bindyboop my sister is also a naturopath and has given me a world of information in my quest to become a mum and my partner a dad.
I assume your husband has done a sperm analysis previously. We were advised to stay off alcohol, coffee, I took In Natal a multivitamin, fish oil and vitamin D. Your partner can be doing the same and also zinc tablets which is good for sperm quality and coq10. Sperm is generated in around 80 days so its good for three months to stick to that. Am sure you both want the sperm health to be in as best a condition as possible. Good luck.
