Spermatozoa FISH Clinic
FISH in spermatozoa (Fluorescence in Situ Hybridization) is a technique that allows the genetic material of spermatozoa to be studied. It consists of attaching fluorescent probes to each sperm chromosome in order to determine the number of copies in each sperm in the ejaculate.
Human eggs and sperm have 23 chromosomes and must have one copy of each to be chromosomally normal.
Sperm with chromosomal abnormalities exist in nature, but if the FISH study on sperm indicates that they have a high number of chromosomal alterations, the probability of giving chromosomally altered embryos increases.
These embryos may give rise to recurrent miscarriages or implantation failures.
Depending on the result of the FISH in spermatozoa, our medical and laboratory team will advise you on the most appropriate treatment in your case.
WHEN IS FISH IN SPERMATOZOA INDICATED?
- Men with an abnormal karyotype.
- Patients undergoing chemotherapy or radiotherapy.
- Implantation failures with good quality embryos.
- Repeated miscarriages of unknown cause.
- Previous pregnancy with a chromosomopathy.
