Some weeks back, I came across a case report published in in the journal Ultrasound in Obstetrics and Gynecology . However, the case report observed that the twin pregnancy was uneventful and resulted in the delivery of live healthy babies. It concluded that a phenomenon known as superfetation had occurred.

It happens when there is fertilization of an ovule by a sperm cell while a conceptus is already present in the womb. I thought so and dug deeper in the literature to realize that superfetation had actually been extensively reported in animals . The phenomenon of superfetation in animals has long been speculated as far back as fourth century B. C by Aristotle.

Back to Pregnancy. Yes, although the risk of getting pregnant in this way is very low. If you want to avoid getting pregnant, you should use contraception.

As soon as the penis is erect, before the man ejaculates, a liquid called pre-ejaculate is produced. This liquid can contain thousands of sperm. Men have no control over the production of this liquid.
