I just thought I'd comment on how I've noticed Clomid hurts my testicles. I noticed it too when I took HCG after my second cycle.
I started my Clomid after a moderately heavy 14 week cycle (at the usual recommended dosages). I was also running 20mgs a day of Nolva and had been doing so for a few weeks. After a couple of days I was aching in my nether regions. I thought it might have been my kidneys but then discounted that a few days later after making sure I drank enough water and cranberry juice to flush them. I decided to lay off the Clomid and Nolva and after a day the dull ache began to subside. The next day the ache had gone altogether.
Ok, I needed to run the Clomid and Nolva (for obvious reasons) so I started taking them again at 50mgs/20mgs. This went fine for a few days so I upped my dosage to 100mgs/20mgs again and low and behold the next day the ache returned.
I guess because my wee fellas have been out of action for so long they hurt a little when they are forced to start working again.
Any guys out there had similar problems? (If any girls had similar problems then you need to lay off the Test - lol.)
