A cystoscopy is a procedure to examine the bladder and urethra using a scope. While it can identify certain conditions related to these areas, such as infections or abnormalities in the urinary tract, it may not specifically detect fungal infections around your penis.

If you suspect you have a fungal infection on or near your penis, including conditions like thrush (yeast infection), balanitis (inflammation of the head of the penis), or jock itch caused by fungi, getting an evaluation from a healthcare provider would be advisable. They can perform appropriate tests for accurate diagnosis and recommend suitable treatment options based on their findings.

It's essential to address any concerns about potential fungal infections promptly with medical professionals for proper assessment and management tailored to your specific situation.
