Definitions

  • the invention pertains to improvement of semen quality. It relates, in particular, to a device, system and method for cooling testicles, in particular human testicles.
  • spermatogenesis A development of Spermatozoa in the human body, biologically referred to as Spermatogenesis, is a complex but well examined process. Physiology and pathology of spermatogenesis shall be briefly discussed in what follows with focus on the influence of scrotal temperature on spermatogenesis. The complete process and a precise description of other influencing factors besides temperature can be looked up elsewhere.
  • Spermatogenesis takes place in testes and epididymis which both are localized in the scrotum.
  • Spermatogonia develop from spermatogonial stem cells until puberty. After puberty, in adult testes, spermatogenesis starts by transformation of spermatogonia to spermatozoa in multiple and complex steps. It endures approximately 3 months Including the transport on ductal system to epididymis where adult spermatozoa are stored until ejaculation and gain motility and become capable of fertilization.
  • Spermatogenesis physiologically continues uninterrupted until death.
  • Intrascrotal temperature is physiologically approximately 2°C lower compared to body temperature and essential for optimal spermatogenesis. This is achieved by the mentioned extracorporeal location of testes and epididymis in the scrotum and a thermal exchange between warm testicular and epididymal arterial and cold venous blood streams, in particular by means of a countercurrent principle. So, the countercurrent principle is functionating as a physiological cooling system.
  • Mieusset et al. 1987 examined the association of scrotal hyperthermia with impaired spermatogenesis in 150 infertile men. As a control group they used 37 fertile men. They found for the group of infertile men approximately O.5°C higher scrotal temperatures compared to the group of fertile men.
