This is described as an early human zygote as the male and female pronuclei have not yet combined to form a single nucleus.

At this stage in vivo:

  • there would still be granulosa cells and spermatozoa attached to the zone pellucida.
  • the zygote floats freely within the uterine tube.
  • The cell is preparing for the first mitotic division.
