According to the World Health Organization:
- 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 30 per cent of the spermatozoa should be of normal shape and form.
- At least 25 per cent of the spermatozoa should be swimming with rapid forward movement.
- At least 50 per cent of the spermatozoa should be swimming forward, even if only sluggishly.

When a male does not produce sperm at the normal amount?
He needs to see a urologist.
In producing eggs and sperm why must DNA be divided to half its normal amount in somatic cells?
Tghe DNA in eggs and sperm must be divided in half so that when they later join together as a fertilized egg the egg has a normal amount of DNA
What is the size of sperm?
In a table spoon ( normal amount of sperm) there is 2-400 million siemen. So sperms are very very very microscopic
How does fertilization restore the normal chromosomen number?
Each gamete, the sperm or the egg, is haploid and contains half the number of chromosomes of a normal cell. When the sperm and egg combine to form a zygote, the zygote becomes a diploid cell with the normal amount of chromosomes.
Is normal saline sperm friendly?
No, normal saline is not considered to be sperm friendly. Because of the ingredients and chemicals in saline, it will kill sperm on contact.
What is normospermia?
normal sperm count with normal motilty
Which is a difference between meiosis I and meiosis II?
in meiosis one crossing over occurs and only two daughter cells are created with the normal amount of chromosomes. though in meiosis II those two daughter cells create another two cells and this time they are haploid not diploid with only half of the normal amount of chromosomes. this is because meiosis mainly occurs in sex cells such as sperm and eggs. they are created with only half the normal amount of chromosomes so that when a sperm and egg fuze to form a zygote, they have the normal amoujnt of chromosomes
Is it normal for sperm to be yellowish or a beige like color normal if not why?
Yes yes it is normal
Is it normal to produce sperm when during excretion?
yes it is very normal
What is a normal gamete?
A gamete is a specialized cell that contains half of the DNA of the parent organism. Since the structure of gametes for different species can vary considerably normal would be any gamete thatcontains the correct amount of DNA and is capable of fertilization.If sperm is used as an example, normal would be those sperm that have the correct amount of DNA, are progressively motile and have a morphology(form/structure) that will allow them to fertilize the egg once it is reached.
Can you still produce sperm with azospermia?
Whether a person with azoospermia can produce sperm depends on the type of azoospermia they have. People with pre-testicular azoospermia usually make very little if any sperm. People with testicular azoospermia may make sperm, but again the amount is minimal. People with post-testicular azoospermia may make normal amounts of sperm, but it cannot be ejaculated.
What amount of sperm is required to make a woman pregnant?
One sperm cell
