A 2026 study of 31 men found that AlphaSperm, a male fertility supplement, did not improve standard sperm measurements like count or movement after 9 months of daily use. However, Gram Research analysis revealed the supplement caused changes to chemical tags on sperm DNA called methylation, particularly in older men with fertility problems. These epigenetic changes suggest supplements may affect sperm in ways that conventional fertility tests cannot detect, though whether these changes actually improve fertility remains unclear.
A new study looked at how a male fertility supplement called AlphaSperm affects sperm health in three groups of men: young and healthy, young and infertile, and older and infertile. Researchers found that while the supplement didn’t improve traditional sperm measurements like count or movement, it did cause changes to the chemical tags on sperm DNA. These chemical changes, called epigenetic modifications, were especially noticeable in older men with fertility problems. The findings suggest that fertility supplements may work in ways that standard sperm tests cannot detect, though more research is needed to understand if these changes actually help men have children.
Key Statistics
A 2026 research article of 31 men found that AlphaSperm supplementation did not significantly alter conventional semen parameters or sperm DNA fragmentation within any of the three study groups after 9 months of daily treatment.
According to research reviewed by Gram, the supplement induced regional sperm DNA hypermethylation in all groups, with 5 genes known to correlate with male infertility showing increased methylation specifically in the older infertile men group.
A 2026 multi-institutional study found that male fertility supplement-induced epigenetic changes in sperm DNA occurred independently of changes in standard semen analysis measurements, suggesting supplements may work through mechanisms not detectable by conventional fertility testing.
The Quick Take
- What they studied: Whether a male fertility supplement changes sperm quality and the chemical markers on sperm DNA that affect fertility potential
- Who participated: 31 men divided into three groups: 11 young healthy men, 10 young men with fertility problems, and 10 men over 40 with fertility problems. All men took the supplement daily for 9 months.
- Key finding: The supplement did not improve standard sperm measurements like count, movement, or DNA damage. However, it caused changes to chemical tags on sperm DNA in all groups, with the strongest changes in older men with fertility problems.
- What it means for you: This research suggests fertility supplements may affect sperm in ways that regular sperm tests cannot measure. However, it’s unclear whether these chemical changes actually improve a man’s ability to father children. More research with larger groups and control groups is needed before making recommendations.
The Research Details
This was a prospective study, meaning researchers followed the same men over time and collected information as events happened. The study included men from multiple medical centers who took AlphaSperm supplement daily for 9 months. Researchers collected sperm samples at the start and after 9 months of treatment. They measured traditional sperm health markers using World Health Organization standards, including sperm count, movement, and DNA damage. They also performed advanced genetic testing to look at epigenetic changes, which are chemical modifications to DNA that don’t change the DNA sequence itself but affect how genes work. The researchers used a technique called methylation array analysis to identify regions of sperm DNA that had changed chemical tags, and they used computer tools to understand which biological pathways were affected by these changes.
Standard sperm tests measure obvious features like count and movement, but they may miss important changes happening at the genetic level. Epigenetic changes can affect fertility even when traditional sperm measurements look normal. This study used advanced technology to detect these hidden changes, providing new insights into how supplements might influence sperm health in ways that conventional testing cannot reveal.
This study has important limitations that readers should understand. The sample size was small, with only 31 men total across three groups. The study lacked a control group of men taking a placebo (fake supplement), which means researchers cannot be certain the changes were caused by the supplement rather than other factors. The study was published in a peer-reviewed journal, meaning other scientists reviewed the work before publication. However, the authors themselves acknowledge that the functional significance of the epigenetic changes needs further validation, meaning it’s unclear whether these chemical changes actually improve fertility.
What the Results Show
AlphaSperm supplementation did not significantly change standard semen parameters, which include sperm count, movement, and shape. DNA fragmentation, a measure of sperm DNA damage, also remained largely unchanged across all three groups. These findings suggest that the supplement does not improve sperm health in ways that conventional fertility tests can measure. However, the study revealed something unexpected: the supplement caused regional increases in DNA methylation, a chemical modification to sperm DNA, in all three groups of men. This hypermethylation was most pronounced in the older men with fertility problems. The researchers identified 5 genes whose methylation patterns are known to correlate with male infertility that showed increased methylation in the older infertile group, and 1 gene with increased methylation in the young healthy group.
