This answer all depends on the boy himself. Not all boys hit when they are twelve years of age. Some boys hit puberty earlier, and some later. When a boy is going through puberty, and has started to produce sperm, day and night, around the clock, the testicles constantly produce sperm. Therefore it is also extremely hard to get an accurate count.
most 12 yr olds produce little or no sperm. Usually sperm production is preceded by clear fluid, which is semen. Even when fully mature, some men can produce only small amounts of semen and some can produce large amounts. The amount is really not important, since it only takes one sperm cell to do the job.
