Can stress can play a roll of your infertility ?

Yes, but...: ...not in measurable or predictable ways. Stress is a higher brain and/or lizard brain (midbrain) function. That feeds into the hypothalamus, which talks to the pituitary gland, which regulates ovarian or testicular function, depending on gender. There are things you can do to alleviate stress. Get out of stressful circumstances, see a therapist, take medication for anxiety and/or depression.

No: It can effect your menstrual cycle timing but ultimately doesn't cause you to be infertile.
