Some believe that larger testicles may be linked to certain biological and behavioral traits
Some researchers suggest that testicle size could be linked to certain traits or biological factors in men.
It may sound strange at first, but several scientific studies have explored whether having larger or smaller testicles connects to aspects of reproduction, hormones, or behavior.
A popular science YouTube channel has examined the topic, explaining that things such as sperm count and even how attractive your voice sounds may relate to the size and appearance of your testes.
AsapSCIENCE, created by Mitchell Moffit and Gregory Brown, who met while studying biology at university, produces animated educational videos on science and technology topics. Their style focuses on breaking down research papers and theories in a clear and engaging way.
In one video, they turned their attention to testicle size. Their explanation draws on several published scientific studies that look at reproductive biology and evolutionary theory.
What is the average testicle size?
Healthline reports that the average size of a man’s testicles is about 4 x 3 x 2 centimeters.
If you have noticed that one testicle is slightly larger than the other, there is no need to panic. It is normal for one to be a bit bigger.
In many men, the right testicle tends to be slightly larger, while the left often hangs a little lower.
Bupa states that healthy testicles usually feel firm and smooth, but not hard to the touch.
Does testicle size mean anything?
The AsapSCIENCE hosts explain that scientists have observed differences in scrotum size between humans and other primates. They say this can be linked to two evolutionary ideas known as “pre-mating” and “post-mating.”
In some monkey species, “pre-mating” success relies on visible physical traits that signal dominance. “Post-mating” success, however, relates to sperm production, including both quantity and quality.
Research on howler monkeys found that those with the loudest, lowest-frequency calls tended to have smaller testicles.
When looking at humans, the creators mention a study suggesting that men with lower-pitched, more attractive voices had lower sperm counts.
In general, larger testes are associated with higher sperm production. Another study explored whether testicle size could connect to family behavior, raising questions about parenting styles.
Some findings suggested that men with larger testicles spent less time on childcare and family-focused activities. Those with smaller testicles were described as showing more nurturing behavior, although researchers stress that this link is not firmly proven.
This idea remains theoretical. It is not as widely discussed as the so-called “summer long balls” effect, which refers to how warmer weather can cause the scrotum to hang lower due to temperature regulation.

Does testicle size impact your health?
Medical News Today reports that testicle size does not directly determine overall health. However, testicular volume is linked to sperm count.
A 2022 study found that children and teenagers who were overweight or insulin resistant tended to have smaller testicles. This finding suggests there may be a connection between body weight and testicular development.
Rossella Cannarella, M.D., from the University of Catania in Italy, stated via the Endocrine Society: “More careful control of body weight in childhood and adolescence may help to maintain testicular function later in life.”
Testicle shrinkage can also result from a condition known as testicular atrophy, which may affect one or both testes. Symptoms can include reduced sex drive and infertility. Causes can range from aging and inflammation to steroid or estrogen use.
Testicular cancer can also change the size or shape of a testicle. Cancer Research UK notes that swelling, a lump, or one testicle becoming noticeably larger than the other can be warning signs.
If you notice any unusual changes, it is important to speak with a GP to have them checked.
