In-vitro fertilization (IVF) is one of the most advanced fertility treatments available to couples facing infertility. Over the years, IVF has brought joy to countless families in Lahore and across Pakistan by making parenthood possible.

Twins in Natural Conception vs. IVF

In natural conception, the chance of having twins is relatively low, usually around 1–2% of pregnancies. Identical twins occur when a single fertilized egg splits into two, while fraternal twins happen when two separate eggs are fertilized during the same cycle.

With IVF, the chances are higher because more than one embryo may be transferred into the uterus to increase the likelihood of pregnancy. This medical approach often leads to multiple pregnancies, including twins or, in rare cases, triplets.

Why Does IVF Increase the Chances of Twins?

IVF involves several steps that can raise the possibility of twins:

1. Multiple Embryo Transfer

   • During IVF, doctors sometimes transfer more than one embryo to increase the chances of implantation and pregnancy.

   • If both embryos implant successfully, this results in twins.

2. Ovarian Stimulation

   • Fertility medications given during IVF stimulate the ovaries to produce multiple eggs.

   • This naturally increases the potential for multiple embryos to develop.

3. Embryo Splitting

   • Even if only one embryo is transferred, it may occasionally split into two, resulting in identical twins.

Chances of Twins with IVF in Lahore

The likelihood of twins with IVF in Lahore depends on several factors, including the number of embryos transferred, the patient’s age, and clinic protocols. On average:

• 20–30% of IVF twin pregnancies occur when two embryos are transferred.

• 1–2% chance of identical twins exists even when a single embryo is transferred.

• Younger women, especially under 35, are more likely to experience successful implantation of multiple embryos, which increases twin chances.

Factors That Influence Twin Pregnancies

Several factors can raise the likelihood of twins in IVF:

1. Age of the Woman

   • Women under 35 have a higher chance of multiple pregnancies since their embryos are more viable.

2. Number of Embryos Transferred

   • The more embryos transferred, the greater the chance of twins. Many fertility centers in Lahore now recommend transferring fewer embryos to reduce risks.

3. Use of Fertility Medications

   • Strong ovarian stimulation can lead to more eggs, creating opportunities for multiple fertilizations.

4. Genetic and Biological Factors

   • A natural family history of twins may slightly increase the chances, though IVF plays the primary role.

Benefits and Joy of Twin Pregnancies

For many couples, the thought of having twins is exciting. After struggling with infertility, the possibility of welcoming two babies at once feels like double the blessing. Benefits include:

• Achieving a larger family in a single pregnancy.

• Emotional fulfillment after years of trying.

• Cost-effectiveness for couples undergoing expensive fertility treatment.

Risks of Twin Pregnancies with IVF

While twin pregnancies can be joyful, they are also considered high-risk compared to single pregnancies. Couples in Lahore should be aware of the potential challenges:

1. Preterm Birth

   • Twins are often born earlier, sometimes requiring neonatal intensive care.

2. Low Birth Weight

   • Babies may have lower weight and need medical support initially.

3. Gestational Diabetes and High Blood Pressure

   • Mothers are at higher risk of pregnancy complications.

4. Cesarean Delivery

   • The chance of needing a C-section is significantly higher with twins.

Because of these risks, fertility specialists often recommend single embryo transfer (SET) when medically suitable, to promote safer pregnancies while still maintaining good success rates.

IVF Practices in Lahore Regarding Multiple Pregnancies

Modern fertility centers in Lahore follow international guidelines to balance patient safety and pregnancy success. Current practices include:

• Transferring one or two embryos depending on the patient’s age and medical history.

• Providing counseling about twin risks and benefits before embryo transfer.

• Monitoring twin pregnancies more closely through regular ultrasounds and checkups.

• Using advanced lab techniques to select the best-quality embryo, reducing the need for multiple transfers.

How Can Couples Decide?

Couples considering IVF in Lahore should discuss the following with their infertility specialist:

• The chances of pregnancy with one vs. two embryos.

• The medical risks associated with carrying twins.

• The couple’s personal and financial readiness for raising multiples.

Making an informed decision ensures the process is safer for both mother and babies.

Conclusion

The chances of twins with the IVF procedure in Lahore are higher than natural conception, primarily due to multiple embryo transfers. On average, the likelihood of having twins ranges between 20–30% when two embryos are transferred. While this brings excitement for many couples, it also comes with medical risks that must be carefully considered.

Modern IVF practices in Lahore focus on patient safety, offering individualized care and advanced techniques to balance success rates with healthy outcomes. For couples dreaming of parenthood, understanding the chances of twins and the associated risks helps in making well-informed decisions on their IVF journey.
