  • Believe donor would have been around age 31 in 1985. Procedure was performed under Dr Gottesfeld. Also believe semen was transported in a taxi cab right before insemination which would have taken place feb/march 1985. Might have been blood type O+. There may have been a woman in the office by the name of Jan.

  • FOUND! Used 23&me and found a half sibling who was part of the donors intact family. From there it was easy to find the donor. The half sibling immediately deleted his info after my daughter contacted him. Perhaps he had no idea that his dad was a sperm donor. My daughter is going to leave it alone for awhile at least. But she has now seen photos of the donor and his children. OLD INFO He was a resident at the time. The sperm was transported to the clinic/hospital by taxi. This was the office of Doctor Gottesfeld. There were three of them - Kenneth and Stuart were brothers. Kenneth died in a skiing accident in the 1990s. The third doctor was the son of either Stuart or Kenneth. I can't find any mention of any of them still practicing medicine. The office seems to have shut down. Stuart would be quite old, probably dead, but the son would be in his 60s. There are others who used Dr. Gottesfeld but I suspect people are spelling the name differently. There is a Marshall Gottesfeld who is an OB/GYN in Denver who is Stuart's son, but he graduated in 1991, so he is not the doctor who was involved in my care. The facility was actually the office, or on the weekends, the emergency room at Rose Hospital. I have listed it as the Health Sciences Center because that seems like the closest fit. They were just a couple of blocks apart. The nurse kept the name of the sperm donors in a book that only she had access to. The doctors did not know. After my daughter was born, and had medical difficulties, I contacted the office to find out more about the donor. They told me he was a resident, that he had moved on and that they would not be able to find him. Of course, this could not have been true, but I didn't press it. I believe I signed something saying that I would not try to obtain the name of the sperm donor.
