Am a married man in his 50's. Already have three children through marriage. I currently have sperm in cryogenic storage and am looking to donate it to interested parties as soon as possible. I will ship it to the fertility clinic of your choosing just as soon as the donor / recipient paperwork is completed. Interested in being a donor only. I am a Caucasian heterosexual six-foot tall whose family has no instances of any genetic diseases. Since AI and IVF can be very expensive, please only those seriously interested parties should respond. Please reply ASAP if interested.
