be academically successful, with active friendship networks, strong family bonds, and overall high ratings of well-being. It is estimated that over 80% of adolescents feel they can confide in their mothers, and almost all regard their mothers to be good role models. Motivation vs reluctance to donate A systematic review came to the result that altruism and financial compensation are the main motivations to donate, and to a lesser degree procreation or genetic fatherhood and questions about the donor's own fertility. Financial compensation is generally more prevalent than altruism as a motivation among donors in countries where the compensation is large, which is largely explained by a larger number of economically driven people becoming donors in such countries. Among men who do not donate, the main reason thereof has been stated to be a lack of motivation rather than concerns about the donation. Reluctance to donate may be caused by a sense of ownership and responsibility for the well-being of the offspring. Support for donors In the UK, the National Gamete Donation Trust is a charity which provides information, advice and support for people wishing to become egg, sperm or embryo donors. The Trust runs a national helpline and online discussion list for donors to talk to each other. In one Danish study, 40% of donors felt happy thinking about possible offspring, but 40% of donors sometimes worried about the future of resulting offspring. A review came to the result that one in three actual donors would like counselling to address certain implications of their donation, expecting that counselling could help them to give their decision some thought and to look at all the involved parties in the donation. A systematic review in 2012 came to the conclusion that the psychosocial needs and experiences of the donors, and their follow-up and counselling are largely neglected in studies on sperm donation. Ethical and legal issues Anonymity Anonymous sperm donation occurs under the condition that recipients and offspring will never learn the identity of the donor. A non-anonymous donor, however, will disclose his identity to recipients. A donor who makes a non-anonymous sperm donation is termed a known donor, an open identity donor, or an identity release donor. Non-anonymous sperm donors are, to a substantially higher degree, driven by altruistic motives for their donations. Even in the case of anonymous donation, some information about the donor may be released to recipients at
