If you are not pregnant after 1 year of normal pregnancy preparation, you need to check the causes and treat the symptoms. You can have a tubal lavage or imaging to detect the condition of the tubes, and if there are adhesions and blockages, you need to have a laparoscopy combined with a guide wire to unblock the tubes, or you can do IVF directly. If there are no problems with the tubes, the ovaries should be monitored regularly for ovulation and the endometrium should be checked for adhesions. If there is no problem with ovulation and there are adhesions in the endometrium, hysteroscopy is needed to separate the adhesions in order to facilitate pregnancy.
