Hi, I'm new to this site. I am a fairly new registered breeder. I bred my male & female for the first time a year ago Nov which was a success. Since then i've used him as a stud and he hasn't produced any successful litters. I was hoping it wasn't him but since it has been a year I recently bred him with my female again hoping there would be success again but her ultrasound was negative. It seems obvious that he is the problem. There is a reproductive specialist that can do a semen analysis but I just wonder even with that if he's proven sterile are there options for treatment? I appreciate any advice, Thank you
