Superfetation, a Rare Phenomenon When Women Get Pregnant Again While Pregnant

Suara.com – When a woman becomes pregnant, she stops ovulating, or the process of releasing a mature egg from the uterus that is ready to be fertilized by sperm. However, in some rare cases, ovulation can still occur when a woman is pregnant. And if the egg is successfully fertilized, she can get pregnant again even though she is pregnant.

Reporting from Parenting Firstcry, this phenomenon is called superfetation, or often called multiple pregnancy, which is where more than one fetus grows in the womb, but each of these fetuses is fertilized separately and at different times.

Superfetation makes a mother pregnant with twins, with different gestational ages, and sometimes even different birth dates. So, when a baby is born (usually delivered by caesarean section), the baby will have a different weight, height, and even blood type.

The phenomenon of superfetation is very common in animals, Superfetation can also occur among animals. such as mice, kangaroos, rabbits, cats, and sheep.

In humans, cases of superfetation are very rare. Even so, it does not rule out the possibility of an unknown and misdiagnosed case of superfetation as a case of ordinary twin pregnancies.

Reporting from Bright Side, one case of superfetation occurred in Australia in a woman named Kate Hill. She was pregnant twice within 10 days. Kate gave birth to 2 baby girls – Charlotte and Olivia, who have been classified as twins. Although born on the same day, the two babies have a 10-day difference in conception time, so they both have different sizes, weights, and developments.

What you need to know, superfetation is different from regular twin pregnancies. In a normal twin pregnancy, one or more eggs from the same menstrual cycle are fertilized by sperm, and two or more fetuses are formed that live and develop at the same time.

Whereas superfetation occurs when two eggs from different menstrual cycles are fertilized and develop in the uterus at different times. As a result, there is a difference in the maturity of the fetuses, as they have been fertilized at different weeks or months.
