Seminal vesicles
are connected to the vas deferens which transport sperm
to them before ejaculation. Seminal vesicles make up
the bulk of the ejaculatory fluid. After adding fluid
to the sperm, the liquid is transported to the prostate
gland. The prostate gland adds hormones and proteins
which nourish the sperm and keep them alive long enough
to reach an egg. The prostate gland also adds an anti-coagulant
which helps keep the ejaculatory fluid from congealing.
Removal of the seminal vesicles during prostate cancer
treatment, along with the prostate gland in radical
prostatectomy, can cause dry orgasm. Men experience
the same sensations associated with a normal orgasm,
but do not produce ejaculatory fluid.
