Sperm chromosome study (FISH)
When a chromosomal study of sperm with FISH is pathological, what treatment options are there?
When a FISH mediate chromosomal study is pathological, that is when the presence of an alteration in the number of chromosomes in the spermatozoa is detected, the treatment options may vary depending on the clinical history of the patients:
- To carry out a pre-implantation genetic diagnosis (PGD) to check that the embryo does not present alterations and to carry out the embryo transfer with those that have a greater probability of implanting and evolving, given that genetically they are normal.
- Prenatal diagnosis in case of gestation.
- Resorting to treatment with donor sperm in cases of very serious alterations.
