Seminal Motility

Seminal motility is an aspect of fertility, and refers to the ability of sperm cells to move in medium (and in the womb). Increasing sperm motility can improve fertility in men who are otherwise infertile.

Human Effect Matrix

The Human Effect Matrix looks at human studies (it excludes animal and in vitro studies) to tell you what supplements affect seminal motility
Grade Level of Evidence
Robust research conducted with repeated double-blind clinical trials
Multiple studies where at least two are double-blind and placebo controlled
Single double-blind study or multiple cohort studies
Uncontrolled or observational studies only
Level of Evidence
? The amount of high quality evidence. The more evidence, the more we can trust the results.
Outcome Magnitude of effect
? The direction and size of the supplement's impact on each outcome. Some supplements can have an increasing effect, others have a decreasing effect, and others have no effect.
Consistency of research results
? Scientific research does not always agree. HIGH or VERY HIGH means that most of the scientific research agrees.
Notes
grade-c Minor Very High See all 3 studies
Alongside improvements in all seminal parameters, ashwagandha is able to increase seminal motility as well; both are thought to underlie pro-fertility effects.
grade-c Minor Very High See all 3 studies
Requires more evidence to assess potency, but it does appear to reliably increase seminal motility
grade-c Minor - See study
Sperm motility appears to be increased, with more efficacy in those with lower baseline motility and improvements averaging 44.4%
grade-c Minor Very High See 2 studies
An increase in seminal motility is observed following mucuna ingestion
grade-c - - See study
grade-c - Very High See 2 studies
The best evidence to date does not support a role for saffron supplementation in increasing seminal motility.
grade-c - - See study
grade-d Notable - See study
Preliminary evidence suggests a 47.3% increase in seminal motility seen with three months supplementation of ginger to infertile men.
grade-d Notable - See study
One uncontrolled study found a notable improvement in seminal motility relative to baseline
grade-d Minor - See study
Seminal motility is increased 50-100% in infertile men supplementing with D-aspartic acid
