Fructose is the major energy source for ejaculated spermatozoa. It is produced
almost entirely in the seminal vesicles and is found in seminal plasma. The
determination of fructose concentration in seminal plasma therefore can provide
information about the secretory function of the seminal vesicles. It is especially
important to test for fructose if there are no sperm present, that is, if the semen
is azoospermic. The seminal vesicles are responsive to levels of circulating testosterone.
Seminal fructose is low in patients with low androgen levels and/or with congenital
absence of the vas deferens and/or seminal vesicles or possible blockage of the vas deferens.
There are many different methods for determining fructose in semen. The FructoScreen®
uses a method recommended by the WHO and described in their Manual.
