Low morphology

Ta
Hi I was wondering if anyone has any information for me on this. Basically my husband did a SA and it came back that his sperm count was good and mobility was good ( the doc wouldn't give me the exact percentage 😡) but he said that a lot of the morphology was abnormal. So his referred is to the fertility clinic. I live in the UK and they said it will take 3 weeks for an appointment to come through the post. But not sure how long the waiting list is. Does this mean it makes it difficult for us to get pregnant? 
Any information would be great ? What do we expect from the clinic next?
