how long you been back on the nhs for treatment? (btw get a exemption cert you should get all treatment free as its for life)

you should be getting regular lvl checks and adjustment to your levo, to me 200mg sounds too low considering you have no gland.
personnaly i find the levo just right but still have the odd slow day where everything is a real effort but then i figure we all have them regardless

regarding the iodine treatment the only thing in your body that uses iodine is the thyroid gland i was told nothing about it affecting the sperm when i was treated and i think i still have some swimmers left
