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. The female tract and the jelly-like consistency of human semen protect them from mixing well with water once inside the female body.
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. The average volume of semen is 2. Both quantity and quality of the sperm are important determinants of fertility. Just remember though- it only takes ONE to make a baby. The volume of a single ejaculate has declined from 3. This means that men on average are now ejaculating less than half the number of sperm as men did 50 yrs ago.
A drop from more than million sperm to about million sperm per ejaculate. Furthermore, the number of motile sperm has also dipped.
Importantly, the sperm count has not declined in the less polluted areas of the world during the same time period. Ukrainian translation courtesy of Anna Matesh.

In other words the amount of time it takes for sperm to get where they need to go. Average volume and content of human ejaculate. Fertile Life of Sperm hours. Motile moving sperm have been found in the human fallopian tube up to 85 hours Amount of sperm per ejaculation coitus, although the ability to fertilize an egg is usually lost before motility is lost.
One would think that a big animal would have bigger gametes, nothing could be further from the truth. The biggest sperm I have ever seen came from a fruit fly! The sperm of a fruit fly can be as long Amount of sperm per ejaculation the body of the male fly, about 1. 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 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 why does a low sperm count make
Amount of sperm per ejaculation man infertile?
A fertile male human ejaculates between 2 and 5 mililiters ml of semen on average about a teaspoon. In each ml there are normally about million sperm. If the concentration falls below 20 million sperm per mililiter there is usually some trouble with fertility.
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 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.
We don't know for sure but this may be a way of selecting for a healthy sperm to do the job of passing genes to
Amount of sperm per ejaculation next generation.
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
