Cryptorchidism is in the genes, in the DNA. If the cow has only one bull every four years that has a testicle retained, then I understand not using him as a bull.
But all of the other bulls and heifers she gave birth to carry the same gene, they just slid by.
Each time you retain any of her offspring, or a bull's offspring, they carry the same gene, even if they were not born with the problem.
Where you will run into problems later, is when you start retaining your best heifers, and your bulls that carry the gene. Even if it seems more like line breeding instead of in-breeding, that gene stays with them.
As you breed each animal to the other, you increase your odds of it happening again.
Why don't you buy some good registered cows and a bull and start a small seed stock operation on the side to improve your herd. Make your own cows. Some like to buy them, but I like to customize them myself. They just don't always come out like you order them though. Take the heifers and put them into your herd. If one is outstanding, leave it in the seed stock group.
Purchase another super registered bull to put in with your cows of a different breed to cross with, that will pull your cows up, and start a really great cross bred herd. Get rid of the problems now before they take over your herd. The prices are good now, and get rid of the ones that are going to hurt you in the long run.
