We all know that only normal and healthy sperm can combine with an egg to form an embryo and develop into a fetus. In real life, many men experience infertility symptoms, most of which are related to sperm problems. By examining semen, it is possible to determine if the sperm are normal. So what is the normal form of sperm?
What is the normal morphology of sperm
Normal sperm resemble tadpoles and consist of three parts: head, body, and tail. The head is slightly flattened, oval in shape, with a regular contour and a clear acrosome. The acrosome cap covers more than 1/3 of the surface of the head and presents a translucent area at the front end of the sperm head. The head length is 3-5um, the width is 2-3um, and the aspect ratio is 1.5-2:1. The aspect ratio is one of the important data to determine whether the sperm morphology is normal.
The middle section of the body is slender, with a width of less than 1/3 of the head, and the contour is straight and regular, forming a straight line with the longitudinal axis of the head. It is about 5-7um long and lum wide. The tail is slender, with a regular appearance without curling, generally 50-60um long. The HE stained acrosome appears light red, with the nucleus located at the base of the acrosome, appearing purple red, and the tail appearing light purple red. Improved Pap staining results in a pale green acrosome, a purple red nucleus, and a green tail.
What is the abnormal morphology of sperm
There are many types of abnormal sperm morphology, with over 70 variations.
1. Head abnormalities: Common types include large head, small head, conical head, amorphous head, bubble like head, double head, decapitated head, etc.
2. Body abnormalities: Common symptoms include swelling, irregularity, bent midsection, and abnormally thin midsection.
3. Tail abnormality: Common types include no tail, short tail, long tail, double tail, curled tail, etc.
4. Joint defect body: The head, body, and tail of the sperm are all or both of them have varying degrees of abnormalities.
The above has shared with you what normal sperm form is, and after reading it, you should also have some understanding. At the same time, the editor will also share with you the morphology of abnormal sperm. Abnormal sperm can cause infertility, and it is necessary to go to the hospital for examination and treatment in a timely manner. Early examination can lead to early treatment and recovery of health.
