Superfetation is a rare phenomenon where a woman gets pregnant while already pregnant, resulting in two simultaneous pregnancies due to a second egg being fertilized and implanted.
Superfetation is a rare occurrence where a woman becomes pregnant again while already pregnant. This phenomenon is extremely uncommon in humans with only a few documented cases. The evidence indicates that it involves the formation of a new embryo during an existing pregnancy. Although possible, it is a very rare event and not a typical physiological process.
