. . . if you want to be able to see sperm in semen?
My boyfriend has, in passing, expressed a desire to examine his own sperm under a microscope, and it’s never too early to plan for Christmas presents. Unfortunately I know nothing about microscopes. I was surfing around and found some cool-looking USB microscopes - does anyone know anything about those?
Microscopes are more about the quality rather than the power overall. The cheap ones sometimes promise high magnification but poor field of view or picture quality even under a lamp. 400x magnification is recommended as the the minimum for good human sperm viewing. I did this experiment myself at a lab in college. I was convinced I was infertile for some reason and proved to myself rather quickly that I was about the opposite and later real life results with kids on demand proved that. Of course someone walked in while I was oogling mine and asked to see what I was looking at. Tell him to be careful. Lab quality microscopes are very expensive for a reason. You might be better off just borrowing one from a school if that is the main reason he wants one.
