If you were half as smart as you think you are, you would know that the sperm count is in the millions, not thousands.
"-The force and amount of ejaculate vary widely from male to male. A normal ejaculation may contain anywhere from 2 to 15 milliliters (from half a teaspoon to a tablespoon), although 5 to 7 ml is typical. The amount of ejaculate is highly dependent on how recent the last previous ejaculation was within a range of the first two days. In other words, an ejaculation soon after a previous ejaculation will be very small, but will be much larger if ejaculation has not occurred for two days or longer. In some men, the more semen ejaculated the more pleasurable an orgasm they experience.-" Stop being a smartass.
Just so you know... that bit you posted regarding ejaculation has nothing to do with sperm count... If you weren't such an idiot you'd have searched wiki for semen or sperm, and not ejaculation, and you would have found out the average man produces 20 million sperm per 1 milliliter of semen, and that the average load size is actually 1.5 to 5 milliliters, thus 30 to 100 million sperm, not 10,000. Even on a near dry run where hardly nothing comes out, your producing more than 10,000 sperm.
