An immature sperm is a "younger" sperm cell that lacks the characteristic features and functions of mature sperm . An immature sperm is immobile, so it cannot swim through the fallopian tube to reach the egg and does not have the ability to break down the wall of the egg to fertilize it (acrosome reaction) .
The spermatids are immature sperm cells that mature in the epididymis nurtured by the Sertoli cells . It takes about ninety days for the sperm to grow, mature, and finally be collected in the epididymis . Here the sperm become capable of motility . After each ejaculation, it takes about forty hours for the epididymis to refill with mature sperm .
In the body, at the same time, you will have immature sperm that are brand new that will gradually mature over the next couple of months as well as fully mature sperm . The idea would be to abstain for a few days (based on your doctors recommendation) to build up enough mature sperm in your ejaculate to determine a sperm count and motility .
