How long does it take for tests results to come back, when you do initial tests for infertility?

Quickly. Some blood tests take 2-3 days. Some come back the same day. A semen analysis usually takes 1 day. I perform my own x rays so I have the results immediately. Some genetic tests may take a little longer. Overall, it takes about 3 weeks to run and get all tests results back because some are timed to different parts of the menstrual cycle.