The study used advanced gene ontology analysis to understand which biological pathways were affected by the epigenetic changes. This analysis revealed that the supplement-induced changes involved genes and pathways relevant to male fertility. The researchers also performed SpermQT testing, a clinical diagnostic tool, on all participants, though specific results from this testing were not detailed in the abstract. The fact that epigenetic changes occurred in all three groups, regardless of age or fertility status, suggests the supplement has consistent effects on sperm DNA chemistry across different populations.
Previous research has shown that male fertility supplements can reduce oxidative stress, which is harmful chemical activity in cells. However, whether these supplements actually improve fertility has been controversial and unclear. This study adds to that discussion by showing that supplements may cause measurable changes at the genetic level even when traditional sperm tests show no improvement. The finding that epigenetic changes occur independently of changes in semen parameters is novel and suggests that supplements may work through mechanisms that standard fertility testing cannot detect. This aligns with growing scientific understanding that epigenetic patterns play an important role in fertility potential.
The study had several important limitations. First, the sample size was small, with only 31 men total, which limits how much the findings can be generalized to larger populations. Second, the study lacked a placebo control group, meaning researchers cannot definitively prove the supplement caused the changes rather than other factors like diet, stress, or natural variation. Third, while the study identified epigenetic changes, it did not demonstrate that these changes actually improve fertility or lead to successful pregnancies. The researchers themselves noted that the functional significance of the observed methylation changes needs validation through further research. Finally, the study was conducted over 9 months, so it’s unknown whether the effects persist longer or whether they eventually lead to improved fertility outcomes.
The Bottom Line
Based on this research, fertility supplements may cause changes to sperm DNA that standard tests cannot detect. However, there is insufficient evidence to recommend AlphaSperm or similar supplements specifically for improving fertility. Men concerned about fertility should consult with a fertility specialist who can perform comprehensive testing and recommend evidence-based treatments. If men choose to take fertility supplements, they should do so under medical supervision and understand that changes to sperm DNA chemistry do not necessarily translate to improved fertility or pregnancy success.
This research is most relevant to men with fertility concerns, fertility specialists, and researchers studying male reproductive health. Men considering fertility supplements should be aware of these findings but should not assume the supplement will improve their fertility based on this single study. Women trying to conceive with partners taking supplements should understand that epigenetic changes do not guarantee improved fertility outcomes. Healthcare providers should be aware that fertility supplements may have effects not visible in standard sperm testing.
This study measured changes over 9 months of daily supplementation. However, it did not track whether these epigenetic changes led to improved fertility or successful pregnancies. Men should not expect immediate results from fertility supplements. If considering supplementation, realistic expectations should include waiting several months to see any potential benefits, combined with standard fertility testing and medical evaluation.
Frequently Asked Questions
Do male fertility supplements actually improve sperm count and movement?
This 2026 study of 31 men found that AlphaSperm did not significantly improve standard sperm measurements like count, movement, or DNA damage after 9 months of daily use, though it did cause chemical changes to sperm DNA.
What are epigenetic changes and why do they matter for fertility?
Epigenetic changes are chemical tags on DNA that affect how genes work without changing the DNA sequence itself. They correlate with fertility potential, and this study found the supplement altered these tags in ways standard sperm tests cannot detect.
Should men take AlphaSperm if they’re trying to have a baby?
This single study is insufficient to recommend AlphaSperm for fertility. While it shows the supplement causes epigenetic changes, it did not demonstrate these changes improve fertility or pregnancy success. Men should consult a fertility specialist for personalized advice.
How long does it take for fertility supplements to work?
This study measured changes over 9 months of daily supplementation. However, it did not track whether these changes led to improved fertility. Men should expect to wait several months and should combine supplementation with medical evaluation and standard fertility testing.
Why didn’t the study use a placebo control group?
The study lacked a placebo control, which is a significant limitation. Without a control group taking fake pills, researchers cannot definitively prove the supplement caused the observed changes rather than other factors like diet or natural variation.
