This came up with me last week. Since my wife and I are older (40) we had some tests done to make sure we can have a kid (jerking off in the cup at the fertility clinic was kinda fun). The blood test my urologist had me take came up low on testosterone. He said after she gets pregnant he will prescribe me some test since it would make me sterile now.
He'll probably give me that gel shit, but after killing myself to get gear all these years its funny that I will get some legally now.
