The answer is no, sperm do not survive very long in male urine.
Once sperm come into contact with urine, the environment is generally hostile to their survival. The reasons for this include:
- Acidity: Urine is typically acidic, while sperm thrive in a more alkaline environment. The acidity of urine can kill sperm.
- Osmolarity: Urine has a different osmolarity (concentration of dissolved substances) than semen. This difference can disrupt the sperm's cellular balance and lead to their demise.
- Toxins: Urine contains waste products and toxins that are harmful to sperm.
While a small number of sperm might survive for a very brief period in diluted urine, the overall environment is not conducive to sperm viability or fertilization.
