The researchers say there is a similar theme in men using medication to prevent male pattern baldness.
The drug finasteride changes the way testosterone is metabolised in the body and can limit hair loss, but side effects can include erectile dysfunction and a hit to fertility.
Prof Pacey told the BBC: “I would say more anabolic steroid users are likely to become sterile than you would think - 90% probably.” “Baldness is a bit more hit-and-miss, but sales are going through the roof and that makes it an increasingly common problem.”

This story was just now on BBC radio 2, although pinned on steroids and fin wasn’t mentioned.
EDIT - story just ran again with 11am news, which is good. Mentioned this time was “some hairloss medications” and “some anti-baldness medication” as causing ED.
