_88650680_031604668-1

The occurrence, known as heteropaternal superfecundation, is rare with few publicly known about.

It happens when a woman’s eggs are fertilised by two men within a short period of time.

  • ‘Superfecundation’ refers to the fertilisation of multiple eggs from separate acts of intercourse, and ‘heteropaternal’ means they are fertilised by more than one father
  • It can happen when a woman produces multiple eggs in one and they are fertilised by different men within a few days
  • It can also happen if a woman ovulates twice within a short period of time and both eggs are fertilised by different men
  • Turkish media reported a similar case in 2010 involving twin boys.
