Reproductive Medicine: Infertility affects 12% to 18% of couples globally, and while it has often viewed as a women’s health problem, men actually contribute to around half of the cases. Male infertility is on the increase unknown to many due to a variety of reasons and causes.

A new male fertility test based on Cornell research could help predict which men might need treatment and which couples might have success with different forms of assisted reproduction.
Dr Alexander Travis, Professor of reproductive biology at the Baker Institute for Animal Health and the test’s inventor told Thailand Medical News, “The ‘Cap-Score’ test is designed to provide information on the man’s fertility that they never had before. Now the doctors can discuss these results with the couple, and help them choose the personalized treatment pathway that is right for them to try to get pregnant, including how to improve the man’s fertility.”
The new research was published in the Journal: Reproductive BioMedicine.

The novel Cap-Score is a diagnostic test approved for use by medical doctors in all 50 states; the technology has been licensed to Androvia LifeSciences, LLC, a fertility research company co-founded by Travis, its chief science officer, in 2015. Travis holds equity in the company.
The Cap-Score quantifies the ability of sperm to undergo a process called “capacitation,” which enables the sperm to fertilize an egg. Only sperm that capacitate are capable of fertilizing. By contrast, traditional male fertility exams rely primarily on semen analysis, which counts sperm and assesses whether they swim and look normal.
Dr Travis added, “Fertility exists in degrees; as long as a man produces some sperm that swim, he has some level of fertility. But it is the functional ability of those sperm to fertilize an egg that influences the odds that a couple will become pregnant.”
The research included prospective clinical pregnancy outcomes data from six fertility clinics. Prospective tests are important when evaluating a new diagnostic procedure because they show the ability to predict what will happen for patients.
Dr Travis said Cap-Score’s predictive ability “held true across different age ranges for the female partner.” This is important because there are many well-known impacts of maternal age on a couple’s fertility. The new data shows that the man’s fertility plays a key role in whether a couple will be able to conceive, even if they might have delayed having children and are older.
The study team also compared Cap-Score results from more than 2,000 men having fertility exams at 22 clinics against results from a control group of fertile men with a pregnant partner or young baby. Cap-Scores from the fertile men showed an expected bell-shaped curve. In contrast, the vast majority of men questioning their fertility had scores below the mean of the fertile population.
The team additionally examined the relationship between traditional semen analysis results and impaired capacitation.

Dr Travis further added, “Men are often assumed to be fertile if they have enough normal-looking sperm that swim but we found that almost two-thirds of the men who had low Cap-Scores passed the traditional semen analysis.”
Currently infertility and most male infertility cases remain unexplained due to a lack of diagnostic testing. Not only does this place the onus of expensive and often invasive testing on women, it also may prompt couples to try expensive procedures that might be inappropriate for their situation. The Cap-Score can now provide crucial missing information to help guide their choices.
Dr Travis said, “Couples and physicians have had to make important decisions about their fertility without all the information they needed. This has caused a lot of anxiety and pain - physically, financially and emotionally.”
Utilizing the Cap-Score, physicians and couples can make informed decisions about whether to try to conceive unassisted or choose one of several medical approaches. The results can also be used to identify which men might benefit from treatment to improve their fertility, including changes in lifestyle, nutritional supplements or surgery.
