Sometimes it is not possible to detect the exact genetic error that causes the disease, but PGD can be used to identify the gender so only embryos of the unaffected gender and with the correct number of chromosomes will be transferred.

Gender selection is prohibited for anything other than medical reasons. A gene is a sequence of genetic material DNA with a particular function on a chromosome. Humans have up to 20, different genes, arranged on 23 pairs of chromosomes. When the DNA sequence on a particular gene is altered, a genetic disorder, such as cystic fibrosis, may result. To identify which embryos are unaffected by the single gene defect that is present in a family, a patient-specific test is developed by the PGD team.

As these tests are couple-specific, they can take some time and effort to design and establish. If you have a parent who has been affected by a serious genetic condition such as Huntingtons disease later in life you may wonder whether this is a condition you can pass on to your children. Many people do not want to have testing to determine if they have inherited that condition from their parent, but at the same time do not want to risk passing it on to their own children. In this situation PGD can be used to perform exclusion testing.

These samples will be used to develop the probe. This process typically takes a number of weeks. Step 3: Egg Collection Next, a doctor will perform the egg retrieval. After egg retrieval, an embryologist will assess the eggs. Step 4: Fertilization Next, a doctor will fertilize each egg in the laboratory. This is done either with conventional fertilization, where the eggs and sperm are put together in a culture dish or through intracytoplasmic sperm injection ICSI.

ICSI is a procedure where specialist injects a single sperm cell into each egg cell. Step 5: Culture and Biopsy Eggs that fertilize are then kept in the laboratory for five to six days until they reach blastocyst stage. A blastocyst embryo typically contains about cells.
