Summary
Endorectal magnetic resonance (MR) imaging offers detailed views of the male reproductive system to diagnose infertility causes. Familiarity with MR imaging findings aids in accurate diagnosis and treatment guidance for male infertility.
Area of Science:
- Radiology
- Urology
- Reproductive Medicine
Background:
- Male infertility presents diverse etiologies including congenital, acquired, infectious, and hormonal factors.
- Endorectal magnetic resonance (MR) imaging is a valuable tool for visualizing the male reproductive tract.
- Accurate diagnosis is crucial for effective treatment of male infertility.
Purpose of the Study:
- To highlight the utility of endorectal MR imaging in evaluating male infertility.
- To classify and describe various causes of male infertility visualized by MR imaging.
- To emphasize the importance of understanding MR imaging findings for diagnostic accuracy.
Main Methods:
- Utilized endorectal MR imaging to obtain high-resolution, multiplanar images of the prostate and ejaculatory apparatus.
- Reviewed and classified causes of male infertility, including Wolffian and Müllerian duct abnormalities, acquired cysts, infectious prostatitis, and hormonal imbalances.
- Correlated imaging findings with known causes of infertility.
Main Results:
- Endorectal MR imaging provides detailed anatomical mapping of the reproductive tract.
- Identified various congenital (Wolffian/Müllerian duct abnormalities) and acquired (cysts, prostatitis) causes of infertility.
- Demonstrated that infectious prostatitis can mimic malignancy on MR imaging, and hormonal factors like low testosterone contribute to infertility.
Conclusions:
- Endorectal MR imaging is effective in diagnosing the causes of male infertility.
- Familiarity with normal and abnormal MR imaging findings is essential to avoid interpretation pitfalls.
- MR imaging aids in guiding appropriate treatment strategies for male infertility.
