Examples

  • The term 'preimplantation' refers to the crucial period before the embryo attaches itself to the uterine wall.

  • With preimplantation genetic diagnosis, it would be a 1 00 percent match.

  • A preimplantation embryo of about 150 cells is produced by cell division following fertilization.

  • Preimplantation diagnostic tests opened the way for identifying the sex of an embryo simply for the desires of the parents.

    Academic text (2005)
  • Flow cytometry (sperm sorting) and preimplantation diagnostic tests of embryos (during in vitro fertilization) are now available.

    Academic text (2005)
  • The science behind the procedure is a technique called preimplantation genetic diagnosis (PGD), which takes a cell from embryos produced by a couple in vitro and screens them for possible inherited genetic diseases.

    Academic text (2011)
  • One clinic estimates the cost of preimplantation genetic diagnosis during in vitro fertilization at $10,480, not including all costs (Fertility Institutes, n.d.b).

    Academic text (2005)
  • During the preimplantation stage, the embryo undergoes several cell divisions before it implants in the uterus.

  • Scientists study the preimplantation phase to understand early embryonic development and identify potential genetic issues.

Morphology

preimplantation = implantation (transparent) = pre + implant + ation

The prefix 'pre-' straightforwardly marks the period before implantation, so the noun means 'the stage before implantation'.

Etymology

Preimplantation comes from pre- 'before' plus implantation, from a word meaning 'to plant' like plant. It names the 'stage' before an embryo is 'planted' into the uterus, which explains its modern meaning as that early period.
