Michael, endocrinologic factors are the key players in all ejaculatory disorders - premature ejaculation = hyperthyroidism, delayed ejaculation (incl. refractory period) = hypothyroidism. POIS more looks like delayed ejaculation to my blind eye, but keep in mind hypo and hyper are not distinct and patients criss-cross between the two. Endocrinological factors, i.e. Thyroid affects every cell in our bodies, CNS, PNS, brain cells, body cells.
You can go to a Gynaecologist or Neurologist but they will only address a few out of many many symptoms. The key is ENDOCRINOLOGIST. Use this forum as talking points, but if you have access, you must go to some brave Endocrinologist (that doesn't believe every word taught by the medical power groups, and she/he will test you for Cortisol, T3, Total T3, Free T3, same thing with T4, Reverse T3, TSH, antibodies, etc). Michael218, your experience would be very helpful to us all here on this forum. A brave Endocrinologist will recognize the picture on the ground proven by research (better yet take a printout of that research) that says that thyroid hormones fluctuate drastically throughout the day so many patient are not getting diagnosis simply because of the time of the day their testing happened (as the current established ranges are political and not based on material evidence). Heck the blatant injustice to the sufferers is that 90% patients are not getting diagnosed simply because current medical guidelines given to doctors (and reimbursed by insurance) are only for TSH and T4 which are pathetically insufficient, leaving a vast majority untreated, and leaving them to various many disorders (un-necessary) of today, creating this big bloated messy medical system. I know guys my writing is tarty, but it is necessary for us to be rationally circumspect so we can recognize that every profession has this power/political system, and its not incidental that our medical system is so bloated and messy.
