Almost 30% of couples who can’t get pregnant don’t know why (diagnosis: unexplained infertility). New research shows one possible cause of unexplained infertility in men: DNA damage in individual sperm.
About 50,000 couples in the UK require fertility treatments every; worldwide, about one million couples need help getting pregnant.
“With one million couples worldwide requiring fertility treatment, these new research findings will give many fresh hope of having a family,” says Professor Sheena Lewis of the School of Medicine, Dentistry and Biomedical Sciences at Queen’s University Belfast.
If you’ve been diagnosed with unexplained infertility, you might try alternative therapies to increase your chances of getting pregnant, such as acupuncture for fertility. Talk to your health care provider about how to care for damaged DNA in sperm – which is one possible cause of unexplained infertility.

And, here’s the research information about sperm damage that may help you figure out how to get pregnant.
Research on Unexplained Infertility in Males
“The majority of couples experiencing problems with fertility are able to receive an explanation for their infertility,” says Professor Lewis. “These causes range from low sperm count, poor sperm motility in the man to blocked fallopian tubes or endometriosis in the woman. Once the causes for infertility have been established the appropriate course of assisted conception treatment can be undertaken.”

Couples often invest a lot of time and money in fertility treatments, such as intrauterine insemination (IUI). This new research shows that there may be a possible cause for unexplained infertility in men – which can help couples find suitable fertility treatments. This can increase their chances of having a baby.
High Sperm DNA Damage May Cause Infertility
New research from Queen’s reveals the cause of infertility for 80% of couples who can’t get pregnant and don’t know why. Up to one third of these couples are diagnosed with unexplained or idiopathic infertility. This means that, using current fertility and health tests, neither partner has been diagnosed with any detectable problem.
This new research reveals that 80% of the 239 couples in this study who were diagnosed with unexplained infertility have a detectable cause known as high sperm DNA damage.
Also, this is the first study to show that the chances of having a baby after in vitro fertilization (IVF) is closely related to the amount of DNA damage a man has in each of his sperm. A little damage is normal in the sperm of men who are fertile. But if there is high sperm DNA damage (more than 25% of damage per sperm), then the couples’ chances of getting pregnant are reduced – even with some forms of fertility treatments.
This research was carried out using a unique test for male fertility called the SpermComet™.
“We at Queen’s have developed the SpermComet™, which is a unique test for male infertility that measures damaged DNA in individual sperm,” says Professor Lewis. “It provides all couples with specific information about the causes and extent of their infertility. This test can predict the success of infertility treatments and fast-track couples to the treatment most likely to succeed, leading to reduced waiting times and improved chances of success.”
Professor Lewis, in partnership with Queen’s venture spinout arm, QUBIS, has set up a company called Lewis Fertility Testing Ltd, which is already marketing the test.
If you’re having trouble getting pregnant, remember that fertility doctors and reproductive endocrinologists make mistakes. One fertility specialist can miss something that another could catch right away. Missed diagnoses and misdiagnoses aren’t necessarily because some doctors are better than others; it just means that different doctors have different education, experiences, and specialties.
If you’re not satisfied with your doctor’s opinion or diagnosis of unexplained infertility, you need to get a second opinion.
