Twins Demand in IVF: Risks vs. Single Embryo Transfer



Twins Demand in IVF: The Clinical Risks vs. Patient Perceptions

During In Vitro Fertilization (IVF) counseling, many couples explicitly request a twin pregnancy. Usually, families view twins as a convenient way to complete their family in a single treatment cycle. This choice seemingly saves time, emotional stress, and financial resources. However, from an advanced medical standpoint, Prof. (Dr.) Abha Majumdar views multiple pregnancies as a critical high-risk complication. The ultimate goal of modern reproductive medicine is always a single, healthy live birth.


Why Do Patients Frequently Request Twins?

Years of primary infertility often drive couples to seek immediate, complete solutions. Consequently, they view a multifetal pregnancy as an ideal outcome. Furthermore, financial pressures lead patients to believe that transferring multiple embryos maximizes their financial investment per cycle.

Unfortunately, significant misconceptions regarding safety persist among families. Many individuals assume that because twins are common, they do not present distinct medical dangers. Therefore, providing structural transparency regarding maternal and fetal complications is vital before starting an IVF cycle.

Professor’s Medical Insight: Satisfying a patient’s demand for twins requires a Multiple Embryo Transfer (MET). While this path raises immediate conception statistics, it exponentially increases dangerous pregnancy pathways. We prioritize long-term maternal and neonatal safety above superficial success rates.


Maternal and Fetal Risks in Twin Pregnancies

When a clinician transfers two or more blastocysts, the maternal body undergoes extreme physiological stress. We monitor these high-risk profiles continuously across two distinct areas:

Risk Category Clinical Complications Long-Term Medical Impact
Maternal Factors Pre-eclampsia, gestational diabetes, and severe gestational hypertension. Elevates life-threatening risks and causes postpartum hemorrhage (PPH).
Fetal Factors Severe preterm birth (PTB) and Intrauterine Growth Restriction (IUGR). Increases the incidence of low birth weight and vital organ immaturity.
Monochorionic Risks Twin-to-Twin Transfusion Syndrome (TTTS) in shared placentas. Demands highly complex fetal interventions to avoid high mortality.

Statistically, over 60% of all twin pregnancies result in premature delivery before 37 weeks. Consequently, these newborns face prolonged admissions to the Neonatal Intensive Care Unit (NICU). These infants frequently battle acute respiratory distress and long-term neurodevelopmental challenges.


Modern IVF Protocols: Elective Single Embryo Transfer (eSET)

To reduce these risks while maintaining exceptional pregnancy success rates, our laboratory at Sir Ganga Ram Hospital enforces strict elective Single Embryo Transfer (eSET) protocols:

  • Extended Blastocyst Culture: We cultivate embryos to Day 5 in specialized, state-of-the-art incubators. This extended phase allows embryologists to identify the single strongest, most viable blastocyst for transfer.
  • Advanced Vitrification (Freezing): If a patient produces multiple high-grade embryos, we transfer only one. Subsequently, we freeze the remaining blastocysts using ultra-rapid vitrification technologies.
  • Subsequent Cycle Mitigation: If the initial fresh transfer does not achieve pregnancy, we utilize the frozen backups sequentially. This method avoids repeating the intensive ovarian stimulation phase entirely.

Patient Counseling and Clinical Consensus

We provide extensive, empathetic counseling to clarify these hidden reproductive realities. When couples evaluate the objective scientific data surrounding neonatal prematurity, they naturally choose safety. Our clinical approach aligns perfectly with international safety standards set by global regulatory bodies.

Ultimately, achieving a smooth, full-term singleton delivery represents the truest victory in reproductive technology. By focusing on single embryo success, we safeguard the health of the mother and ensure a beautiful, healthy future for the child.
