where does implantation of a fertilized ovum occur?
fundus
a related application of the principle of double effect is breastfeeding. breastfeeding greatly suppresses ovulation, but eventually an ovum is released. luteal phase defect, caused by breastfeeding, makes the uterine lining hostile to implantation and as such may prevent implantation after fertilization. some pro-choice groups have expressed concern that the movement to recognize hormonal contraceptives as abortifacient will also cause breastfeeding to be considered an abortion method.

beginning of pregnancy controversy
the reproductive function of the uterus is to accept a fertilized ovum which passes through the utero-tubal junction from the fallopian tube. the fertilized ovum divides to become a blastocyst, which implants into the endometrium, and derives nourishment from blood vessels which develop exclusively for this purpose. the fertilized ovum becomes an embryo, attaches to a wall of the uterus, creates a placenta, and develops into a fetus (gestates) until childbirth. due to anatomical barriers such as the pelvis, the uterus is pushed partially into the abdomen due to its expansion during pregnancy. even during pregnancy the mass of a human uterus amounts to only about a kilogram (2.2 pounds).
