What Is IVF and Why Might It Lead to Twins?
IVF, or IVF full form, i.e., in-vitro fertilisation, is a medical procedure where doctors fertilise an egg with sperm outside your body to create embryos. After being fertilised, one or more embryos may be placed in the uterus for implantation, which would result in pregnancy. The fertility specialists optimise the process to increase the possibility of conception, but the occurrence of pregnancy depends on many factors, including the number of transfers.
In the early days of IVF, doctors often transferred multiple embryos to increase the chances of pregnancy. However, this also leads to the high possibility of having twins or triplets. However, with advancing technology and increasing success rates, doctors often advise transferring only a single embryo, especially for women under 35.
IVF: Myths and Facts
Let’s clarify some of the most common IVF myths for you.
Myth 1: IVF Always Results in Twins
This is one of the most common myths. IVF treatment does not inevitably mean twin pregnancy. IVF, indeed, has a slightly higher chance of multiple births. However, this is far from guaranteed. Single Embryo Transfer (SET) is the current trend in fertility treatments. It minimises the risk of twins and other multiples.
For example, single embryo transfer has become a preferred method across India, especially for women under the age of 35. This drops the probability of twins significantly. It can align closer to natural conception rates.
Myth 2: Twins Born Through IVF Are Weaker or Face More Health Risks
This is another common misconception. IVF twins do not necessarily face excessive health risks. However, multiple pregnancies can add to them. And this does not apply just to IVF but to natural conception, too. A lower birth rate or preterm birth might be a possibility if you are carrying twins and other multiples. However, this is because of multiples, not the IVF procedure itself.
Myth 3: IVF Increases Your Odds of Identical Twins
Are you one of those who believe that IVF treatment directly increases your chance of having identical twins? Well, this isn’t entirely accurate. When a single fertilised embryo splits into two, it results in identical twins. This can happen randomly. It might be a fact that the IVF environment slightly increases your probability.
Fact: IVF Procedures Can Be Tailored to Your Preferences
IVF is exceptionally flexible. What we mean by this is that you can openly discuss your preferences and risks with your fertility doctor. Do you want twins? Do you want a single pregnancy? No matter what, your doctor can adjust the number of embryos depending on your choice. This embryo transfer is also based on your health, age, and fertility history.
Fact: The Twin Rate in IVF Has Declined Over Time
IVF techniques have advanced significantly. Nowadays, clinics are more focused on single embryo transfers. Hence, the rate of twin pregnancies is getting reduced. The medical world is experiencing a steady decline in twin births. It is particularly true for younger females because their percentage of SETs is higher. This shift promotes a safer pregnancy journey. It also aligns with international standards in fertility care.
For instance, in India, the rate of twin births through IVF has decreased over the past decade as clinics prioritise single embryo transfers. Patients over 35 or those with previous unsuccessful IVF cycles may still consider multiple embryo transfers. However, the overall trend leans toward healthier, single pregnancies.
Conclusion
The idea of twins through IVF can be appealing. However, it is important to separate the myths from reality. Thanks to advancements in reproductive medicine and a focus on single embryo transfers, the likelihood of twin births via IVF has declined. The procedure now offers a highly personalised and safe approach. You can achieve your parenthood dreams with health and safety.
