Everyone in my family says that it will either be me or my oldest sister who has twins. She is pretty much done having kids, so it falls on me. 

Now my boyfriend had an aunt or something who was kinda physic. She pointed at 3 kids one day before she passed and said they would have twins. One was my boyfriend. Both the other two has had twins sense then.

I know maternal twins are caused by the release of two eggs, but identical twins are caused by the splitting of a fertilized egg.

So my question is: Can a guy cause identical twins?
