origin, continuation of fibers from inferiormost internal oblique muscle and slips arising from the inguinal ligament; insertion, becomes interspersed within cremasteric fascia of spermatic cord and intermediate covering of testis; in the female, the round ligament of the uterus; action, elevate testicle; nerve supply, genital branch of genitofemoral.

cre·mas·ter mus·cle

(krē-mas'tĕr mŭs'ĕl) [TA]
Origin, from internal oblique muscle and inguinal ligament; insertion, cremasteric fascia (spermatic cord); action, raises testicle; nerve supply, genital branch of genitofemoral; in the male the muscle envelops the spermatic cord and testis; in the female, the round ligament of the uterus.

Retractile testis is considered as a normal variant, where the cause for retraction is an overactive cremasteric muscle. These patients require close follow-up.
The descending testicles move from the urogenital ridge to the inguinal region simultaneously with shortening of the gubernaculum, testicular differentiation, and development of the cremasteric muscle. The Leydig cell produced insulin-like hormone (Insl3 or descendin), which appears to mediate this transabdominal migration.
4 Your cremasteric muscle protects your testicles when you feel threatened by moving them closer to your body.
(8) The torsed structure in this condition is the spermatic cord, which contains the testicular artery, vas deferens, lymphatic vessels, sympathetic nerves, and cremasteric muscle. (5) Scrotal pain may be accompanied by nausea and vomiting (26%); abdominal pain (7%); it may awaken the patient from sleep (21%) or occur during times of increased activity (14%).8 The frequency with which intermittent episodes occur is becoming more well recognized.
The cremasteric muscle fibers around the internal ring are divided so that the internal oblique and transversalis muscle edges at this region are freed.
Retractile testes may be even more difficult to differentiate from undescended testis with the use of ultrasound due to factors, such as the cold gel temperature, pressure of the ultrasound probe pushing the testes towards the inguinal region, and concurrent stimulation of the cremasteric muscle. The routine use of ultrasound may increase anxiety and confusion in boys and their families.
Sometimes, while a primary care provider may believe that a testis is undescended, when an urologist examines the child, it may be discovered that it is simply "retractile." This means that the cremasteric muscles that surround the testis are pulling the testis up into the inguinal canal.
