Which imaging investigation is commonly used in the workup of female infertility?

Transvaginal pelvic ultrasound is a commonly used imaging investigation in the workup of female infertility because it provides valuable insights into the reproductive organs in a non-invasive manner. This imaging technique allows for detailed visualization of the uterus, ovaries, and surrounding structures, which is crucial in identifying any anatomical abnormalities, such as ovarian cysts, fibroids, or uterine abnormalities that could contribute to infertility.

Moreover, transvaginal pelvic ultrasound can assess ovarian reserve by visualizing the follicles and inform on conditions such as polycystic ovary syndrome (PCOS) or endometriosis, which are known to impact fertility. The ability to perform the procedure in an office setting, along with the lack of radiation exposure, further enhances its suitability for initial investigations in female infertility.

In contrast, other imaging modalities such as CT scans or MRI, while useful for various diagnostic purposes, are not typically the first line for evaluating infertility. A CT scan of the abdomen provides comprehensive information useful for certain abdominal or pelvic pathologies, but the radiation exposure and the less focused nature make it less ideal for evaluating the reproductive system specifically in the context of infertility. MRI offers excellent soft tissue contrast but is higher in cost, less available, and also less commonly used in
