Increasing male fertility, any luck?

Has anyone had any luck with increasing male mobility and morphology with natural resources?

My fiancé and I are going to try for 4 months to increase his mobility/morphology with diet, weight loss, and male fertility supplements before <a href="https://glowing.com/glow-fertility-program">IUI</a> or <a href="https://glowing.com/glow-fertility-program">IVF</a>.

I’d love to hear your thoughts and success stories
