Guide | Only 4% of Sperm Donor Applicants in the United States and Denmark Complete the Donation Process
Study finds rigorous sperm donor screening means few applicants complete the donation process
According to a study, only about 4% of men in the United States and Denmark successfully complete the sperm donation process, even after initially applying to become donors. Although many register online and undergo semen testing, they may not complete the process for reasons including poor post-thaw sperm quality, health conditions, failed infectious-disease testing, or ineligibility after genetic screening.
Despite the low figure, lead researcher Dr. Allan Pacey, professor of andrology at the University of Sheffield in the United Kingdom, emphasized that men should not be discouraged from donating. “A steady supply of donors is very important,” he said. “My advice is: Do not be discouraged by the low success rate. If you are interested in becoming a donor, undergo screening to see whether sperm donation is right for you.”
Study Background and Data
The study, published in Human Reproduction, examined the proportion of male applicants who successfully completed the donation process. Most previous research focused on the safety or viability of frozen sperm samples, while few studies examined applicant completion rates.
The findings showed that only about 4% of male participants in the United States and Denmark completed the sperm donation process. Dr. Pacey was not surprised. “When I ran a small sperm bank at the University of Sheffield, fewer than 4% of applicants ultimately passed screening. This shows how difficult donor screening is,” he said.
However, Dr. Michael Thomas, president of the American Society for Reproductive Medicine, was surprised by the success rate. “Only one in four applicants succeeded, far below the 20% to 30% I expected,” he said.
Significance: A Distinct View of the Sperm Donation Industry
Dr. Thomas said the study offers valuable insight into the sperm donation industry. “The sperm donation industry has not been studied this closely in recent years, and understanding how it operates is meaningful,” he said. However, the study evaluated data only from Cryos International, while many other sperm banks operate in the United States and elsewhere, which may limit how broadly the results apply.
Dr. Thomas also noted that Cryos applies very strict screening standards: “These data show that they do not accept everyone who applies.”
Changes in Donor Anonymity
With the popularity of commercial genetic-testing companies such as Ancestry.com and 23andMe, sperm donor anonymity is changing. Dr. Thomas noted: “Today, many people use genetic testing to discover connections with siblings or children conceived through sperm donation, raising complex questions about genetics.” He believes this change means many donors are gradually losing anonymity.
Geographic Differences: Denmark and the United States
The study also found that men in Denmark were more likely to complete the donation process, with a success rate of 6%, compared with 1% in the United States. Dr. Pacey said this difference deserves attention: “If we can optimize donor recruitment for different countries, we may be able to increase the number of donors.”
Future Research
Dr. Pacey said future studies will examine why so many men stop the donation process and explore differences between Denmark and the United States. “We hope more detailed research can improve donor recruitment in both countries.”
