Sperm Cage 

When you seek out a man with the sole intent of getting impregnated. Especially so if the man is very successful, e.g. pro athlete, movie star, musician etc.

Man 1: Staci got on that first round draft pick without missing a beat!

Man 2: Staci got him in that Sperm Cage.

Man 1: Good thing he got that signing bonus.
