Gender selection is one of the most talked-about and misunderstood topics in fertility treatment. Advances in IVF now allow doctors to see extensive genetic details about embryos, which often leads couples to wonder: can you really know—and choose—a baby's gender?
The short answer is yes, genetic testing can identify sex chromosomes. But that's not the same as choosing a baby's sex. And in India, that distinction is important. Knowing the true purpose and limitations of IVF and genetic testing can help dispel many common myths and misunderstandings about gender selection.
Quick Answer
● IVF combined with PGT can identify whether an embryo has XX or XY chromosomes.
● In India, it is against the law to choose the sex of a baby for reasons that are not medical.
● PGT is primarily used to detect chromosomal abnormalities and inherited genetic disorders.
● Fertility specialists focus on selecting healthy embryos rather than choosing a baby's gender.
Can IVF Determine Baby's Gender?
Yes. When people use genetic testing with In-vitro Fertilization or IVF, they can figure out if an embryo has XX or XY sex chromosomes. So, IVF can really determine the gender of a baby before the embryo is transferred.
However, this is where many misconceptions arise. Identifying the sex chromosomes of an embryo is not the same as selecting a baby's sex. The primary purpose of embryo testing is to look for chromosomal abnormalities or inherited conditions that could affect the chances of pregnancy or the health of the baby.
In other words, the technology can reveal this information. That doesn't mean the information can be used freely for gender selection. And that distinction matters because the rules around this vary from country to country.
Myth vs Fact
Myth: People often think IVF helps parents decide if they want a boy or girl.
Fact: IVF is primarily for helping people achieve pregnancy. Genetic testing in IVF may reveal an embryo's sex chromosomes. Sex selection, for non-medical reasons, is not permitted in India.
So, What Exactly is PGT?
If IVF can reveal an embryo's sex chromosomes, how does that happen? The answer lies in a specialised test called Preimplantation Genetic Testing (PGT), which is performed on embryos created through IVF before they are transferred into the uterus. Its purpose isn't to "pick" boys or girls. Instead, it helps identify embryos with certain chromosomal abnormalities or inherited genetic disorders.
Doctors may recommend genetic testing in situations such as:
● Recurrent miscarriages
● Multiple unsuccessful IVF cycles
● Advanced maternal age
● A known family history of genetic disorders
● Risk of inherited conditions linked to sex chromosomes
This is why you'll sometimes come across terms such as PGT for gender selection online. PGT is a tool that helps select the best embryos and reduces the risk of passing on certain genetic conditions. Choosing a baby's gender is a separate issue altogether.
How is PGT performed?
During PGT, specialists gently remove a small number of cells from the embryo in a controlled laboratory setting. These cells are analysed to assess chromosomal health or identify specific genetic conditions before the embryo is transferred to the uterus.
Gender Selection in IVF Treatment: What Does Indian Law Say?
For couples seeking fertility treatment in India, the answer is clear. Gender selection in IVF treatment for non-medical reasons is prohibited. In India, the Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act prohibits sex selection before or after conception. This means fertility clinics cannot perform IVF gender selection, only for parents to choose whether they want a boy or a girl.
However, genetic testing may still be recommended for medical reasons. For example, if a family carries a serious genetic disorder that primarily affects one sex, doctors may use genetic testing as part of preventing the transmission of that condition. So while genetic testing and IVF are legal and widely practised, sex selection for family balancing or personal preference is not permitted in India.
When is Genetic Testing Actually Helpful?
Most couples considering IVF will never need genetic testing. But for some families, it can provide valuable information.
Doctors may discuss genetic testing when:
Recurrent Pregnancy Loss is a Concern
Repeated miscarriages can sometimes be linked to chromosomal abnormalities. Testing embryos may help identify embryos more likely to result in a healthy pregnancy.
Maternal Age is Advanced
As women get older, the chances of chromosomal abnormalities increase. Genetic testing may be considered in selected cases.
There is a Family History of Genetic Disorders
Certain inherited conditions can be passed from one generation to the next. Testing may help reduce that risk.
There is a Risk of Sex-Linked Disorders
Conditions such as Duchenne muscular dystrophy or haemophilia are examples where genetic testing may play an important role in preventing transmission to future children. And that's really what PGT is about: reducing genetic risk rather than choosing a baby's sex.
Not necessarily. A healthy embryo matters far more than whether it's male or female.
Pregnancy success depends on many factors. This includes the woman's age, the embryo's health, how well her uterus is functioning, and her reproductive health. People think that choosing a baby boy or girl might make the pregnancy more likely to work out. But there is no proof that this really makes a difference. Choosing an embryo just because it is a boy or a girl does not really improve the chances of having a pregnancy. Pregnancy success and embryo quality are important factors to consider when trying to have a baby.
In reality, most couples undergoing IVF are not trying to choose a baby's sex. They're trying to maximise the chances of having a healthy baby. These are two entirely different goals.
Looking Beyond Gender
Questions about gender selection are understandable. After all, advances in IVF and genetic testing have made fertility treatment more sophisticated than ever before. For most couples, the real goal is much broader than simply choosing a boy or a girl. Their primary focus is on creating healthy embryos, achieving a successful pregnancy, and ultimately welcoming a healthy baby into their family. Genetic testing can be a valuable tool in selected situations, especially when there's a risk of inherited disorders. But its role is medical, not social. Understanding that difference helps set realistic expectations and keeps the focus where it belongs - on giving every pregnancy the best possible start.
If you're considering IVF and have questions about genetic testing, a fertility specialist can help you understand whether PGT is appropriate for your individual situation and explain the benefits, limitations and legal considerations involved.

Yes. In fact, that's how PGT is commonly used. Genetic testing is primarily performed to assess chromosomal abnormalities or inherited disorders, and not for selecting the sex of the baby.
Does gender selection improve the chances of a healthy pregnancy?
No. Pregnancy success depends largely on embryo quality, maternal age, and several other factors. Selecting an embryo based solely on sex does not improve pregnancy outcomes.
How much does IVF with genetic testing cost?
In India, IVF with PGT may add approximately ₹1.5 lakh to ₹3 lakh or more to the overall treatment cost. The cost of IVF with PGT varies based on the type of testing, the number of embryos analysed, and the treatment plan recommended by your fertility specialist. Costs can vary significantly between centres and should be discussed during consultation.
Can gender-linked genetic disorders be prevented through IVF?
Yes, in selected cases. Couples with a known risk of sex-linked genetic disorders may benefit from IVF with genetic testing to reduce the chances of passing these conditions to their children. Your fertility specialist and genetic counsellor can advise whether this approach is appropriate for your situation.
