Another downside of TRT is that it greatly reduces male fertility by suppressing intratesticular testosterone. This is usually reversible by discontinuing treatment, but in rare cases it can be permanent. However depending on the cause of low testosterone (talk to your doctor), clomiphene citrate (clomid) can spur the testes to produce additional testosterone all the way up to the high normal range. So if you have low T and might want children in the next couple years, then look into that. I'm not a doctor, but from my basic undergraduate level understanding of biology I would expect clomid to be highly effective in cases where low testosterone is due to xenoestrogen exposure, among others.
