Human Development Timeline

This graph shows an overview of human development and details about embryonic development.

Start from the top of the figure and work your way down for more detail.

Note:
  • LMP - Last Menstrual Period, last day is used to calculate the clinical Gestational Age GA.
  • Fertilization - can only occur after ovulation, about the midpoint (day 14) of what would have been the next cycle. About 2 weeks different from GA.
  • All timings are only approximate.
  • The sequence is important.
  • Hormonal changes shown are those during a normal menstrual cycle.
  • Hormonal changes would be different following fertilization and implantation.
