Goodness! Wherever did you get this literature? Semen is composed of Seminal
Fluid and sperm. Sperm is made in the testicles, while seminal fluid is made
in the seminal vesicles, two small glands attached to the vas deferens on
wither side. The seminal vesicles have no other known function; the testes,
of course, produce testosterone, but this does not seem to vary with frequency
of sex or ejaculation. The cerebrospinal fluid has no connection whatever
with ejaculation, and a good thing too: Even the removal of a few cc's of CSF
can give you a terrific headache due to traction on the meninges (the 
membranes around the brain and spinal cord), which is why they have you lie 
down after having a spinal tap. I'm glad you're skeptical about these ideas;
they are looney.
