It's easy to understand why both women and men are asked for examinations when the diagnosis of infertility is established.

In conclusion, what we suggest for pre-pregnant women is avoid extra examinations like HSG before trying to have a baby but to do regular body checks.

It's highly advisable to take folic acid when you decide to be pregnant. Always relax without calculating ovulation days. Finally, if you have tried more than a year you'd better consult a doctor with your partner.
