“…Furthermore, retractile testis was found to be 3.9% in our study. It is considered that the reason for the contradictory data regarding the frequency of retractile testis may be due to misdiagnosis of the disease and different retractile testis definitions amongst different investigators [8,[14][15][16] . On the other hand, the conditions of the examination area and the room temperature are both important factors to establish the correct diagnosis.…”

Objective: The aim of this study was to determine the prevalence of cryptorchidism, retractile testis and orchiopexy and investigate the effects of these clinical conditions on testicular volume among schoolchildren aged 7–12 years. Methods: It was a cross-sectional and descriptive study. The participants were stratified by school population and age and 1,800 questionnaires were distributed. The inguino-scrotal examinations and the testicular volumes of the children were recorded. Results: The parents of 1,500 children agreed to allow their children to be examined. The prevalence of cryptorchidism and orchiopexy was found to be 0.73 and 1.3%, respectively. Retractile testis was found in 3.9% of the children. The mean testicular volume of children having retractile testis (1.82 ± 1.41 ml) was less than the ones who do not (2.38 ± 1.40 ml, p < 0.05). The prevalence was 1.7%, and 4% in the participants who had inguinal hernia also had hernioplasty. Conclusions: The prevalence of cryptorchidism and the mean age of orchidopexy are high among schoolchildren aged 7–12. Retractile testis might have some negative effects on the development of testicular volume in children. Parents and healthcare and education professionals should give special attention to inguino-scrotal diseases.

“…The motor function of GFN can be measured by electrophysiologic evaluation of cremasteric reflex and GFN motor conduction studies [2,6]. Although chronic pain after hernia repair is said to be very rare and mild in childhood, it should be noted that clinical demonstration of nerve injury is not as easy as in adults.…”

“…10 Current knowledge of the physiological control of the CM is mainly restricted to the evaluation of the CM reflex. 2,20 One of the aims of this study was to investigate whether the CM could be elicited by the transcranial magnetic stimulation (TMS) of the motor cortex and to calculate its central motor conduction time. A second aim was to define a method for determining peripheral motor conduction time to the CM in normal men.…”

The few electrophysiologic studies of the cremasteric muscle (CM) have mainly been restricted to the cremaster reflex with no reference to central and peripheral nerve conduction to the muscle, probably for technical reasons.Twenty-six normal adult male volunteers were studied by transcranial magnetic cortical stimulation (TMS) and stimulation of thoracolumbar roots. The genitofemoral nerve (GFN) was stimulated electrically at the anterior superior iliac spine and a needle electrode was inserted into the CM for conduction studies. The motor latency to the CM from the cortical TMS ranged from 20 to 33 ms among the subjects (25.8 +/- 2.9 ms, mean +/- SD). Magnetic stimulation of the lumbar roots produced a motor response of the CM within 9.6 +/- 1.9 ms (range, 6-15). The central motor conduction time to the CM was 16.5 +/- 2.8 ms (range, 10-21). Stimulation of the GFN produced a compound muscle action potential with a mean value of 6.4 +/- 1.8 (range, 4-10) ms in 23 of the 26 cases. Thus, central motor nerve fibers to the CM motor neurons exist, and there may be a representation area for the CM in the cerebral cortex. The GFN motor conduction time to the CM may have clinical utility, such as in the evaluation of the groin pain due to surgical procedures in the lower abdomen.
