Pls. tell a little exactly how sperm in the testes is being reabsorbed or recycled. i think i have dead sperm in my testes due to 2x lung xray. ?

With ejavulate: All sperm are ejected with each ejaculation. Live or dead. Exposure to small amounts of x-ray have no long term effects. Do nothing. Don't worry.

Unlikely: Many cells in your body go through a process called programed cell death (apoptosis), including sperm, blood cells, etc.). This is based on their life span. The cells simply break down. The amount of radiation in 2 chest xrays is less than the amount of radiation you receive from environment every year, and not enough to cause any damage.
