How can I find if my horse has sired any foals?

I own a 10 year old half Holsteiner half German warmblood horse with very good bloodlines. He was just gelded this past Oct./Nov. when he was imported to the US. My trainer and I thought he probably had foals floating around somewhere but weren’t sure how to find out for sure.

If he is registered then you can contact his registry. If he competed you might also find him and his progeny listed on Hippomundo or HorseTelex

I can take a look in the german database for Sport horses. If the horse was licensed in Germany and/or has competing offspring, it should be found there.

I Need Name and Pedigree of the horse. The german ID (“Lebensnummer” = Life number) would be helpful too.
