What's wrong with sperm malformation? Does it affect pregnancy?

One or more of the head, body and tail of sperm have morphological variation and become abnormal sperm. However, abnormal sperm is less than 50% of normal sperm, that is, more than 50% of abnormal sperm in semen. Abnormal sperm refers to the morphological variation of the body and tail, and head deformities include giant head, amorphous head and double head. Physical deformities include thick, cracked and incomplete bodies; Tail deformity includes curly tail, double tail and missing tail.

When the sum of all kinds of abnormal sperm does not exceed 20% of the total sperm, it can be regarded as a normal phenomenon.

However, when there are too many immature sperm, aged sperm and abnormal sperm, it will affect normal fertilization and is negatively related to fertility. The fertility of adult males is directly proportional to the number and vitality of sperm, and inversely proportional to the abnormal sperm rate.

The higher the sperm abnormality rate, the more difficult it is to get pregnant.
