Syzygium aromaticum is a type of clove that is most commonly found growing in the southern part of Asia, especially India and Indonesia. Research has shown that certain cloves, used in moderation, can potentially increase the level of testosterone in the body. However, there are certain risks involved with taking too much of these type of boosting supplements as it has been shown to potentially cause damage to the testes and decrease testosterone production.
Unfortunately, most of the research that has been conducted on Syzygium aromaticum has been performed on laboratory mice and rats. Currently there have been no published research papers regarding Syzygium aromaticum tested on human subjects.
Syzygium aromaticum has commonly been used for centuries to promote positive sexual health in men. On average, during these types of treatments, men are given about 2 grams of cloves per day. From what we have gathered, the researchers testing this ingredient on various test subject mice relied on a method of providing a proportional amount of Syzygium aromaticum to the test subjects as adult human men would receive in certain, specific treatment options.
How Effective is ingredient at Boosting Testosterone Levels?
The main question that most men in their 30s, 40s, and even 50s would want to know whenever they are looking into a new testosterone boosting supplement is the ingredient’s effectiveness. If certain ingredients are not really effective at boosting testosterone levels or potentially increasing luteinizing hormones in the body, then they may not have a positive impact on increasing energy levels, stamina, and libido.
Syzygium aromaticum is just one more in a long list of potential ingredients that are used in a variety of testosterone boosting supplements. We were only able to gather two research studies conducted specifically focusing on Syzygium aromaticum and its impact on testosterone levels in the body. However, these two research studies were conducted on laboratory mice.
Let’s take a look at each of these in more detail.
In the first study that we looked at, conducted in 2012 at Shiraz U by Dehghani, Heshmatpour, et al., the researchers wanted to determine the toxic effects of water and alcoholic extract of Syzygium aromaticum on sperm quality, sex hormones, and reproductive tissues in male mice. Their main focal point wasn’t to determine whether it could increase testosterone levels but whether it had any impact on these other aspects.
They conducted their study on the number of male mice, providing 250, 500, and 1000 mg/kg per day of water and alcohol extract of Syzygium aromaticum. They did this for a period of 34 days.
The researchers found that there was a significant drop in testosterone levels for the test group mice, compared to the placebo group. They measured a 70% decrease in testosterone levels. They also noted a significant increase in estradiol (a form of estrogen). They also noted a significant decrease in sperm count.
There may be a toxicity issue with regard to Syzygium aromaticum, especially in higher dosages. However, it was not concluded in this particular research study and more information will need to be acquired recording the findings.

In the second study we found, researchers Mishra and Singh at the Reproductive Endocrinology Laboratory, Department of Zoology, Banaras Hindu University in India looked at safety issues regarding Syzygium aromaticum with respect to testicular function in mice. This research study was conducted in 2008 on Parkes strain mice.
The researchers provided a hexane extract of flower buds of Syzygium aromaticum in three different dosages to a variety of mice. Those dosages were: 15 mg, 30 mg, and 60 mg/kg of body weight. This experiment was conducted over a five week duration.
What is interesting to note in this research study was that the researchers found lower dosages to have a more positive impact on serum testosterone levels. In fact, the mice that received 15 mg of the extract actually showed a 28% increase in serum testosterone levels. It also increased the activities of Delta (5) 3 beta-HSD and 17 beta-HSD levels.
They also noted that higher dosages saw dramatic decreases in these same levels, including serum testosterone levels.
Taken as a whole, this research could indicate that Syzygium aromaticum may actually be beneficial in boosting testosterone levels, as long as the dosages are not too high. On the other hand, elevated dosages could pose a significant problem for not only testosterone levels but physical health and well-being for the individuals taking it.

While it would be nice to have found specific research studies conducted on human male subjects, there needs to be a lot more done to determine not only the safety of Syzygium aromaticum, but also its viability as a boat testosterone boosting supplement.
The second research study we looked at highlighted the fact that a lower dosage actually provided a significant increase in serum testosterone levels while higher dosages actually had the opposite effect.
We will continue to scour various medical journals for research on Syzygium aromaticum to determine whether it is safe and effective, and assuming so, at what dosages.
