BACKGROUND Scrotal temperatures in men have been reported to be either similar on both sides or higher on the left than the right scrotum. [] Key Method In Experiment I, eight men have been submitted to four successive body positions for 15 min each, first naked then clothed. Experiment II involved 11 postal employees working in a standing position for 90 min continuously. Experiment III involved 11 bus drivers and a 90 min period of continuous driving.

This suggested value could be adopted a cooling device as clinical therapy for a heat stress patient to decrease testicular temperature affecting spermatogenesis.

The reported differences in paired testes size was confirmed, introducing a possible relationship with structural and functional asymmetry of normal testes, based on MTR.

Training surgeons with clickers and warm scrotum studies win Ig Nobel awards

This year’s Ig Nobel Prize for medical education was habits, well demonstrated by clicker training of surgeons, and the clicker approach to dog training works by rewarding desired behaviors with a clicking sound made by pressing a small handheld device.

The history and the progress of the experimental and clinical works of teams who addressed hormonal, chemical and thermal approaches to male contraception have led to a better comprehension of spermatogenesis that could be useful in fields other than male contraception: effects of toxic compounds, fertility preservation.

Factors of Infertility among the Males in Selected Hospitals of Dhaka City

Study results confirm that understanding about male reproductive function and the environmental factors that affect it is insufficient and provide education to infertile men by doctors in charge about potential risk factors that may affect fertility and not just provide treatment because simple changes in lifestyle can improve fertility.

Heat and Oxidative Stress in the Germ Line

Spermatogenesis is highly dependent on scrotal temperature. In the ­testis, germ cells but not somatic cells are vulnerable to heat stress. In response to heat stress, germ cells undergo apoptosis,

A transient protective effect of this histone modifier in primary spermatocytes against heat-stress, which may operate as a negative coregulator of p53 in maintenance of apoptotic balance during early phase after hyperthermal stress is underscore.

Influence of the type of undertrousers and physical activity on scrotal temperature.

It is suggested that wearing tight fitting undertrousers is associated with higher scrotal and consequently testicular temperatures than wearing loose fitting undertroughers or none.

Deep scrotal temperature and the effect on it of clothing, air temperature, activity, posture and paraplegia.

Paraplegic men in wheelchairs have deep scrotal temperatures averaging about 0.9 degrees C higher than normal sitting men, and those whose scrotAL temperatures are very high usually lack motile spermatozoa, so means of lowering paraplegic deep sc rotational temperatures can be designed.

Increase in scrotal temperature in car drivers.

Continuous monitoring of scrotal temperature in men driving a car for a prolonged period indicates a potential exposure of male reproductive function to lifestyle factors.

Diurnal variations in scrotal temperature of normal men and patients with varicocele before and after treatment.

The data support the view that varicocele-related damage to the testis results from a lack of adequate cooling, and that treatment does not normalize the temperature pattern.

The extensive information available from experiments on animals concerning the thermal monitoring provided by the scrotum is reviewed to provide a means to apply this knowledge to a better understanding of male infertility and possibly to speed the development of male methods of fertility regulation.

Scrotal asymmetry and handedness.

The is ambiguous in that it is sometimes assumed to be based on an embryological explanation, i.e. that theleft testis descends in advance of the or that the left spermatic cord is longer because of the association of the left testis with the more cranially situated left kidney.
