WebEjaculated sperm are not ready to fertilize an egg when they enter the vagina. In response to the dilution of semen in the vagina, the levels of a protein called FPP (fertilization promoting peptide) start dropping. This results in the sperm starting to undergo several changes, which are collectively known as capacitation.
