I went to the endocrinologists because i thought i was developing gynocomastia, he ran a lot of hormones. my testosterone and prolactin were in the normal range. why did he not run estrogen? could that be causing the gynocomastia?

Well : Please rephrase your question you said you’re endocrinologist ran out of hormones ?? Ask your endocrinologist what specific tests he ran generally run a total and free testosterone the free testosterone is the functional portion. Prolactin checks for a prolactinoma I kind of benign growth that causes hormonal problems with excess prolactin hormone production
