Hi, thanks for using healthcare magic Infertility can be due to issues related to either partner , sometime both partners. Both you and your husband would need to be investigated.. Your husband would need a semen analysis. For yourself you would need to have different parts of the reproductive system checked. This means assessment of the uterus, tubes, ovarian function. This assessment would be done by a careful history and examination by your doctor followed by investigations. Irregular periods may indicate that there is any issue with the ovaries for example PCOS (polycystic ovarian syndrome which is a common cause for infertility). This would be diagnosed by blood tests looking for the levels of certain hormones and also an ultrasound. If this is the case, it is treated by lifestyle changes and medication. Other tests can be done to check the tubes. I hope this helps
