Identify hidden genetic causes of male infertility with advanced Y chromosome testing. Private, discreet analysis in Central London.
Y Chromosome Microdeletion Test London
Male infertility is often overlooked, yet in many cases, the cause lies in genetics.
At Marylebone Diagnostic Centre, we offer private Y chromosome microdeletion testing in London to help identify the root cause of infertility and support informed treatment decisions.
What Is a Y Chromosome Microdeletion?
The Y chromosome contains genes essential for sperm production. A microdeletion is a missing segment of DNA that can disrupt sperm development and may lead to low sperm count or azoospermia.
Why this matters in male fertility:
- Microdeletions are a common genetic cause of male infertility
- Findings can directly influence IVF or ICSI planning
- Diagnosis can prevent unnecessary fertility treatments
- Results provide clearer long-term family planning options
Who Should Take This Test?
This test is recommended for:
- Low sperm count (oligospermia)
- No sperm in semen (azoospermia)
- Failed fertility treatments
- Unexplained male infertility
- Couples planning IVF or ICSI
Types of Y Chromosome Deletions
Common regions affected include:
- AZFa deletion: Severe sperm production issues
- AZFb deletion: Arrested sperm development
- AZFc deletion: Reduced sperm count (most common)
How the Test Works
- Step 1: Blood sample collection
- Step 2: DNA analysis for Y chromosome deletions
- Step 3: Report confirming presence and type of deletion
- Step 4: Optional consultation on fertility options
What Do the Results Mean?
Your findings can guide the next best fertility pathway:
- No deletion detected: Other infertility causes may be investigated
- Deletion detected: Genetic cause identified and treatment plans refined
- Results support decisions around natural conception, IVF, and ICSI
