ED and depression

Hi all, my husband had been suffering from depression since he was a young teen. About a year ago I finally convinced him to go to the dr. After several med attempts he started lexapro that has helped his mood immensely. Only problem is now he has difficulty getting an erection and finishing. We were hoping to try for baby #2 this summer. Anything he can try other than another prescription? He’s in his 30’s so it’s a bit embarrassing for him but I know it’s common when antidepressants involved. It’s frustrating for me because we can never really have sex. Thanks.
