“…Spermatogenesis, especially differentiation and maturation of spermatocytes and spermatids, is temperature dependent requiring a temperature of at least 1°C to 28°C below core body temperature [41,42]. This is supported by studies in humans that artificially brought testicles near or into the inguinal canal and induced high scrotal and consequently testicular temperatures near core body temperature [43][44][45][46]. Consequently, spermatogenesis was impaired and semen quality reduced.…”

Infertility is defined as inability to achieve conception in a period of one year in a couple, despite regular and adequate unprotected sexual intercourse. A male is said to be infertile if he is unable to impregnate his partner after one year of unprotected intercourse. It is an important medical and social problem in the world as regards 15% of couples are infertile and 40% are infertile because of male factor infertility. This review highlights the risk factors and some causes that are responsible for male infertility. The aim of this review is to generate information which could help in the evaluation of male infertility.

“…Azoospermia could be achieved in 33 of the men. Moeloek (1995) investigated the influence of an insulating polyester suspensory to be worn 24 h day −1 on semen quality in 10 normozoospermic volunteers. Sperm density was impaired in the mean to 13 × 10 6 ml −1 after 24 weeks of exposure.…”

Influence of genital heat stress on semen quality in humans

The concept that an elevation of testicular temperature results in impairment of spermatogenesis is widely accepted. Here, current knowledge concerning genital heat stress and its consequences in men is reviewed. Duration of sitting during work positively correlates with daytime scrotal temperatures and daytime scrotal temperature negatively correlates with semen quality. However, the assumed negative correlation between duration of sitting and semen quality could not be shown in the available studies. Fertility parameters of professional drivers with long periods of sitting in vehicles were impaired; however, for predominantly affected drivers of vans, trucks or industrial heavy machinery potential confounders have to be considered. Wearing tight fitting compared with loose-fitting underwear is associated with significantly higher scrotal temperatures. However, available observations suggesting a link between tight-fitting underwear or trousers and impaired semen quality are not convincing. Studies addressing professional exposure to high temperatures delivered conflicting results concerning fertility parameters. The postulated negative impact of sauna visits on semen quality is not sufficiently underlined by the available studies. Oligozoospermic men with a varicocele have significantly higher scrotal temperatures than normozoospermic men, and according to several studies varicocelectomy normalises scrotal temperatures. A further link has been reported between fever and deteriorated semen quality. Contraception via genital heat stress has been demonstrated using hot sitting baths or insulating suspensors. However, down-regulation of spermatogenesis is inconsistent and unsafe. On the other hand, scrotal and consecutively testicular cooling is able to improve semen quality.

“…First, testicles were brought artificially near or into the inguinal canal (30)(31)(32)(33)(34). Beside the increased scrotal temperature in such experimental settings the cool temperature nadirs are also attenuated.…”
