Husband semen count low after testosterone

I wondered if anyone else’s SO has had a semen analysis of basically zero after testosterone (common) and then taken Hcg and clomid to kickstart semen production? Doctor said it would take 3/4 months to work.... does anyone have any experience? We’re going straight to <a href="https://glowing.com/glow-fertility-program">IVF</a> for a number of reasons and figure he doesn’t need to super high count, surely I just need a few of his viable swimmers?! Any help appreciated, trying not to put pressure on him but really want to get on with it!!
