PLEASE RESPOND NEED ADVICE !

So i am going in for my yearly physical soon an i plan to ask for test to find out if im fertile or not(there is a few people in my family who can not have kids due to infertility) i have massive anxiety with doctors ever since i was i little i dont go unless i have too, but i was wondering if anyone had an idea on what kind of test/what do they do to check that kind of thing? My anxiety is hugely based on them going nere my private areas. Thats why im asking what kind of test are they an what do they do so i can prepare myself.
