  • At this facility, I delivered 16 samples of fresh semen and then one sample--the last one I donated--that was frozen before being used to inseminate a woman. I beleive this is because they changed from fresh to frozen semen at this facility while I was working there. My hair was dark brown at the time of my work at this facility, and is mostly gray now.

  • The procedure was performed on May 18th, 1989 with fresh sperm (not frozen). I have no profile or ID number, only a receipt and contract. I am hoping these few details and the date of donation/insemination will be sufficient to establish a match.

  • I was part of Doctor H. Stewart Kimball�s �stable,� as he liked to call it. Fresh, not frozen, samples were delivered to his office or to various other doctors around the Bay Area as per his direction. The samples delivered to his office were used in that building or taken to other doctors, sometimes to San Francisco or Contra Costa County including this Walnut Creek office. I have date and time records of each donation and notation of where it was delivered. Where the sample was finally administered I have no way of knowing.
