As a leading infertility specialist in Mumbai, One of our clinic’s most commonly asked questions is,
What does the 1% or 2% normal sperm in the report indicate?
Well, it has to do with sperm morphology.

When it comes to fertility and the ability to conceive, Sperm morphology plays a vital role.
So when your report indicates that your normal sperm count is 1% or 2%, the first step is to get a retest at the best laboratory.
Sperm morphology, in general, shows the visual appearance of the sperm. It gives identification to the sperm.
Structure of the Normal Sperm
Head :
It’s the first part of the sperm where its nucleus is present.
This is the region that stores genetic information or DNA and carries forward the traits of a father to his children. The cap that covers the sperm is called Acrosomal Cap.
Middle Piece :
This region is also known as the powerhouse of the sperm as it stores energy and acts as a battery for the sperm.
The medical term for this batter is Mitochondria.
Tail :
This is the part that helps the sperm swim and reaches the egg during sexual intercourse.
If there is some issue with any part of the sperm being defective, it is known as a defective sperm.

Formation of the Sperm cell
At this stage, the sperm cell is called Spermatogonia. It contains a nucleus and mitochondria even at this stage.
The nucleus is surrounded by the Golgi body. These spermatogonia grow into sperms in the testes.
After a few days, its shape starts changing. A small flagellum appears at the cell’s end, eventually growing into a tail.
At the same time, the nucleus moves in the frontal region, and the acrosomal cap surrounds the nucleus. Similarly, the Mitochondria, or the cell’s powerhouse, moves a little below.
Now,
If you are wondering how and why these cells change their structure, then the answer is Testosterone. Testosterone is a male reproductive hormone that’s responsible for this conversion.
Gradually, the structure of sperm cells changes. The Golgi body starts covering the nucleus, forming an acrosomal cap shortly.
Understanding Sperm morphology is critical, especially for those trying to conceive but unable to do so.
A lot of patients are misguided that if their sperm morphology report is bad, i.e. the structure of their sperm cells is defective, they cannot conceive naturally. They must use an ART(assisted reproductive technique) to conceive a child.
But that’s a wrong belief. Even if 95 to 98% of your cells are defective, you can easily conceive naturally.
