In order to identify male infertility semen analysis is the first test that is ordered. In this assessment, certain physical characteristics like quantity, volume of the ejaculate, time taken to liquefy, pH, and the level of fructose is taken into consideration. Fructose is the basic source of energy that helps in the movement of the sperm cells. It also helps in their emergence, development, mobility and vitality. It is produced in the seminal vesicles under the control of androgens and from there it gets into the sperms. Any deformities in the formation and functional disorder of the seminal vesicles or the amount of hormones would lead to reduction in the level of fructose.
