Products of conception
Products of conception, abbreviated POC, is a medical term used for the tissue derived from the union of an egg and a sperm. It encompasses anembryonic gestation (blighted ovum) which does not have a viable embryo.
In the context of tissue from a dilation and curettage, the presence of POC essentially excludes an ectopic pregnancy.
