We are trying again

okay Ladies so my husband and I had a miscarriage on November 2015 and we had done some test and found out my husband sperm was now swimming the wrong direction in 2016 but was told every 3 months the sperm is fresh again and can keep trying. Which vitamins do you suggest for both men and women when trying? I'm really hoping since this year is coming to an end and 2018 approaching it will be our year. I'm 29 now and scared my time is running out especially since I only have one ovary I lost the other one in 2014 but I haven't lost hope.
