Chapter 27, Problem 7TF
Summary Introduction
Introduction:
Testes are enclosed inside the scrotum, which hangs out to maintain a lower temperature for the sperm production than the inside body temperature. The testes should be in 1-8oC below the average body temperature which is of 37oC. Rise in testes’ temperature may lead to decrease in sperm production. To maintain such lower temperature, testes is surrounded by specialized veins that lowers the temperature for sperm development.

The ducts of testes are made up of which of the following structures?
Seminiferous tubules, ampulla of vas, rete testis, efferent ducts, ductus epididymis
Seminiferous tubules, straight tubules, rete testis, ejaculatory, ductus epididymis
Seminiferous tubules, straight tubules, vas deference, efferent ducts, ductus epididymis

Females secrete Follicle Stimulating Hormone to develop the dominant follicle in ovaries. Since males do not have ovaries, males use testoterone to stimulate leydig cells for spermtogenesis.

During an erection, the corpus spongiosum never becomes as engorged with blood (never gets as hard) as the corpora cavernosa. Why must this be the case?
Where does fertilization take place (if it takes place)?
