Quizplus · Accepted Answer

The chance of conceiving twins increases with parental age primarily due to irregular ovulation and the use of fertility drugs. As women age, their ovulation can become more irregular, sometimes leading to the release of multiple eggs during a cycle, which can result in fraternal twins if more than one egg is fertilized. Additionally, the use of fertility drugs to stimulate ovulation can also increase the likelihood of multiple eggs being released and fertilized.
