Researchers Kimberly Elford and Paul Claman at the University of Ottawa have revealed a gruesome circumstance explaining one reason why some otherwise healthy women are left infertile after abortions.

In a case study published in the April issue of the journal Fertility and Sterility, the researchers note that fetal bone fragments can lodge into the muscular tissue in the uterus, concealing them from hysteroscopes (tube cameras) which are normally used to detect remaining baby parts after abortions.

With the use of ultrasound, doctors were able to identify the lodged aborted baby bones and scrape them away, after which patients with related infertility were able to conceive. The researchers note that bone will be present in all unborn children from 12 weeks’ gestation.

An analysis of common abortion methods reveals clearly how bone fragments could be lost in the uterus after abortions. Abortions after the third month of pregnancy, when bone tissue has already formed, usually require the bones of the unborn child to be broken. Dilation and curettage abortions use a hook-shaped knife (curette) which cuts the body into pieces prior to evacuation.
