seen. lol First time - a couple of months ago I couldn't see much, it almost looked like my saliva when I'm not ferning. Now, we have put hubby on super zinc supplements, and I could see loads of super tiny things in the fluid...lol! I think I could see some of them moving, but as the microscope is only 40x - it is not easy to say if it was sperm cells or what. I'm thinking about buying a microscope for children as I think they are better than this one...lol! Sorry if anyone thought this was groce - I just felt like sharing!
