Cremaster m.

musculus cremaster controls superior and inferior movement of the scrotum. The purpose of this movement is to regulate temperature and also promote spermatogenesis ( sperm meaning sperm, ato being filler to join genesis meaning the beginning or origin of). Cremaster originates at the inguinal ligament and is innervated by the cremasteric artery and the genital branch of the genitofemoral nerve.

If i had a cremaster muscle, i'd definitely like to expose it to some chosen professors as a gesture of appreciation for their misunderstanding and lack of communication that has helped us as students, so much along the way.
