The cremaster muscle, originating from the lower fibers of the obliquus internus and transversalis muscles of the abdomen, runs along the spermatic cord and then spreads fanwise downward within the cremasteric fascia to envelop the testis and adnexa. The size of these muscle strands varies from 20 to 200 microns in the normal person. The response of the cremaster to stimuli is the same as that of any other striated muscle. It is lowered in atrophy and increased in hypertrophy.
I encountered a case of bilateral hypertrophy of the cremaster muscle with spasticity, causing painful contractions and thus disrupting the patient's daily work. These painful spasms finally became unbearable, and the patient was forced to seek relief through operation.
