I graduated as an MD from the University of Copenhagen in 1989 and defended my PhD and Doctor of Science theses in 1995 and 2002, respectively. In 1999-2000, I spent a year as a visiting scientist at the National Cancer Institute in Bethesda, MD. Since 2012, I have been an adjunct professor of sexual health epidemiology at the University of Aalborg, Denmark.
Over the years I have been the author/coauthor of around 180 peer-reviewed research articles, scientific letters and book chapters covering several research areas, with particular focus on cancers, autoimmune diseases, and sexual health. In recent years, a number of my publications have dealt with the sexual and health-related consequences of male circumcision.
In 2011, together with two Danish colleagues, I published a study in The International Journal of Epidemiology in which we showed that circumcised men are at 3-fold increased risk of experiencing difficulties reaching orgasm compared with intact men. Our study also showed that women with circumcised male partners experienced significantly more trouble reaching orgasm, more pain during intercourse, and more often felt their sexual needs were incompletely met than women with intact male partners.
In 2013, I led an international coalition of 38 professors in Europe and Canada, including the presidents of several national medical associations and societies of pediatricians and pediatric surgeons, whose opposition to the 2012 policy on infant male circumcision by the American Academy of Pediatrics appeared in the journal Pediatrics.
In October 2014, I was an invited speaker at a hearing in the Danish parliament about the acceptability of circumcising healthy boys (7 min video with English subtitles).
In January 2015, my statistician and I published a scientific paper in the Journal of the Royal Society of Medicine, which linked infant male circumcision to a doubled risk of infantile autism in boys under the age of 5 years.
In May 2016, together with bioethicist Brian D. Earp, I authored a scientific paper in the journal Global Public Health, in which we addressed a number of conceptual and scientific problems in the United States Centers for Disease Control and Prevention’s (CDC) draft of the first-ever federal recommendations regarding male circumcision.
In December 2016, my statistician and I showed that childhood male circumcision is associated with a 16-26 times increased risk of meatal stenosis, a pathological narrowing of the urethral opening at the tip of the penis. Our findings were published in a scientific article appearing in the journal The Surgeon.
