Y-Chromosome Microdeletion Analysis near me in Kolkata









The Y-Chromosome Microdeletion Analysis test is a specialized genetic analysis designed to detect the absence of small regions on the Y chromosome. It focuses on identifying deletions in three main regions: AZFa, AZFb, and AZFc, each associated with different patterns of impaired sperm production. In most cases, AZFa deletions are linked to the absence of sperm. AZFb deletions often disrupt normal sperm development, while AZFc deletions may still allow sperm retrieval in some individuals. Results are interpreted by a doctor in the context of clinical findings and fertility evaluation. This test is widely available with Tata 1mg labs at an affordable price in Kolkata.








What does Y-Chromosome Microdeletion Analysis measure?
The Y-Chromosome Microdeletion Analysis test detects microdeletions, which are microscopic missing DNA segments in the Y chromosome, and identifies the specific region affected. By mapping the deletion, the test provides important details about how it might influence sperm production and may affect fertility potential. This information helps doctors plan suitable treatment options, evaluate the chances of retrieving viable sperm, and understand the likelihood of passing the genetic change to future male children.
