Male Fertility Concern

Hello - need a bit of advice! So my partner has been on a Stag Do (Bachelor party) which involved heavy drinking! I'm really concerned about TTC this month in case the heavy drinking from the male side can affect the baby if we are lucky enough to conceive this month! Does anyone have any experience/ideas on this? I have tried to google but it just says drinking can affect sperm count! He's been taking all of his vitamins (as have I) and I haven't had a drop of alcohol since we started TTC. Any views would be appreciated! Baby dust to all! 🍼🍼
