Twin Pregnancies and IVF
Twin pregnancies are more common in in vitro fertilization (IVF) compared to natural conception. While the chance of having twins in a typical pregnancy is about 6%, this likelihood can increase to approximately 25% with IVF. At Lotus IVF, transferring multiple embryos increases the likelihood of a successful pregnancy. If only one embryo is transferred, the chance of twins is minimal, but any twins in this case would likely be identical, resulting from splitting the single embryo.

Factors influencing the likelihood of twins in IVF include:

• Age and Health: The age and overall health of the woman can impact the success and outcome of IVF.
• Embryo Quality: The quality of the embryos transferred affects the likelihood of a multiple pregnancy.
• Fertility Clinic Practices: Different clinics have varying protocols for the number of embryos transferred, which can influence the incidence of twin pregnancies.

Here are some potential drawbacks of twin pregnancies in IVF:

• Increased Risk of Complications: Twin pregnancies have a higher likelihood of complications such as preterm labor, and gestational diabetes.
• Higher Chances of Preterm Birth: Twins are often born prematurely, which can lead to health issues for the babies, such as respiratory problems and a need for NICU care.
• Low Birth Weight: Twins are more likely to be born with low birth weight, increasing the risk of developmental delays and other health concerns.
• Strain on Maternal Health: Carrying twins can be more physically demanding, increasing the risk of maternal health issues like high blood pressure, anemia, and the need for a cesarean section.
• Longer Recovery Time: The mother may face a longer and more challenging postpartum recovery period due to the increased strain of carrying and delivering twins.
• Increased Financial Costs: Twin pregnancies and births can lead to higher medical expenses, including potential NICU stays and additional healthcare needs for both mother and babies.

Ovulation for Twin Pregnancy:

• Double Ovulation: If a woman's body releases two eggs during a single menstrual cycle, both eggs can be fertilized by different sperm, leading to zygotic (non-identical) twins. These twins may have different genes and can be of other genders.
• Single Egg Splitting: If one egg is released and splits into two embryos, monozygotic (identical) twins can occur. These twins will have the same genes and be of the same gender.
• Natural and Medical Factors: Some women have a higher likelihood of double ovulation due to genetic reasons or hormonal treatments, increasing the chances of having twin

How to Track Ovulation:

• Ovulation Calculator: Useful for identifying fertile days based on the menstrual cycle.
• Basal Body Temperature: Slightly increases during ovulation, which can be tracked to identify the fertile period.
• Ovulation Kits: These test hormone levels to determine the exact timing of ovulation.

IVF twin pregnancies can present unique challenges and difficulties compared to singleton pregnancies. Here’s an overview of some key factors:

1. Increased Risk of Complications:

• Preterm Labor: Twin pregnancies are more likely to result in preterm labor, leading to early birth and potential health issues for the babies.
• Pre-eclampsia: Higher risk of developing pre-eclampsia, a pregnancy complication characterized by high blood pressure and potential damage to organs.

2. Health Risks for Babies:

• Low Birth Weight: Twins are often born with lower birth weight, which can lead to health problems and an increased need for neonatal care.
• Respiratory Issues: Premature twins may experience respiratory problems and require time in the Neonatal Intensive Care Unit (NICU).

3. Maternal Health Concerns:

• Physical Strain: Carrying twins can be physically demanding, increasing the risk of conditions like gestational diabetes and anemia.
• Cesarean Section: The likelihood of needing a cesarean section is higher with twin pregnancies.

4. Increased Monitoring and Medical Visits:

• Frequent Check-Ups: Twin pregnancies often require more frequent medical visits and monitoring to manage potential complications.

Conclusion:
While IVF twin pregnancies can be more complex and involve additional risks compared to singleton pregnancies, they are not necessarily insurmountable. With careful monitoring, medical support, and proper prenatal care, many families successfully navigate the challenges and experience positive outcomes. Dr. Shruti Ghate emphasizes the importance of consulting with healthcare professionals throughout pregnancy. Regular check-ups and professional guidance are essential for managing risks and ensuring the health and well-being of both the mother and the babies.
