hi.A donor may donate sperm as an anonymous or non-anonymous donor through a clinic known as a sperm bank
or through a third party or broker who makes arrangements between sperm donors and recipient women, known as a sperm agency. A sperm donor may also donate directly to the recipient and may be known to her as a friend or non-blood relative. This may be done privately, or through a sperm bank or fertility
clinic. In some cases, informal sperm donation is not recognised in law, and in many cases informal sperm donors are also the legal father, although the rights and responsibilities this status confers may be ignored by both the donor and recipient.Laws vary between countries and states as regards the anonymity or otherwise of clinic donors.
