Women who carry a genetic tendency for hyperovulation (releasing more than one egg during ovulation) are more likely to conceive fraternal twins. This trait can be passed down through generations, making twin pregnancies more common in certain families.
If a woman’s mother or grandmother had twins, her chances may be higher compared to the general population.
Age and Its Surprising Influence
Age plays a significant and somewhat surprising role in twin pregnancies. While fertility generally declines with age, the likelihood of releasing multiple eggs can actually increase during the later reproductive years.
Women between the ages of 35 and 39 statistically have a higher chance of conceiving twins. This is believed to be linked to hormonal changes, particularly increased levels of follicle-stimulating hormone (FSH), which can trigger the release of more than one egg.
However, pregnancies occurring after age 50 are extremely rare and typically involve advanced medical support. In these cases, careful monitoring and specialized care are essential to ensure the health and safety of both mother and babies.
