Common tests for male infertility

Semen analysis typically includes sperm density, motility, motility percentage, and sperm morphology indicators, which reflect male fertility to some extent. Sperm morphology staining analysis is an important indicator of sperm quality. The WHO stipulates that if the proportion of normally shaped sperm is less than 15%, it is classified as teratospermia. If the percentage of abnormal sperm in the semen exceeds 80%, genetic factors should be considered, especially defects in genes on the Y chromosome. The immotile sperm observed during routine semen analysis with eosin staining are not necessarily dead sperm; live staining can be used to distinguish them, as live sperm do not take up the stain. Sperm hypo-osmotic swelling test.

Semen routine analysis includes sperm density, motility, motility percentage, and sperm morphology indicators, which reflect male fertility to some extent.

Sperm morphology staining analysis is an important indicator of sperm quality. The WHO stipulates that if the proportion of normally shaped sperm is less than 15%, it is considered teratospermia. If the proportion of abnormal sperm exceeds 80%, genetic factors should be considered, especially defects in genes on the Y chromosome.

The immotile sperm observed in the routine analysis of semen with eosin staining is not necessarily dead sperm; live staining can be used to distinguish, as live sperm do not take up the stain.

The hypo-osmotic swelling test serves as an indicator of sperm membrane function and integrity, assessing sperm viability and predicting potential fertilization ability.

Mixed antiglobulin reaction test for initial screening of antisperm antibodies.

The post-coital test assesses sperm motility and survival time in cervical mucus, which is influenced by many factors. In standard tests, having more than 10 forward motile sperm per high power field in the cervical os and cervical canal mucus indicates normal results.

The sperm-cervical mucus capillary penetration test is used to identify whether the factors causing abnormalities in the post-coital test are related to the male or female partner.

Fructose qualitative test: Fructose is a marker of seminal vesicle function. If fructose in the seminal plasma is zero, combined with sperm cell examination and hormone tests, it can differentiate between obstructive azoospermia and functional azoospermia.
