Medical question about testosterone

I have stopped taking an anti-cancer drug because it robs me of my testosterone.

As a result, I am no longer able to walk to the post office, for example, with confidence. I assume that lack of testosterone makes me weak.

Before I started taking this medicine, I walked with absolute confidence.

The doctor has told me it takes about six months after stopping this medicine to regain my normal testosterone.

Question: Any suggestions on how to naturally increase my testosterone?

THANK YOU
