I have no idea who that is
I love the name MathJew Canning though, LOL.
To answer your question, Darren - yes, absolutely you can conceive while on steroids.
Flex Wheeler did it, for example. Ronnie Coleman is another example. It's not like most pro bodybuilders in general have children [from what I can tell - presumably, they are too absorbed in their careers], but the prior two examples I chose to mention because both were prolific fornicators.
I think in 2012 [or maybe 2011] when Dave Palumbo asked Ronnie Coleman how many kids he had, Ronnie answered something close to "I don't know...7 or 8", LOL.
Just one thing though, Darren:
Supposedly, whilst on steroids, there is a higher probability of having baby girls. That could be BS though...or just online conjecture or broscience, or what have you. I did read that online, but never saw it scientifically validated or anything.
But YES, you can absolutely conceive whilst on gear, despite it working as a birth control for some men.
