There are many things to prove Narutoverse is pretty modern, but I don't want to get into that.
ok the highest it gives him as of now is 30 and about 4 years since the beginnign of Naruto so that would make him 26 at the beginning and make him 15 when Naruto was born and we know and kakshi gaiden took place when he was 13 so that makes naruto born 2 years after that event .. so in the 2 years between the third war and the begin of naruto Minato was named Hokage so younger thatn 36 by like 5-8 years or so would make Minato around 18-19 at his death and he could have had narut o around the age of 17 and the fox was put into Naruto while he was less than 2 years old ...
what it boils down to is that Minato had Naruto between the ages odf 16-18 and was hokage iby his early 20's so if he can sire a child at that age who's to say that Tsunade couldn't be a teen mom as well
