Can Soybeans Boost Sperm?

Published in Diet and Fertility 2 mins read

Based on available research, soybeans do not appear to boost sperm concentration. In fact, some studies suggest a potential association with lower sperm levels.

What the Research Says

One study specifically investigated the link between soy consumption and sperm quality.

Study Details

  • Participants: 99 male partners of subfertile couples.
  • Duration: Observed over a three-month period.
  • Observation: Compared soy intake levels among the men.

Key Finding

The study found that men in the highest category of soy intake had sperm concentrations about 32% lower than men who did not consume soy foods at all.

It's important to note the context of this finding as provided by the study: sperm concentration was well above normal even in the groups that ate the most soy. This suggests that while soy might be associated with lower relative concentration compared to non-consumers in this specific group, it did not necessarily drop below typical fertile ranges for these men.

Understanding the Findings

This single study suggests an inverse association between soy intake and sperm concentration within the observed population. It does not indicate that soy increases sperm count or quality.

Why the Association?

Soy contains phytoestrogens, compounds that have a structure similar to estrogen. There has been interest in how these compounds might affect hormone levels and reproductive health in men, although the overall impact is still a subject of ongoing research and debate.

In Summary

While research on the effects of soy on male fertility is not extensive and findings can vary, the specific study referenced indicates an association between higher soy intake and lower sperm concentration, rather than a boost. However, the study also highlighted that sperm counts remained within normal ranges even with higher soy consumption in the observed group.
