Is 7% sperm morphology good?
Below are the Kruger Strict Criteria scores and their explanations: Over 14 percent of sperm have normal morphology – high probability of fertility. 4-14 percent – fertility slightly decreased. 0-3 percent – fertility extremely impaired.
What is considered low sperm morphology?
If less than 40 percent of your sperm are motile, your considered to have low sperm motility. In addition to sperm motility, your doctor can also use a semen analysis to test: the health of the male genital tract.
What is normal morphology Kruger?
The strict morphology score is a result that indicates and predicts the sperm’s potential for fertilization: Strict morphology score over 14 % normal: (normal; fertilizing capacity excellent) Strict morphology score 4-14 % normal: (abnormal; possibly decreased or impaired fertilizing capacity)
What is abnormal sperm morphology?
Normal sperm have an oval head with a long tail. Abnormal sperm have head or tail defects — such as a large or misshapen head or a crooked or double tail. These defects might affect the ability of the sperm to reach and penetrate an egg. However, having a large percentage of misshapen sperm isn’t uncommon.
What is normal sperm analysis report?
A semen analysis tests for the following: number of sperm (volume) shape of sperm. movement of sperm, or “sperm motility”…Semen analysis results table.
| WHO reference range | |
|---|---|
| Total sperm count in ejaculate | 39–928 million |
| Ejaculate volume | 1.5–7.6 mL |
| Sperm concentration | 15–259 million per mL |
Can IVF work with low sperm morphology?
Abnormal morphology (shape of sperm) has been linked to poor fertilization. Therefore, some clinics will recommend ICSI for men with poor sperm morphology.In IVF, fertilization can be achieved through one of two ways: insemination or ICSI.
What causes poor morphology in sperm?
There are many factors that can lead to the formation of sperm with an abnormal morphology. Genetic traits, exposure to toxic chemicals, increased testicular temperature and infection can cause abnormal sperm morphology. The most common cause is attributed to abnormal morphology (shape).
Is 20 sperm motility normal?
What Is a Normal Sperm Motility? A total motile count of over 20 million is considered normal. However, even if you have more than 20 million motile sperm, it may not result a higher chance of pregnancy. If you have fewer than 20 million motile sperm, your chances of having a successful pregnancy go down.
Is 30 sperm motility good?
If the test sample shows that less than 25 to 30 percent of the sperm move forward progressively, the motility is considered low.
What is a good sperm morphology?
The precise range can vary, but typically a normal or healthy sperm morphology range is between 4 and 14 percent NF. A score below 4 percent may mean it takes longer than normal to achieve pregnancy. A result of 0 percent NF usually means in vitro fertilization (IVF) may be necessary for conception.
What is normal morphology?
A smooth, oval-shaped head that is 5-6 micrometers long and 2.5-3.5 micrometers wide (less than the size of a needle point) A well-defined cap (acrosome) that covers 40% to 70% of the sperm head. No visible abnormality of neck, midpiece, or tail.
Can you conceive with 0 morphology?
In summary, men with a complete absence of NF (0%) on strict morphology exhibit high rates of success without IVF. As such, strict morphology should not be used to predict fertilization, pregnancy, or live birth potential. In men with 0% NF, alternative modalities should be considered before immediate IVF.
Is 50% sperm motility normal?
What is abnormal morphology of sperm?
Abnormal sperm have head or tail defects — such as a large or misshapen head or a crooked or double tail. These defects might affect the ability of the sperm to reach and penetrate an egg.
Is 70 sperm motility good?
Sperm motility, or the ability to move rapidly: 60% to 80% actively moving. Sperm morphology, or the sperm’s shape and size: 70% to 90% normally shaped.
What are the causes of abnormal sperm morphology?

What causes misshapen sperm?
– Infections – High fever – Usage of illegal drugs – Alcohol consumption – Congenital testicular abnormalities – Varicocele – Enlargement of veins within the scrotum – Toxin exposure causes reduced sperm motility – Cigarette smoke causes abnormal morphology – Organic solvents causes coiled tails
