Most creatures reproduce though the female, with the male providing fertilization of her eggs while their still "in her oven". But male seahorses do somewhat the opposite --- the female deposits her sterile eggs into the male'ssperm-filled egg-pouch, where the eggs are fertilized and remain till they hatch.
