The gamete coming from the male gets energy from the fructose surrounding it. After it fuses with the gamete from the female it is sustained by oestrogen and progesterone until the blastocyst attaches, soon after that the placenta begins forming and transferring nutrients from the mother. That should be known by most people who studied reproduction during biology classes in school.
