When you say "found" OP, do you mean bumped into? found on Facebook? Or matched via a reputable clinic?
Using a reputable clinic means the donor can be screened for a range of health disorders, (including STD's). However, as far as I know, the personal information they give you is limited.
If you don't use a clinic, and go the DIY route, there are all sorts of health issues and how can you be sure of anything he tells you about himself anyway? Even clinics don't do due diligence about a donors background apparently.
This news letter discusses the matter in the context of consumer fraud. That agencies take a man at his word without further corroboration is concerning.
"For one thing, the Supreme Court of Georgia decided that a case against Xytex, a large sperm bank based in Atlanta, could proceed.
The case involves Donor 9623, who claimed in his donor profile that he had an IQ of 160, was working on his PhD in neuroscience engineering and had no health problems. But when Donor 9623's name was accidentally releasedd_ to some families in 2014, and those families looked him up, the truth came out: he was a college dropout who had been diagnosed with schizophrenia and jailed for burglary."
