New images of Elon Musk once again sparked comments about his physical appearance, but this time a comparison steered the conversation toward his hormones.
On social media, people began sharing a photo of Musk alongside an image of a man who suffered from a rare estrogen deficiency, pointing out the resemblance between their body types. The medical condition involves a disorder that affects estrogen production and can cause significant changes in physical development.


That comparison prompted a comment that quickly drew attention: “He has taken so much testosterone that it has caused him an estrogen deficiency”.
However, there is one crucial detail: there is no public evidence that Musk is taking testosterone or has an estrogen deficiency. The comment is internet speculation, not a medical diagnosis.


The theory likely gained traction because of Musk’s own public comments about testosterone. In 2024, for example, he reacted positively to a post about men with “low testosterone”, which was examined by The Guardian. That, however, does not mean he is using testosterone.
So, while the comparison may be visually striking, the resemblance does not reveal what is actually happening with Musk’s hormones or health.
