Dr. Ladu Dewasi is a Consultant Gynaecologist and Infertility Specialist practising at Mayflower Women’s Hospital, Bopal-Ambli, Ahmedabad. Genetic testing here is considered as part of your overall fertility or pregnancy plan, so the test is selected according to your history, family history, age, and reproductive needs, rather than ordered as a routine add-on. He also holds an MD in Anaesthesia, which is directly relevant when PGT requires an embryo biopsy carried out during an IVF cycle: sedation and pain management for that cycle are planned and managed by the same doctor throughout, rather than handed off to someone meeting you for the first time.
Genetic testing uses a blood, saliva, or other appropriate sample to look for specific changes in genes or chromosomes. In IVF, embryo testing may involve a small biopsy of cells from the embryo’s outer layer at the blastocyst stage.
Genetic testing may come up at a few specific points in a fertility or pregnancy journey:
If you’re not sure whether any of this applies to you, that’s a reasonable thing to bring to a consultation rather than work out on your own.


PGT is performed on embryos created through IVF. A trained embryologist takes a small number of cells from the embryo’s outer layer, usually at the blastocyst stage (around day 5 to 6 of development), and the embryo is generally frozen while testing is completed. This biopsy is a standard, established laboratory step and is not expected to prevent a genetically suitable embryo from continuing to develop normally after transfer.
Karyotyping examines the chromosomes in a blood sample and may be considered in selected cases of recurrent pregnancy loss or infertility. When sperm counts are very low or absent, additional genetic testing such as Y-chromosome microdeletion analysis may be recommended as part of a broader infertility assessment.
Genetic testing may be worth discussing if:
Not everyone needs genetic testing. Just as often, the useful outcome of a consultation is understanding that testing isn’t necessary for your situation right now, and that’s a legitimate answer, not a missed opportunity.
For many genetic tests, the process involves a simple blood or saliva sample. The sample is sent to a specialised laboratory, and turnaround time depends on the specific test, typically around one to three weeks for carrier screening and karyotyping.
For PGT, embryo biopsy is performed as part of the IVF laboratory process, and results are usually available within one to two weeks. The embryo is generally frozen while genetic testing is completed, and transfer is planned based on the overall treatment plan and test results.


Genetic results are not always simply positive or negative. A result may need to be interpreted alongside your medical history, family history, and reproductive goals.
Where appropriate, genetic counselling can help you understand what a result means, what it may mean for future pregnancies or family members, and what options are available. This is treated as a standard part of the process, not an optional extra, especially since a result can sometimes have implications for other family members.
