fructose is produced in seminal vesicle through polyol pathway which means reduction of glucose to sorbitol by aldose reductase with NADPH cofactor then the conversion of sorbitol to fructose by sorbitol dehydrogenase with NAD as cofactor and in this pathway there is no need of input energy (ATP).
seminal vesicles
fructose
Semen provides fructose for sperm.
metabolising enzymes are not there insemen for other carbohydrates
The epididymis.
The epididymis is the are where sperm fully mature as they receive fructose. This is a narrow tube that is tightly coiled.
The seminal vesicle contains a sugary substance that gives the sperm energy and the Prostate gland provides alkaline fluid which helps protect the sperm from the acidity of the vagina
The thick secretions from the seminal vesicles contain proteins, enzymes, fructose, mucus, vitamin C, flavins, phosphorylcholine and prostaglandins. The high fructose concentrations provide nutrient energy for the spermatozoa.
Fructose is a simple sugar occurring throughout nature. It is a source of energy used by the body. (ADP/ATP are used internally in the cells) The amount of fructose in any given ejaculate is directly proportional to the diet of the man in question. Simply put: fructose is an energy source and can be found in other bodily fluids.
Each sperm cell has a large tail which propels the cell forward.Embedded in the tail is the motor proteins that powers the locomotion of the sperm cell.Large number of mitochondria are also found which generates energy and that energy can be used to drive the motor pumps.
That is the mid piece. It gives energy for swimming
Mitochondria are in mid part of sperm.They gives energy to swim.
The seminal vesicles, which are accessory glands of the male reproductive system, produces fructose. This sugar is essential for the survival of sperm cells.
