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 morphology easy definition?

Can you get pregnant one morphology?
Sperm morphology alone does not determine whether or not a man can father a child. In fact, a study done by Kovac et. al in 2016 found that 29.2% of men with 0% morphology were able to conceive naturally, compared to 55.6% of men in the control group with normal morphology (≥4%).
What is normal range of sperm count?
Normal sperm densities range from 15 million to greater than 200 million sperm per milliliter of semen. You are considered to have a low sperm count if you have fewer than 15 million sperm per milliliter or less than 39 million sperm total per ejaculate.
Does IVF work with low sperm count?
Sperm with poor motility can still be used to fertilize eggs through IVF. By placing sperm and egg in close proximity in a petri dish, the poorly motile sperm do not have to travel far to reach the egg and fertilization is controlled in the lab. Low sperm counts can still achieve fertilization through IVF.
What is the morphology?
Morphology is the study of the internal structure of words and forms a core part of linguistic study today. The term morphology is Greek and is a makeup of morph- meaning ‘shape, form’, and -ology which means ‘the study of something’.
What causes low sperm morphology?
Poor Sperm Morphology Treatment 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).
Does morphology cause birth defects?
Issues with sperm morphology pose a number of problems for people who would like to have a child of their own. In broad terms, sperm morphology affects the motility of the sperm and can also increase risks of birth defects and serious health disorders.
