Primary outcomes
We defined three primary outcomes for the current review:
I. Relative risk or odds ratio of EjD diagnosis among the studied subjects according to the presence of accompanying thyroid dysfunction.
II. Correlation measure and direction between serum TSH and IELT with or without PRO measures related to ejaculation in the subjects.
III. Proportional improvement in the IELT and/or PRO measures related to ejaculation of the subjects in studies investigating the quantitative effects of treatment for accompanying thyroid dysfunction.
