Sperm cannot survive for long on hands after washing, even if the washing is not thorough.
Here's why:
- Sperm are delicate: Sperm cells are extremely fragile and require a specific environment to survive. They cannot withstand the harsh conditions on the skin, such as dryness, temperature changes, and the presence of soap and water.
- Washing removes sperm: The act of washing hands with soap and water effectively removes any sperm that may be present.
- Survival time: Even if some sperm cells manage to cling to the skin, they will likely die within a few minutes due to the unfavorable environment.
Therefore, washing your hands thoroughly with soap and water is sufficient to eliminate any risk of sperm survival on your hands.
