Sperm motility under microscope

There is considerable variability among species in what is considered normal or acceptable motility. A wet mount of diluted semen is prepared as described for a manual estimate, and sperm are photographed using an exposure time long enough for motile sperm to leave tracks across the image roughly 0. There is a noticeable lack of interest in being friendly to males. A bright field microscope can be used for evaluating motility if the field diaphragm is closed to enhance contrast and ability to visualize sperm. This is when the bitch is approaching estrus. Motility is also affected by periods of sexual inactivity - males that have not ejaculated for prolonged periods often have poor motility on the first ejaculate, but much better motility for a second ejaculate collected soon thereafter. It's a good idea to establish a base line of slides during proestrus.

A bright field microscope can be used for evaluating motility if the field diaphragm is closed to enhance contrast and ability to visualize sperm. Motility is also affected by periods of sexual inactivity - males that have not ejaculated for prolonged periods often have poor motility on the first ejaculate, but much better motility for a second ejaculate collected soon thereafter. A progressively motile spermatozoan moves forward in an essentially straight line, whereas a non-progressively motile sperm cell moves, but with an abnormal path, such as in tight circles tail chasing , fish flopping, and when normal movement is prevented by sperm head agglutination. Warmer temperatures increase sperm cell metabolism. Progressively motility is positively correlated with normal morphology in dogs. If estimating motility is a commonly required technique, a microscope warm stage may be worth purchasing.

    My boyfriend and i are at the point where we are probably going to have sex for the first time soon, I'm excited and want this but I'm also really nervous because I'm super self conscious about my body and especially the size of my chest. He's never seen me without a padded/pushup bra and I'm worried that he'll be disappointed. Is there anything i can do to get over this and not have it be an issue when we actually do sleep together?

    These two need to get together for real. She is so horny, she can't take her eyes off his big meat pole. He can squit out a load anytime she gets herself going. Love how she opened up her pussy for him.
