The word "temporarily" is right in the title of the paper. The conlusion states "Systemic immune response after BNT162b2 vaccine is a reasonable cause for transient semen concentration and TMC decline. Long-term prognosis remains good."
Another word for 'transient' is 'temporary'.
OP doesn't mention that the effect is temporary. They're just going for the scare factor.
