How much spurm can a 11 year old let out?

At 11 years old, most boys have not yet reached puberty and therefore are unlikely to produce sperm. Puberty typically begins between ages 9 and 14, and sperm production usually starts a few years after the onset of puberty. Each individual's development can vary widely, so there's no set amount of sperm that can be expected at this age. If you have more questions about puberty or sexual health, it's best to consult a trusted adult or healthcare professional.
