  • With every ejaculation, men produce around million sperm cells.

Fig 1. The journey begins with millions of sperm cells that are released into the female reproductive tract during intercourse. The sperm cells gain their full ability to swim when they are ejaculated into the reproductive tract [ 1 ],[ 2 ]. Upon ejaculation, the sperm cells are enclosed in a fluid called seminal plasma or semen, which is a mix of fluids from the testes, seminal vesicles, prostate, and the bulbourethral glands.

The fluid contains elements which protect the sperm cells during their journey towards the egg. Liquid extends from the cervix, allowing the sperm cells from the semen to swim into the cervix. Only the strongest sperm cells will make it this far. Once through the cervix, the sperm cells swim across the uterus and into the fallopian tubes as illustrated in figure 1. Fig 2. Of the millions of sperm cells deposited during intercourse, only very few have the potential to reach the fallopian tubes.

Once inside the tubes, the sperm cells follow signals a process called chemotaxis from the supportive cells called the cumulus cells of the egg.

On the way, the sperm cells undergo a series of biochemical and functional changes, which prepare the sperm cells for fertilization. Eventually, the sperm cells meet a barrier of cumulus cells surrounding the egg.

To pass this barrier the sperm cells now must undergo a process called the acrosome reaction , where enzymes are released from a deposit at the top of the sperm cell. These enzymes will break down the zona pellucida barrier, allowing the sperm to penetrate the egg [ 4 ], [ 5 ]. When inside the egg, both the egg and the sperm prepare for a genetic fusion.

After this, the 23 chromosomes from the egg and the 23 chromosomes from the sperm fuse to generate the 1 st cell that gives rise to new life, called the zygote. After fertilization, the zygote moves through the fallopian tube to attach itself to the inner wall of the uterus. Twin pregnancies happen either when two eggs are fertilised and attached to the uterus simultaneously dizygotic twins or when one fertilised egg splits into two embryos monozygotic twins.

With the ExSeed home sperm test, we assess how many sperm cells there are in a semen sample and how many of them are swimming. As you may see from the description above, these are important parameters in determining if the sperm cells will reach the egg.

They recognise it by two means: one is a thermal gradient.

They follow temperature so they know that the body gets warmer the further in they go. So they follow the thermal gradient. The second is that the egg oozes out various attractive molecules, in the same way that various inflammatory things attract the immune system in. This pulls the sperm towards the egg because they follow their noses, quite literally I underwent process and currently using Gonal F and my average sperm count is 20 to 40 millions and sperm morality is also above An adult salmon is typically 4 feet long.
