Within the diagnosis of male infertility factors, an important parameter, among others, is determining the proportion of immature sperm in the semen. Immature sperm have a reduced ability to repair DNA and a lower probability of fertilizing an egg.
The probability of producing a viable embryo is thus significantly reduced. The principle of the examination is to determine how the dye (aniline blue) binds to the chromatin in the sperm nucleus. If the sperm is mature and physiologically developed, its head will be lightly stained, whereas the head of a sperm with a maturation delay will be strongly stained. A proportion of immature sperm in the semen exceeding 26% is considered above the threshold (i.e., pathological).
Evaluation of sperm functional tests allows us to suggest the most suitable methods of processing and selecting sperm for egg fertilization, thereby increasing the success rate of your treatment.
