A study into how women choose sperm donors via online websites has
revealed men who are intellectual, shy, calm and methodical are selected
to produce more children than those who are extroverted. It also
highlighted that women choose donors who have a higher income, even
though there is no requirement for ongoing parental support.
The study, Determinants of online sperm donor success: how women choose
by Stephen Whyte and Professor Benno Torgler from QUT's Queensland
Behavioural Economics Group, has been published by the international
journal Applied Economic Letters.
"Worldwide demand for sperm donors is so great an informal online market
has emerged in which offspring are being produced outside of the more
formal fertility clinic setting," said Mr Whyte.
"You would expect in an online setting, men would have to sell or
promote themselves to women, and extroverted men should be better at
doing that. But what we find is actually the opposite.
"In what we believe is the first study to include males who are donating
purely through unregulated websites and forums, we interviewed and
collected data from 56 men.
"This online donor market works quite differently to fertility clinics
in that it facilitates more interaction between the recipient and the
donor. This allows us to explore individual donor personality
characteristics and how likely they are to be chosen by women as their
donor.
"Women were far less likely to choose the sperm of fretful or socially
awkward men but at the same time those with lively, extroverted
personalities were also less successful in being chosen."
The participants for the study were aged between 23 and 66 and were from
Australia, Canada, the UK, Italy, Sweden and the USA. Data was
collected across 2012 and 2013 via online surveys of regulated (paid),
semi-regulated and online sperm donation forums and websites such as
Pride Angel.
"Research has previously shown humans are good at judging personality
traits as well as levels of intelligence with only minimal exposure to
appearance and behaviours, and our findings certainly seem to support
that," Mr Whyte said.
"We also found that 73 per cent of our participants who had children by
donation kept in touch via mail, email, phone, video link or even in
person with at least one of their donor children."
