Spirulina supplementation may enhance male fertility

Spirulina may increase male fertility, suggests an exploratory trial from Iran. The study does not tell us much about how spirulina should work.


Spirulina supplementation may enhance male fertility


Study
Researchers at Shiraz University of Medical Sciences in Iran did an experiment with 40 men who wanted to become fathers, but turned out to be infertile. All men received 50 milligrams of clomiphene citrate, 500 milligrams of L-carnitine and 50 milligrams of elemental zinc (as 220 milligrams of zinc sulfate) every day for 12 weeks.

Half of the test subjects also took 2 grams of spirulina.

Results
Spirulina supplementation did not result in significant changes in sperm quantity and quality. If you want to see that statement explained in more detail, click on the table below.

Nevertheless, supplementation may still have an effect. Of the partners of the men in the spirulina group, 5 percent became pregnant. This was 0 percent in the control group.

Conclusion
You have to bear in mind that there were 20 men in both groups. So it is about 1 pregnancy. The researchers therefore argue for more research, with more test subjects.
