How Does Sperm Morphology (Shape) Affect Fertility?

Couple Expecting a Baby


At our IVF Center Mumbai a fertility specialist will examine both partners if a couple is having problems getting pregnant or having a successful pregnancy. They will examine both males’ and females’ overall health as well as the reproductive organs. When it comes to the male partner, sperm morphology is critical for a successful pregnancy, whether it is spontaneous or achieved through reproductive treatments.

Sperm morphology is largely studied to determine a man’s reproductive status, as well as sperm count and motility. To understand this, our doctors at the Best IVF Hospital in Mumbai will do a sperm analysis test. The morphology of the sperm, or its form and size, is a crucial component in the test. The form of the sperm indicates that appropriate sperm development, or spermatogenesis, has occurred in the testicles. Males who have a deficiency in sperm maturation tend to have sperm shape issues, which might affect male fertility.


What is Sperm Morphology?

Sperm MorphologyThe shape of individual sperm is referred to as sperm morphology.

Sperm cells are divided into three parts: the head, neck, and tail. Each portion has its own “ideal” shape and number, and laboratory evaluation for sperm analysis include counting how many sperm have the correct number of heads and tails and what percentage have the correct shape, structure, and length.


Sperm Morphology Range

The usual range for sperm morphology is only 4 – 14%. Yes, you read that correctly. A successful pregnancy requires approximately 14% of the sperm to be of the proper shape and size.

According to Kruger criteria, fertilization is quite likely when sperm morphology is more than 14%. If it is less than 4%, which means the percentage of healthy sperm is less than 4%, it is an abnormal sperm morphology, and pregnancy may take longer. A comparable range is also recommended by the WHO.

Your fertility specialist can assist in determining the cause of the aberrant sperm morphology and correcting it with appropriate therapy.


How Does Sperm Morphology Affect Fertility? 

Fertilization requires proper sperm shape. If the sperm head is not appropriately formed, the sperm cell’s ability to merge with the egg is hampered. If a sperm’s tail is malformed, it may be less effective at propelling itself toward an egg as it travels through the female reproductive tract.


Other Sperm Parameters

Morphology is not the only aspect that might influence the quality of sperm. Many distinct sperm parameters, as well as a variety of other circumstances, might influence a person’s capacity to conceive. Male fertility is also affected by other factors, such as

  • The total amount of sperm in the sample, or sperm count.
  • Sperm motility refers to sperm’s ability to travel appropriately.
  • Semen volume, or the amount of fluid ejaculated by a person.

Other factors that can influence fertility include whether or not a person has any genetic abnormalities with their sperm cells, as well as the fertility of their spouse.


Reasons for Abnormal Sperm Shape

Every male will have a certain amount of sperm that is improperly produced. The range varies from person to person and is determined by the following factors:


Chemical Exposures

If you are constantly exposed to chemicals as a result of your job or the environment in which you reside, you may have a greater range of aberrant sperm morphology.


Testicular Temperature

The more heat your testicles are exposed to, the more likely it is that you may produce defective sperm.



Abnormal sperm morphology can also be a hereditary characteristic. Abnormal sperm morphology will go undiscovered unless a person analyses their sperm sample. As a result, determining this can be difficult.



Untreated infections can have an impact on sperm shape and quality.
