What Your Fertility Ultrasound Is Really Looking For

Monday, September 14, 2026Women's Health MelbourneView original

What can a fertility ultrasound actually tell you about your chances of becoming pregnant?


In this episode of Knocked Up, Dr Raelia Lew speaks with a specialist obstetric and gynaecological ultrasound doctor to uncover what expert fertility scans can reveal about your reproductive health.


They explore how ultrasounds can identify endometriosis, adenomyosis, blocked fallopian tubes, fibroids and other conditions that may affect fertility. They also explain the difference between a standard pelvic ultrasound and a specialist gynaecological scan, including why the person performing and interpreting your scan matters.


You’ll learn what an antral follicle count really measures, why a low egg count does not automatically mean infertility, and how flushing the fallopian tubes may improve the chance of spontaneous conception for some couples.


The conversation also covers what doctors look for during a six-week pregnancy scan, including the location of the pregnancy, the number of embryos and early signs of viability. Importantly, they explain why an inconclusive first scan does not necessarily mean that a pregnancy will be unsuccessful.


In this episode:

  • The difference between a general and specialist gynaecological ultrasound

  • How endometriosis can appear on an ultrasound
