Some time i feel pain on testicles may b it due to tight under ware i think testicles heat up some times
yup that can do it . I would avoid wearing overly tight underwear
I read that dead sperm also cause yellowish clr or puss cells in semen
Pus cells can but they should have been caught when they did your urinalysis testing
In urine report there is 2 or 3 pus cell
Less than 5 is considered normal and should not affect semen color
How i check my sperm are dead or not
To evaluate that you will need to look at your semen under a microscope to see if they are moving or not . ALSO there isn't a special stain called a live / dead stain made from a combination of Nigrosin and eosin that can be helpful too.... otherwise you will have to have it evaluated by a doctor
