Orchitis may be a cause of the sterility in the bull.

Pressure atrophy of the sper- matogenic cells and fibrosis of the entire testicle follows.
How do you bring a cow into heat?

Why my cow is not getting pregnant?
Anovulation, a term describing when cows fail to ovulate normally, can be a result of poor postpartum health but is also related to high milk production in the modern dairy cow. On average, anovulation persists in at least 20% of dairy cows beyond the common voluntary waiting period of 60 days (Wiltbank et al., 2010).
