hello . im 18 years old and i had a varicocele operation about 2 months ago. ever since my operation the shape and from of my sperm has changed. before my sperm use to be very dense, thick and white . now my sperm is alot less dense and liquidy . my sperm is now a mixture of white and clear sperm , but mostly clear sperm . i am scared that i might not be able to have children any more. does anyone know why my sperm is like this now ? does it mean that i cant have children ? if i cant have children is there any way of reversing this ?will it ever be the smae again ? thank you
