Y-Chromosome Microdeletion Analysis near me in Hyderabad

The Y chromosome is one of the two sex chromosomes in males (XY) and carries genes that are important for male reproductive development and sperm production. Normally, a healthy male has a complete Y chromosome. However, small missing sections of DNA, called microdeletions, in certain areas of the Y chromosome, especially the AZF (Azoospermia Factor) regions can affect sperm production and may lead to male infertility.

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 recommended for men with unexplained infertility, especially those with non-obstructive azoospermia or severe oligozoospermia. It is also advised before fertility treatments like testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI). The test may help doctors estimate the chances of retrieving sperm and assess the risk of passing the genetic condition to male children if conception occurs using the patient’s sperm, including through ICSI.

Since microdeletions in the Y chromosome are inherited, this test can also provide valuable insights for genetic counseling. Understanding the presence and type of microdeletion enables doctors to guide patients in making informed reproductive decisions, including the choice of donor sperm if needed.

For the Y-Chromosome Microdeletion Analysis, a filled Chromosome & FISH Analysis Requisition form (Annexure - CR/03) is mandatory. This form must be completed prior to the sample collection, and it helps ensure that all necessary patient information is provided for accurate testing and analysis.

Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation. Therefore, do not make treatment decisions on your own, based solely on these results, and always consult a doctor for a proper understanding of the test results. 

Please note: This is an outsourced test. The sample for this test is collected by TATA 1MG and processed at a NABL accredited partnered lab.
