Having Twins: Benefits, Drawbacks, and Risks You Should Know

Clearing Up Questions About Having Twins: A Dream That Can Come True, but Requires Full Understanding

Having twins is a dream for many families. The image of two little ones growing up together, bringing double the laughter and joy, is heartwarming. However, twin pregnancies are unique and involve details that differ from single pregnancies—in terms of chances, benefits, and risks. Parents should study the information thoroughly before making a decision. This article from Siam Fertility Clinic will help you understand every aspect of having twins so your family can plan in the safest and most appropriate way.

Understanding Natural and Medical Twin Pregnancies

Before looking into medical methods for having twins, it’s important to understand the two main types of twins:

Identical Twins

Identical twins occur when one egg is fertilized by one sperm, and the embryo later splits into two. These twins share identical genetics, are always the same sex, and often look remarkably alike. The occurrence of identical twins is entirely natural and cannot be influenced or created through medical technology.

Fraternal Twins

Fraternal twins occur when two eggs are fertilized by two sperm in the same menstrual cycle. This results in two embryos developing in the uterus simultaneously. These twins are genetically different, just like regular siblings. They may be the same sex or different sexes, and they don’t necessarily look alike. Twins conceived through assisted reproductive technologies usually fall into this category.

Benefits of Having Twins That Many Dream Of

• Completing the family at once: For couples facing infertility, having twins can fulfill the dream of a complete family more quickly.

• A strong sibling bond: Twins often grow up very close, acting as playmates and confidants for each other.

• Saving time and long-term costs: Although early expenses may be high, having two children from a single pregnancy can save costs compared to undergoing additional fertility treatments later.

Drawbacks and Risks of Having Twins

Twin pregnancies are considered higher-risk compared to single pregnancies, both for the mother and the babies.

Risks for the Mother

• Preeclampsia: Higher likelihood compared to single pregnancies, leading to high blood pressure and protein in the urine.

• Gestational diabetes: Increased risk in twin pregnancies.

• Preterm birth: One of the most common risks, leading to further complications.

• Higher chance of C-section: Due to fetal positioning or other complications.

  
  

Risks for the Babies

• Low birth weight: Twins often weigh less than average, which can affect long-term health.

• Respiratory issues: Premature birth may result in underdeveloped lungs.

• Other complications: Such as jaundice or feeding difficulties in the early days.

Medical Methods That May Increase Twin Pregnancy Chances

Modern fertility treatments don’t aim to create twins directly—the goal is a healthy pregnancy. However, some methods increase the likelihood of twins

Ovulation Induction

Using medication to stimulate the ovaries to release more than one egg per cycle. Fertilization may occur naturally or via Intrauterine Insemination (IUI). If multiple eggs are fertilized, twin pregnancy becomes possible.

In Vitro Fertilization (IVF/ICSI)

Eggs and sperm are fertilized outside the body, and embryos are transferred into the uterus. In the past, multiple embryos were transferred to increase success rates, which also raised twin pregnancy chances. Today, with improved technology, doctors usually recommend transferring only one high-quality embryo (Single Embryo Transfer, SET) to reduce risks, prioritizing safety for both mother and child.

FAQs About Having Twins

Q: Can we choose to have twins directly?

A: It cannot be guaranteed 100%. Doctors can only increase the chance of a twin pregnancy by transferring more than one embryo during the IVF process. However, the final outcome depends on how many embryos successfully implant, which is beyond control. Physicians will also take into consideration the risks and potential complications of a twin pregnancy, based on each individual’s health condition and body structure.

Q: Is having twins more expensive than a regular pregnancy?

A: IVF costs may not differ much, but the expenses for prenatal care, monitoring, and delivery are higher because twin pregnancies are high-risk and require special care.

Q: Can we choose the gender of the twins?

A: During IVF, Preimplantation Genetic Testing for Aneuploidy (PGT-A) can be used, which reveals the embryos’ sex before transfer. However, the primary purpose of this test is to ensure embryos are healthy and free of chromosomal abnormalities—not solely for gender selection.
