Can you ovulate twice in one cycle?

Bottom lineYou can't ovulate twice at separate times in one cycle (the progesterone surge after ovulation prevents another release until the next cycle), but you can release two eggs within the same 24-hour ovulation window, which can lead to fraternal twins. So ovulation is a single window per cycle even if more than one egg is released; genetics, older age, higher BMI, and fertility treatments raise the chance of releasing two.

You can't ovulate twice at separate times in one cycle, but you can release two eggs within the same 24-hour ovulation window. This distinction explains both fraternal twins and some fertility myths.

What's actually possible

• Multiple ovulation: two (or more) eggs can be released during a single ovulation event, within about a day of each other. If both are fertilized, this leads to fraternal (non-identical) twins.
• A second, separate ovulation later in the same cycle: this does not happen. Once ovulation occurs, the resulting progesterone surge prevents another release until the next cycle.

Why the confusion

People sometimes have irregular bleeding or two surges close together and assume two separate ovulations. In reality, ovulation is a single window per cycle, even if more than one egg is released in it.

What raises the chance of releasing two eggs

• Genetics (a family history of fraternal twins)
• Older age and higher BMI
• Fertility treatments

Why it matters

It means your fertile window is still a single span per cycle, so timing advice doesn't change. It also explains how fraternal twins occur naturally.
