How Testosterone Injections Made This Man’s Penis Grow Longer
A 34-year-old man from Pakistan hit up an endocrinology clinic with an unusual complaint: He had super-scarce facial, armpit, and pubic hair.
When the doctors examined him, they also found his penis was much smaller than average. When stretched—which clinicians often use to mimic erect length—the man’s penis measured around 5 centimetres, according to the case report in BMJ Case Reports. That falls under the micropenis category, meaning a penis length that’s 6.35 centimetres standard deviations below the average. (In a 2015 analysis of penis sizes of 15,000 men, that would be anything 8.4 centimetres less when stretched.)

Doctors also determined his testicular volume was very low, as were his testosterone levels. The cutoff for low T varies among labs, but anything below 300 nanograms per decilitre (ng/dL) is generally considered diagnostic for low testosterone. This guy’s measured just 55.99 ng/dL.
Other lab work revealed low levels of other reproductive hormones, like luteinising hormone and follicular stimulating hormone, too. An interview with the man uncovered that he wasn’t ejaculating, and was experiencing fewer morning erections.
The diagnosis? A relatively uncommon disorder called idiopathic hypogonadotropic hypogonadism—where the testes don’t produce enough male sex hormones. They determined he had the idiopathic kind, meaning there were no structural or functional abnormalities in his pituitary gland or hypothalamus responsible for it.
Low testosterone can cause low sex drive, weak or fewer erections, increase in body fat, lower energy, reduction in muscle mass, depression, and fatigue. The doctors suggested testosterone injections to get his levels up to normal. After nine months of testosterone therapy, his testicular volume doubled in size, his testosterone levels normalised, and his penis grew to the mean size for adults his age. (According to that 2015 study, the average stretched size is 13.2 centimetres.) He was able to discontinue therapy.
If you have signs of low testosterone, talk to your doctor about getting your levels checked. If they are low, you might be a candidate for testosterone therapy—and you should notice your symptoms improve. But it’s important to note, if your levels aren’t clinically low, it’s unlikely that upping your T will help.
