Deciding to have a baby can be one of the most exciting and wonderful times in life. But it’s also a time when many parents-to-be worry about the health of their child.
Pre-implantation genetic diagnosis (PGD) can provide peace of mind by reducing the risk of passing on genetic disorders to your child. Here’s what you need to know about PGD.
What is pre-implantation genetic diagnosis?
Pre-implantation genetic diagnosis is a technique that can help you have a healthy baby if you are at risk of having a child with a genetic disorder.
It involves testing an embryo for specific genetic mutations or chromosomal abnormalities before it is transferred to the uterus.
PGD is often used for couples who have a known history of genetic disorders, such as cystic fibrosis, sickle cell anemia, spinal muscular atrophy, or Huntington’s disease.
It can also be used for couples who are carriers of a genetic disorder, meaning they have a higher risk of having a child with the condition.
How is pre-implantation genetic diagnosis done?
PGD is done during in vitro fertilization (IVF), which involves fertilizing eggs with sperm in a laboratory and then implanting the resulting embryos into the uterus.
After the eggs are collected, they are fertilized in the lab, and allowed to develop into embryos. At day 3 or day 5 of development, a few cells are removed from each embryo for genetic testing. The embryos that do not carry the genetic mutation or chromosomal abnormality are selected for transfer to the uterus.
What are the benefits of pre-implantation genetic diagnosis?
Pre-implantation genetic diagnosis has several benefits for couples who are at risk of having a child with a genetic disorder:.
- Reduced risk of passing on genetic disorders to their children
- Option to select embryos based on gender or other traits
- Increased chances of a successful pregnancy for couples who have had unsuccessful IVF cycles
PGD can also help couples avoid the difficult decision of whether to terminate a pregnancy if genetic testing reveals a serious genetic disorder.
What are the risks of pre-implantation genetic diagnosis?
Like any medical procedure, pre-implantation genetic diagnosis does have some risks, although they are generally low. Possible risks include:.
- Damage to the embryo during genetic testing
- False-positive or false-negative results
- Multiple gestation (carrying more than one fetus), which can increase the risk of complications during pregnancy and birth
Your doctor will discuss the risks and benefits of PGD with you and help you decide whether it is the right choice for your family.
How much does pre-implantation genetic diagnosis cost?
Pre-implantation genetic diagnosis is an expensive procedure, and it is not covered by most insurance plans. The cost can vary depending on the clinic and the number of embryos tested. On average, PGD costs between $3,000 and $7,000.
However, some clinics may charge up to $20,000 or more for the procedure.
Is pre-implantation genetic diagnosis right for you?
If you are at risk of having a child with a genetic disorder, pre-implantation genetic diagnosis may be a good option for you. However, it is important to discuss your options with a doctor or genetic counselor before making a decision.
Your doctor or counselor can help you understand the risks and benefits of PGD, as well as alternative options, such as adoption or using donor eggs or sperm.
The bottom line
Deciding to have a baby is a big decision, and it’s natural to worry about the health of your child. Pre-implantation genetic diagnosis can provide peace of mind by reducing the risk of passing on genetic disorders to your child.
If you are considering PGD, talk to your doctor or genetic counselor to learn more about your options.
