FISH Sperm Analysis London
FISH Sperm Analysis is a specialised genetic test that examines chromosomes inside sperm cells to identify abnormalities that may affect fertilisation, embryo development, and pregnancy outcomes.
At Marylebone Diagnostic Centre, private FISH sperm testing supports men with infertility, recurrent miscarriage, abnormal semen findings, or failed IVF and ICSI cycles.
What Is FISH Sperm Analysis?
FISH sperm testing uses fluorescent probes to detect abnormalities in specific chromosomes within sperm cells, helping uncover issues that standard fertility testing may miss.
This test can identify:
- Extra chromosomes
- Missing chromosomes
- Structural abnormalities
What Does This Test Analyse?
FISH testing commonly evaluates chromosomes such as:
- Chromosome 13
- Chromosome 18
- Chromosome 21
- X and Y chromosomes
These are linked to conditions such as Down syndrome and other chromosomal disorders.
Who Should Take This Test?
- Male infertility
- Recurrent miscarriage
- Failed IVF or ICSI cycles
- Abnormal semen analysis
- Known chromosomal abnormalities
Often combined with DNA Fragmentation and Karyotype testing.
How the Test Works
- Step 1: Semen sample collection
- Step 2: Sperm cells are prepared and fixed
- Step 3: Fluorescent probes are applied to specific chromosomes
- Step 4: Microscopic analysis identifies abnormalities
- Step 5: Detailed report with findings
What Do the Results Mean?
- Normal result: Low levels of chromosomal abnormalities and a better fertility outlook
- Abnormal result: Increased chromosomal abnormalities that may affect fertilisation and embryo health
- Results help guide fertility treatment decisions and IVF strategy
