GENERAL HISTOLOGY

Detailed explanation-1: -The epididymis (pronounced: ep-uh-DID-uh-miss) and the testicles hang in a pouch-like structure outside the pelvis called the scrotum. This bag of skin helps to regulate the temperature of testicles, which need to be kept cooler than body temperature to produce sperm.

Detailed explanation-2: -5.6∘C lower than body temperature.

Detailed explanation-3: -The scrotum is a male reproductive structure located under the penis. It has the shape of a sac and divides into two compartments. The structures contained in this sac include external spermatic fascia, testes, epididymis, and spermatic cord.

Detailed explanation-4: -Functionally, the dartos plays an important role in scrotal thermoregulation and therefore in the maintenance of the optimal temperature for spermatogenesis (about 2–3°C below body temperature; Tyrrell et al., 1942; Shafik, 1973; Spira, 1991).
