Sperm donors are well-adjusted men: study

NEW YORK - Men who pass a screening process and donate to sperm banks in Sweden score better on personality measures, such as responsibility, confidence and self-acceptance, than other men in their peer group, according to a Swedish study.

Sweden was the first country to pass a so-called non-anonymous law, which entitles children to contact the sperm donor if they choose. Britain, Australia and other nations also require that donors consent to being contacted.

Sperm donors are well-adjusted men: study

The United States allows donors to remain anonymous and for them to get paid, unlike Sweden, where men can only volunteer.

The non-anonymous laws could be a problem for both sides since nobody can prepare themselves for their reactions if a child decides to contact the biological father, said Gunilla Sydsjo, lead author of the study and a professor at Sweden's Linkoping University.

"A decision made at the age of 25 might be crystal-clear for the individual at that time but might take on other dimensions 20 years later," she says.

"We have, in this study, shown that the men who are accepted for the program were all in the normal range of character and also demonstrated a mature personality and a stable character."

The study, published in the British obstetrics and gynecology journal BJOG, looked at 115 men who donated sperm at clinics in Sweden between 2005 and 2008, comparing them with men of similar age who did not attempt to donate sperm.

Donors in Sweden go through a screening process that weeds out men with psychological or health problems. The study questionnaire asked about behaviors, emotions and social skills.

On two measures, self-directedness and cooperativeness, the donors scored higher than the comparison group, showing that they pursue goals, stick to their values and take responsibility, researchers said.

The donors scored lower on one measure, called harm avoidance. "This indicates that the sperm donors described themselves as being less worried, uncertain, shy and less subject to fatigue," the researchers wrote.

All other personality traits, including persistence and novelty seeking behaviors, were similar between the two groups.

The results suggested that the donors would not be thrown if a child decided to contact them, said Robert Oates, president of the Society for Male Reproduction and Urology, who was not involved in the study.

"They will be able to handle it if in the future somebody comes to them and says, 'I am your donor child'," he added.

"I think the majority are just nice people who want to help people out. That may be a different personality from the 21-year-old college student who wants to make a lot of money."

Two recent studies have shown that uniting children with donor fathers is usually a positive experience, but the researchers wrote that they were not aware of any children in Sweden taking advantage of the transparency law to contact their biological fathers.
