What is Ashwagandha?

Ashwagandha also called winter cherry or withania somnifera is an evergreen shrub with yellow flowers, grown in India, parts of North Africa and the Middle East [1]. It is one of the most central herbs in Ayurveda, an alternative form of traditional medicine centred around Indian principles of healing naturally [2]. Ashwagandha has been used for upwards of a thousand years to treat a range of ailments including stress, to improve concentration and increase energy levels [3]. The name refers to Sanskrit for ‘smell of the horse’, referring both to the plant’s scent and its potential ability to increase strength abilities. A huge range of benefits have been claimed for this plant, however this blog will focus on its proposed use to increase penis size.

Can Ashwangha increase penis size?

There is little evidence to suggest that Ashwangha can increase your penis size, despite what people aiming to sell it to you might claim. This claim may have sprung from research suggesting consuming Ashwagandha may be able to increase your testosterone levels. A study in 2019 noted a 14% increase in testosterone levels when compared to a placebo in a small sample of 43 men aged over 40 and overweight [4]. Further research in 2010, recorded a significant increase in testosterone in 150 infertile and fertile men. Interestingly it also increased the amount of luteinizing hormone, which is involved in stimulating the production of testosterone.

Other studies have however found no significant increases or even a decrease in some cases. Additionally, unfortunately, for those hoping for greater lengths a 2011 and 2014 study concluded it had little impact on penis size or erectile dysfunction rates [5],[6].

Are there any risks with taking Ashwagandha?

Ashwagandha has relatively few risks associated with it. One advantage of Ashwagandha is that it has been used for centuries meaning the possible side effects are relatively well understood [1]. These typically include drowsiness, gastrointestinal problems or diarrhoea, though many people report no side effects. Though people who are pregnant or taking any of: barbiturates, benzodiazepines or anticonvulsants, should not take ashwagandha. One important point is that it is not considered a medicine within the UK and therefore is not subject to as stringent checks as would normally be expected. This means you should apply caution when choosing a supplement as they may not have the correct ingredients as claimed or could have a lower purity than expected. For this reason, make sure you buy from a reputable such as a well-established high street pharmacy chain.

Are there any other benefits of taking Ashwagandha for sexual health?

While it cannot increase penis size, many other benefits such as improved athletic performance and reduced anxiety have been suggested. One research analysis that looked at 12 studies of people taking ashwagandha suggested that it may enhance strength and oxygen use during exertion [7]. Additionally, one study in 2015 on male participants taking 600 mg of ashwagandha a day and resistance training for 8 weeks had significantly increased both muscle strength and size when compared to a placebo [8]. Furthermore, although an appropriate dose is not clear yet the benefits of Ashwagandha for anxiety are well-established, which can be beneficial for your sexual health [8].!
