Tunel test
The Tunel test is a laboratory technique used to detect DNA fragmentation in sperm cells.
This test is an indicator of the integrity of sperm DNA, a condition necessary for male fertility, and involves the analysis of single-stranded DNA. The results of the Tunel test indicate the percentage of DNA fragmentation in sperm cells.
A high percentage of DNA fragmentation can be associated with reduced fertility, a greater likelihood of assisted reproduction failures, and an increased risk of miscarriages.
The Fish and Tunel tests on semen provide crucial information about sperm quality and male reproductive health.
These tests are particularly useful for couples facing infertility issues and can guide clinical decisions regarding assisted reproduction treatments.

Who it's recommended for
The Tunel test is indicated in the following cases:
Unexplained male infertility
History of reproductive failures
Screening of sperm quality before assisted reproduction treatment
TUNEL TEST
Analysis method
The patient provides a semen sample through masturbation, collected in a sterile container.
Sperm cells are isolated from the semen and prepared for analysis.
Sperm cells are treated with a solution that labels the ends of fragmented DNA with a fluorescent marker.
The sample is examined under a fluorescence microscope to detect and quantify the percentage of sperm cells with fragmented DNA.
