How much ejaculate is released?

How Much Liquid is Released?
The amount of fluid released during ejaculation is reported to vary from a couple drops to almost two cups, 15 ounces [444 ml]. Two cups is a lot of liquid, can it really be that much? The average size of the female prostate is 1.3 inches long 0.75 inches wide 0.4 inches in height (3.3 x 1.9 x 1 cm). An elliptical container about this size when filled with water would hold 0.17 oz [5 ml] or 1 teaspoon. A cylindrical shape 0.75 inches across would hold 0.32 oz. If the female prostate can contain less than 0.4 oz where does the other 14.6 ounces come from? One study found women produced 30 to 50 ml [1 to 1.7 oz] [6 to 10 teaspoons] in 30 to 50 seconds. Okay, but 2 ounces is still a far cry from 15 ounces. Some believe the female prostate swells with fluid during sexual arousal, which would account for the greater volume of fluid. The prostate would need to increase in size by a factor of at least 9 if this is to be true. Interestingly enough the female bladder can hold about 16 ounces of fluid, and this is surprising close to the maximum amount of ejaculate reported.

Keep in mind the female prostate will continue to produce fluid for as long as a woman is sexually aroused, and as result a woman could produce more than 0.2 to 2.0 oz of ejaculate if multiple releases of fluid occurs. If the female prostate fills and empties at a rapid rate that would explain the larger volumes of fluid measured by some investigators. It would also mean the longer a woman's orgasm lasted the more she would ejaculate, as is often the case. If this is all true it is possible for a woman to ejaculate a considerable amount of fluid without it being liquid from the bladder. Obviously more research needs to be done to clarify this; perhaps using transvaginal ultrasound to observe the prostate during sexual arousal and orgasm.
