Platypus fertilisation occurs internally.

The 2 fertilisation's are external fertilisation, or internal fertilisation. External fertilisation is the type frogs do.
The oviduct is the only way through which the sperm may reach the egg for fertilisation to happen. If the oviduct is blocked, then the sperm cannot reach the egg and so fertilisation cannot happen, so the woman cannot have a child without an IVF.
