Did he feed me a banquet of BS?

Hi everyone I hope all is well. Need opinions here. Quick info about me I am not too wise when it comes to men so here it goes. I am sterile & I hooked up w/ a "friend" that I haven't told all my business to. He had a few drinks & before the deed he asked me if I could get pregnant. I said "No." That was about a month or so ago. Well the other night we were talking & he had said he had, had his nuts cut about 2 years ago. I was like "What?" I didn't say anything but that obvioulsy that has me a wee bit concerned. He doesn't remember asking me if it was possible for me to get me knocked up. If he's gonna lie about that then he'll lie about anything. So...do you think his nut's are cut or is he still intact???
