Sperm morphology in the clinical generally refers to sperm morphology, sperm morphology measurement in the clinical commonly used staining analysis, most of the modified Pasteur staining method, or HE staining, Rachel’s staining method and other methods. Sperm morphology measurement is commonly used in clinical staining analysis, staining methods include: modified Pap staining, HE staining, Rachel’s staining method, and so on. Normal spermatozoa are those with normal head, neck, mid-section, and tail during sperm morphometry. The head of the spermatozoon is oval with well defined acrosome. The midpiece is thinner than the head and is about 1.5 times longer than the head. The tail should be straighter and thinner than the midpiece and homogeneous. The total length of the spermatozoa is about 50⁓60 μm and the external shape resembles that of a tadpole. When checking the normal morphology of spermatozoa, according to strict standards, the proportion of normal morphology of spermatozoa should account for 3% ⁓ 4% in the semen of normal fertile men. Patients should go to regular hospitals for testing.
