Semen and sperm quality

29 May the concentration of spermatozoa should be at least 20 million per ml; the total volume of semen should be at least 2ml; the total number of spermatozoa in the ejaculate should be at least 40 million; at least 75 per cent of the spermatozoa should be alive (it is normal for up to 25 per cent to be dead); at least. 23 Apr Noticing a change in the amount you ejaculate, or your semen volume, can point to some serious health conditions. The World Health Organization (WHO) defines “the lower range of normal” as 15 million per milliliter. While it only takes one sperm to fertilize an egg, a higher amount of sperm in an ejaculate, the higher the odds that one of your swimmers will go for the gold and actually fertilize an egg. The range of million/ml.

Sperm are wonderful little cells and they can be loads of fun! For your enjoyment we've compiled some amazing facts about them. See our FAQ page for additional fun information.

How long can sperm live on environmental surfaces? They die as they dry out, so it depends on how quickly they dry. They also are killed by fresh water due to osmotic shock. Soap and detergents such as those used for laundering and hand washing also kill them, as these substances strip off the cell membrane of the sperm.

They are the haploid half of your life cycle so be careful where you leave them. Please notewhile sperm are relatively easy to kill on environmental surfaces, do not try to use water or detergents to kill them in the vagina or female reproductive tract.

In addition, water and detergent can be harmful to the tissues. This is not a good birth control strategy! The volume and content of the ejaculate depend on the length of time between ejaculations.

One would think that a big animal would have bigger gametes, Amount of sperm per ejaculation nothing could be further from the truth. The biggest sperm I have ever seen came from a fruit fly!

On the other hand, of the vast number of mammals humans have one of the smallest sperm cells, measuring only 40 microns long. Rats produce one of the largest sperm at microns long.

When we talk of mice and men we may be the bigger animals in the diploid phase of life, but it is the mice that have the bigger haploid Amount of sperm per ejaculation of life with micron long sperm. How many is enough? This question always comes up in regard to human fertility. If it takes only one sperm to fertilize and Amount of sperm per ejaculation, why does a low sperm count make Amount of sperm per ejaculation man infertile?

Twenty Amount of sperm per ejaculation still seems to be a lot, so why the problem? Only a small fraction of the sperm deposited in the woman's vagina end up in the uterus. From those that make it to the uterus, only a small Amount of sperm per ejaculation of those find their way to the oviducts.

Usually the egg is all the way up at the other end of the oviduct fallopian tube. Of those that are in the oviduct only a small fraction make their way from the lower to the upper oviduct.

So, in fact, the number of sperm successfully arriving at where the egg is located is actually very small. Another problem is that the egg is not just waiting to be fertilized by the first sperm to come along. The egg is usually covered by a thick layer of cells called the corona radiata that serve as a blockade to restrict sperm from getting into the egg. Sperm cells contain enzymes that break this barrier down. It may actually require an assault of many sperm to break down the corona sufficiently to let one sperm get through to the egg.

So the whole process is somewhat like a marathon run in a maze filled with mucus followed by Amount of sperm per ejaculation into Amount of sperm per ejaculation fortress. That one sperm that finally makes it is the champion of Mother Nature's triathlon. If you don't have enough competitors to start, none are left at the finish.

Modern in-vitro fertilization techniques can by-pass this selection process and achieve fertilization with much fewer sperm. Successful fertilization is now even accomplished with sperm that can't swim. This is accomplished by directly injecting sperm into the egg with a tiny glass pipette tube.

Only time will tell what bypassing nature's triathlon will do to the human gene pool. Oakland University Rochester, Michigan
