Sperm FISH analysis

An analysis of the chromosome number of spermatozoa is performed using FISH (Fluorescent In Situ Hybridisation) analysis. This technique provides valuable information on the quality of the sperm’s genetic material, which would not be possible with conventional semen analysis. The occurrence of increased sperm rates with an increased number of chromosomes or with an increased rate of fragments in the DNA may indicate infertility and a possible cause of failed IVF.


• Embryolab is one of the few IVF units in the world to have a Department of Genetic Counselling within the unit.
• The FISH test is performed at the Unit by specialised cytogeneticists.
• Since 2013, Embryolab Academy has organised international seminars, bringing together scientists from around the world for training in the application of these methods.
