Q: My boyfriend's ejaculate looks funny. What does that mean?

A: Just by looking at it, smelling it, feeling it, or tasting it, the average person can't really assess whether the ejaculate is fertile or not.
The best way to examine the quality of the ejaculate is by examining it in a laboratory -- doing a spermanalysis. The spermanalysis checks the amount of the ejaculate, the amount of spermatozoa (sperm) per cc, as well as assessing the shape and movement of the spermatozoa.
If you think that should be done, your boyfriend could have the test done and be reassured that everything is OK.
