Ethical issues with too many siblings from same donor

Living94

A family friend and her partner used Fairfax Cryobank and had a successful pregnancy. She is a lawyer, and said that some concerns have been raised about the # of siblings by sperm donors there are in the area/country. The concern is that there could be 30-100+ siblings and this could one day lead to issues of incest, etc. if someone unknowingly became involved with a half sibling. I'd like to hear Fairfax's thoughts on this as well as other folks utilizing donor sperm. Thanks!

Ineresting! I have found 9-11 half siblings for my children. I called because they are almost all on the Eastern part of the US. I was told there were between 15-20 reported pregnancies. I have found that geographically these other families are within a two hour ride from me.
