that is something that cannot be determined "100%" via the internet since there is no way to blindly ascertain the extent of the injury. remember that the penis does not make sperm. the testicles make sperm. if you are concerned he would need to be examined by a medical professional or urologist. it would not be prudent to make a guess over the internet. i am sorry.
he got hurt in his penis tried ejaculating and could do it. will he be able to have children in the future for 100%? . so we were playing and i threw a ball into his direction and he got hurt in his penis. he stayed on the ground for some time and had pain for the next two days. he told me that he tried ejaculating after that and he could do that. is it 100% that he had no harm and that he can have children in the future? !
