For some women, chronic stress can affect ovulation by altering the signals to the part of the brain which regulate the hormones that cause the ovaries to release the egg. Research seems to confirm that there is a definite link between stress, anxiety, depression and infertility. When you are stressed out, you are probably not having sex as often as you should be – especially if you are trying to fall pregnant.
This means that you could miss critical fertility-window times, making conception even more difficult.
