Spices of natural origin may be precious complement of diet as they contain many biologically active substances which positively influence the functioning of human body. Such compounds are usually antioxidant and anti-inflammatory, and even sometimes anti-microbes. However, it occurs, that the compounds of some spices also show other interesting properties – they may influence e.g. the production of hormones, such as luteotropin and testosterone!
Spices have not only culinary, but also pro-health advantages. This fact was confirmed in many kinds of studies. The most often checked and promising spices are definitely ginger and curcuma. What's interesting, these spices – especially ginger – have an interesting potential when it comes to the secretion of gonadotropins and sex hormones, most of all – testosterone. The most important is the fact that the mentioned action is confirmed by the results of experiments done on cell cultures and animals, and also on humans! The truth is, there is a lot of data from researches done on rodents which show that both spices increase the production of testosterone. The problem is, that the trials done on animals don't have to have the same results on humans. Such situation is in case of e.g. plants, such as tribulus terrestris, which positively influences the production of androgens among rats, but is not that efficient for men. Is the situation with ginger and curcuma the same? Well, so far, there aren't any studies with the use of the latter spice, but ginger has confirmed its pro-testosterone potential in research done on people!
The scientists: Waleed Abid Al-Kadir Mares and Wisam S. Najam from the Tirkit University did an experiment on 75 married men at the age of 19 to 40 with fertility disorders. During the test, the volunteers were given ginger for three months. Unfortunately, the authors didn't reveal the dose they used, or the quality and form of the product. You can only guess, on the basis of literature, that the dose was probably between 50 – 100 mg per 1 kg of body mass. Nevertheless, the results of this experiment were very interesting. It was observed that:
eating ginger significantly improves the quality of sperm – the mobility of sperm increased (47.3%), and its amount was bigger (40.7%),
the supplementation with ginger significantly increased the level of LH (43.2%) and testosterone (17.7%)!
consuming the mentioned spice also contributed to the increase of the level of glutathione (antioxidant) and decrease of the amount of malonodialdehyde (the biomarker of oxidant stress).
Nowadays, you can say that, despite many studies done on cell cultures and animals, there are also data from the experiment done on humans, which confirms that ginger may positively influence the production of testosterone among men. The mentioned research has some limits, however, it's quite intriguing because of the fact that the result is a precedent. Therefore, it should be admitted that adding ginger to the meals is much better justified when it comes to the influence on testosterone production, than the intake of many popular pro-testosterone supplements.
