If the HSG suggests that there is an abnormality of the inside of the womb, a hysteroscopy can be done for a closer look. A fine telescope is passed through the cervix and the uterine cavity visualised. Hysteroscopy can detect fibroids or congenital variations such as a double-womb, bicornuate (heart-shaped) uterus or a uterine septum.

Thyroid Function Tests and Prolactin

 If a woman has irregular or infrequent menstrual cycles, or shows other signs of thyroid disease then it is important to exclude this.

Prolactin is a hormone that is normally involved in the production of breast milk and is released from a gland in the brain called the pituitary. An overactive pituitary gland can cause abnormally high levels of prolactin (hyperprolactinaemia) which prevents ovulation.

A blood test for prolactin levels should be done if cycles are infrequent or there is an unusual discharge from the breast.
