যমজ সন্তান সম্পর্কে কিছু অজানা তথ্য | DR. SUTAPA SEN

Twin pregnancies occur when a woman conceives and carries two babies instead of one. Let's explore how these pregnancies occur, their incidence, and some interesting facts about twins:
1. Types of twins: There are two main types of twins: fraternal (dizygotic) and identical (monozygotic). Fraternal twins result from the fertilization of two separate eggs by two different sperms, while identical twins occur when a single fertilized egg splits into two embryos. Fraternal twins are more common than identical twins.
2. Determining twin pregnancy: Twin pregnancies can be detected through ultrasound imaging or other prenatal screening methods.
3. Chorionicity and amnionicity: In cases of identical twins, it's important to determine chorionicity (placental sharing) and amnionicity (amniotic sac sharing).
4. Incidence of Twin Pregnancies: The incidence of twin pregnancies varies across populations and is influenced by factors such as maternal age, genetics, and assisted reproductive technologies (ART). On average, the occurrence of twins in natural pregnancies is about 1 in 80 pregnancies.
5. Interesting Facts: a. Identical twins have the same DNA but can have slight differences due to epigenetic factors, environmental influences, or random mutations during development. b. The likelihood of having twins increases with maternal age, as older women are more likely to release multiple eggs during ovulation. c. The region with the highest incidence of twins is Africa, particularly Nigeria, while the lowest rates are found in Asia. d. Twins can be either mirror image twins, where their physical features are exact reflections of each other (e.g., hair whorls, birthmarks), or have noticeable differences. e. The birth order of twins can be determined by their position in the womb, with the firstborn being closer to the cervix and the second-born closer to the uterus.
Obstetricians and healthcare providers will closely monitor the progress of the pregnancy and take appropriate steps to ensure the health and well-being of both the mother and the babies.
