I gotta question.. Since about a year ago, the colour and thickness of my sperm changed considerably. It was white and normally thick as most people have it...but it changed to really see through, almost watery also in thickness. Can anybody tell me what the cause might be? I can't remember having changed my diet. I did start smoking approximately 5 sigarrettes a week, FYI. Otherwise, no major changes in diet. Thanx for helping me out, it kinda got me worried.
