Testicular size isn’t mentioned in that paper, only compensated hypogonadism, i.e. normal testosterone levels maintained through a higher drive from the pituitary gland.
The paper also mentions a link between acetaminophen (not ibuprofen) and longer time to pregnancy.
Chronic use of NSAID among which ibuprofen can ruin your stomach, and/or your cartilage.
Regardless, we are slowly getting out of the dark ages of psychiatry, whose models were until recently as worthy as humor or miasma theory. That’s great.
