A stallion used for breeding is known as a stud.
Most yearlings and two-year-olds can and will breed under good circumstances. There's probably not a horse practice without a firsthand story of the pregnant filly that was only with a colt until a year of age. So for sure, many fairly young colts can be fertile.
Stallions will typically remain fertile beyond their 20th year of age. The age that stallions stop producing spermatozoa will vary between stallions. It is important that semen is routinely evaluated on all stallions, especially when using older stallions because of the expected decrease of semen production with age.
