How do you know if a horse is infertile?

If a stallion spikes a fever just before or during breeding season or when being collected, he might be infertile until new sperm completes its production cycle. “It takes about 60 days for sperm development, so the stallion should be checked about 60 days after the fever incident to see if he is producing normal sperm again,” says Sheerin.

How can we improve the fertility of affected stallions?

Additionally, there is some evidence to suggest that sperm processing techniques can be used to improve the fertility of affected stallions. For example special gradients can be used to separate ‘good quality’ sperm from ‘poor quality’ sperm thus allowing us to breed each mare with semen that is enriched in sperm that are likely to be more fertile.

Does stress affect semen quality in horses?

“It often depends on the duration of the stress, so we need a good historical perspective when a stallion comes in for an examination and has reduced semen quality,” says Varner.
