Definition of sperm morphology

Sperm morphology examination is to understand the proportion of normal sperm and mutant sperm in the physiological and pathological range, and is an important indicator of male fertility.

The fertility of the sperm is closely related to the normal shape and structure of the sperm. The more sperm with normal shape and structure, the greater the chance of conception, indicating a better fertility. Some scholars made 190 times to 129 people

The main means of sperm morphology

Sperm smear staining is the main method to analyze sperm morphology. Normal sperm and mutant sperm in the physiological and pathological range can only be analyzed by staining.

commonly used ways

The commonly used method is smear method, when

The quality of sperm directly affects the big problem of fertility, so doctors often use sperm quality inspection to judge male fertility. For sperm quality checks often include

1. Head defects: big head, small head, conical head, pear-shaped head, round head, amorphous head, hollow head, acrosome too small (less than 40% of the head), double head, and the above defects Any combination. May be related to genetic factors and exposure to high temperature, radiation, chemicals, biotoxins and other factors. The worse the sperm DNA integrity.

2. Defects of the neck and middle section: The neck is "bent" (the angle between the neck and the tail is greater than 90% of the head and axis), and the middle section is asymmetrically connected to the head, thick or irregular middle section (mostly Residual bodies during sperm maturation may be abnormally combined with sperm cells becoming sperm), abnormally thin mid-sections (ie, mitochondrial sheaths), and any combination of the above defects. May be related to the energy metabolism of sperm. Because sperm energy metabolism is related to mitochondria.

3. Tail defects: short tail, multiple tails, hairpin tails, tail breaks, tail bends (> 90 degrees), irregular tail widths, tail bends, or any combination of the above defects. May be related to the transport of sperm nutrients, reproductive tract infections and sperm motility.

4. Cytoplasmic droplets are larger than half of the normal sperm head. This droplet is usually in the middle. ^[3]
