I have been using a relatively cheap microscope (My first Lab Microscope) to look at a sample of my semen. Under 40x magnification I see a lot of motionless sperm and generally not enough sperm floating about compared to what I see from other microscope videos of sperm floating (no pun) on the internet. It got me a little worried although I might be doing something wrong. I am wondering if the heat from the lamp is not killing the little guys before I get a chance to peek at them. I use slides with the cover glass, but sometimes I just place a sample on the slide without the cover glass because I want to see if I am doing something wrong. I would be interested to know from anybody more knowledgeable if there is something that can be improved in my steps. It is hard to give advice this way but I will answer any questions.
