Conceiving fraternal boy-girl twins, also known as dizygotic twins, is a unique pregnancy outcome that has sparked interest among couples seeking a family with both genders. These twins develop from two separate eggs fertilized by two different sperm and share only 50% of their genetic material, making them biologically different individuals.
The probability of conceiving dizygotic twins is influenced by various factors such as maternal age, genetic predisposition, and lifestyle choices. Historically, the use of fertility treatments like IVF has increased the incidence of multiple pregnancies, including dizygotic twins.
