Basically there are factors which you have control over as regards your fertility and ones that unfortunately, you don’t.
Contrary to what people think stress does not cause infertility but being anxious or stressed can affect your monthly cycle (women) which impacts upon your chances of conceiving.
Being told to relax or ‘let nature takes it course’ is the last thing you want to hear even though it is well intentioned. If you have been having unprotected sex for a year but with no success then visit your GP.
