Husband semen analysis

So the report below is showing 14% progressive motile sperm . I researched sand anything below 32 % for progressive is low so I think this is really low . The fertility doctor has prescribed him profertil . He also have low testosterone. The doctor at our last visit stated we are fine to keep trying naturally and come back to him in another 4 months if we don’t get succeed . I’m quite angry as I m no doctor but I wanted to go for <a href="https://glowing.com/glow-fertility-program">ivf</a> straight away yet he recommends to keep trying naturally? .My results have all come back normal . Anyone else got any ideas why he would say this when to me it looks pretty bad . I’ve had two chemical pregnancies so far .
