Fructose, or fruit sugar, is a simple ketonic monosaccharide found in many plants, where it is often bonded to glucose to form the disaccharide sucrose. It is one of the three dietary monosaccharides, along with glucose and galactose, that are absorbed directly into the bloodstream during digestion.
Fructose may be absent in some congenital abnormalities of the male genital tract. It is produced in the male reproductive tract by the seminal vesicles. Fructose is the energy source for sperm motility. Its measurement is useful in investigation of azospermia, and it is used as a marker of the seminal vesicles. The use of corrected fructose levels is said to improve its diagnostic value. Corrected fructose is calculated by multiplying the log of motile sperm concentration by seminal fructose concentration.
- Seminal vesicle obstruction (in conjunction with low semen volume)
- Atresia distal to the seminal vesicles (in conjunction with low semen volume)
