conceiving tips

Sydney • Baby dust come at me
Ok so my partner knows he has only a 1 in 1000 chance of having a child. I want to try naturally for a while before Going to the fertility clinic and trying <a href="">IVF</a> 
Just wondering if any of you ladies might have any tips/tricks to boost the chances? 
I know that it's a low chance and a slow progress. I've already put in my mind I may not be able to have children naturally with him and I'm ok with that. There's other option for us out there. Just wanting some "old wives tales" or "tricks or tips" from ladies that have worked for them or they have heard.
