Organ and tissue harvesting and sale from aborted fetuses in Western countries

I believe this is still largely a taboo subject! Many Westerner probably have heard of organ harvesting going on in China, but what about in Western countries?

To what extent is this actually happening in Western countries?

I am not sure the ethical issues surrounding this subject have been adequately addressed.

Caveat: I am not an expert on this subject and I did not have the time to do more research on it. However, this controversial subject has been in the public discourse for decades!

Yes, fetal tissue and organs might be a life saver or an important medical treatment option to some patients suffering from severe diseases etc. However, how far can we or should we go?

Cui bono? Who is profiting from it? 

E.g. are some women induced or incentivized to get pregnant and then to have an abortion for medical purposes? Is this legal? What are the applicable regulations etc.?

"... CMP [The Center for Medical Progress, Inc.] and Daleiden are responsible for the 2015 undercover video series documenting the harvesting and sale of aborted fetal body parts at major abortion clinics across the country. Amici’s investigative reporting exposed illegal transfers of aborted human fetal tissue in violation of 42 U.S.C. § 289g-2, coercion and abuse of pregnant patients through violations of informed consent and non-medical changes to patient treatment, and the use of illegal partial-birth abortions and even infanticide in the trafficking of later-gestation human fetuses for experimental use. Amici’s undercover videos with Planned Parenthood leadership identified the criminal companies DaVinci Biosciences and DV Biologics, who admitted guilt for illegally selling human fetal tissue for valuable consideration from abortions at Planned Parenthood in southern California and were shut down in a $7.8 million settlement with the Orange County District Attorney ..."

Here is another example of the sometimes complicate ethics involved:
"... A twenty-six year old woman and her family were devastated when her father was diagnosed with Alzheimer's disease. The man whom they loved was gradually being reduced to a man who at fifty-two years of age could barely care for himself. Desperate to stop the heartrending deterioration of the father, the family repeatedly suggested that the woman, the only female of childbearing age, become pregnant for the sole purpose of aborting the fetus. The family hoped that the doctors could then transplant the brain tissue of the aborted fetus into the father's brain, thereby alleviating many of the destructive symptoms of Alzeheimer's disease. ..."
