When boys reach puberty, their body changes significantly. It begins to increase the production of testosterone which is the quintessential male hormone that is responsible for body hair, increased strength and muscle mass, stamina, sexual characteristics, a deeper voice, and much more.
As they move into their later teen years and early 20s, testosterone production is at its peak. By the time a man reaches 25 years of age, production of testosterone begins to decline. Not only does it begin to decline, but the amount of free testosterone in the body also diminishes. It’s the free testosterone (the testosterone that not that is not bound to either SHBG (Sex Hormone Binding Globulin) or to the protein albumin) that is directly responsible for significant muscle gain, stamina, and performance, especially in athletic activities.
Most men don’t immediately see the effect of decreased testosterone in their body until they reach their mid to late 30s or 40s. At that point, it becomes obvious that they no longer have the same stamina, energy, or ability to gain muscle or even maintain the muscle that they have gained through the years.
Relying on testosterone boosting supplements can be a crucial component for many adult males to help them increase their sexual drive, keep the muscle they have built over the years, and exercise at high performance levels for as long as possible.
Introducing Hibiscus Rosa Sinensis
Hibiscus rosa sinensis is commonly referred to as Chinese Hibiscus. It can also be referred to as shoe flower or Hawaiian Hibiscus. It is a bushy, evergreen shrub that grows to about 8 to 16 feet tall and has shiny leaves and brilliant red flowers in the summer and fall months.
It is commonly used as an ornamental plant throughout the tropics and subtropics. It does not do well in temperatures below 50°F (10°C). The flowers of Hibiscus rosa sinensis are edible are commonly used in salads throughout the Pacific Islands. The flower is also commonly used in many hair care products and can be found in shoe shine materials throughout parts of India.
Through the ages it has developed numerous medical uses, especially in traditional Chinese medicine and herbology.
Does Hibiscus Rosa Sinensis Help Boost Testosterone Levels?
The main focus of this review is to determine whether Hibiscus rosa sinensis is actually effective at helping to boost testosterone levels in the body or increase the amount of free testosterone. Three research studies were found in various medical journals and other publications that were directly associated with testosterone and Hibiscus rosa sinensis.
All three of these studies were conducted on male rats, rather than human subjects. Many research studies conducted their testing on rats because of the close physiological connection to humans, but any results that are found to be potentially positive with regard to laboratory rats needs to be tempered because there may be differences when it relates to human subjects.
Let’s take a look at the three studies we found regarding Hibiscus rosa sinensis.
The first study we looked at was by Jana, Ray, et al. at the Dept. of Anatomy, North Bengal Medical College, in India. It was conducted in 2013. The researchers wanted to study the effects of Hibiscus rosa sinensis flower extract on the spermatogenesis of male albino rats.
It was not clear the size of the test subject group, but they were provided an aqueous extract of 150 or 300 mg/kg body weight. Different test subjects groups were provided these dosages for 30, 45, and 60 days.
The researchers found that the test subject rats experienced significant to mild damage to the testes, depending on the duration of the treatment. This is a significant finding with regard to safety of Hibiscus rosa sinensis for human subjects.

The second research study we found with regard to Hibiscus rosa sinensis and testosterone came from Nigeria and was conducted by Ekpenyong and Udoh at the Department of Zoology and Environmental Biology, Faculty of Science, University of Calabar, in Nigeria in 2008. These researchers wanted to determine whether Hibiscus rosa sinensis flower petals would have any significant impact on sex hormone profiles of male albino rats.
The rats were provided various dosages of an ethanol like extract of the petals. The dosages ranged from 150 mg/kg and 300 mg/kg for what was considered the high dose and 45.36 mg/kg per day as the low dose.
Researchers noted a marked increase in testosterone levels at the higher dosage but no real increase at the lower dosage. There was also noted a complete degeneration of spermatozoa in the lumen of the seminiferous tubules. In other words, these researchers also found potential damage caused by Hibiscus rosa sinensis to the testes or other male reproduction organs.
The researchers concluded that even though there was an increase in testosterone, there was damage to certain cells that ultimately caused reduced testosterone production for the test subject male rats.

In the third research study we found that studied Hibiscus rosa sinensis and its impact on testosterone levels was conducted in 2007 by Olaqbende-Dade, Ezeobika, and Duru at the Department of Pharmacognosy, Faculty of Pharmacy, College of Medicine, University of Lagos, in Nigeria. These researchers tested immature male rats and provided them equal dosages of aqueous and alcoholic extracts of Hibiscus rosa sinensis for eight weeks.
The researchers found an increase in the weight of the testes and other male reproductive organs based on the percentage of the dosage that increased with regard to body weight.
There was no direct note on the impact of Hibiscus rosa sinensis on testosterone levels, only that it increased the weight of the testes and other male organs.

Hibiscus rosa sinensis may have numerous benefits for boosting testosterone levels and other aphrodisiac qualities in traditional medicines, but based on the research studies we found that directly tested Hibiscus rosa sinensis with regard to testosterone production, there is some cause for concern with regard to safety of male reproductive organs.
It’s important to note that these studies were conducted were done on male rats rather than human subjects, which could have a significant impact on these findings. As more studies are found, we will update them accordingly.
