TERMS TO KNOW
  • Human Chorionic Gonadotropin (HCG)

    A hormone secreted from the developing placenta(blastocyst) that prevents the destruction of the corpus luteum; the corpus luteum secretes estrogen and progesterone which prepares the female’s body for pregnancy.

  • Ectopic Pregnancy

    Also called tubal pregnancy, an ectopic pregnancy occurs when implantation occurs in the oviduct instead of the uterus. Ectopic pregnancies result in abdominal pain that will eventually cause the oviduct to rupture if the pregnancy isn’t terminated.

  • Endometrium

    The inner layer of tissue within the uterus; the deepest tissue layer of the uterus where the blastocyst implants itself.

  • Implantation

    A term used to describe when the blastocyst attaches to the endometrium of the uterus.
