What would happen if all regions of the
seminiferous tubules completed
spermatogenesis in synch with one another?
Spermatogenesis is organized into
Physiology and Anatomy
Looking forward .
Exam-1 (close book)
In males the surge center in
hypothalamus is destroyed.
Therefore, there are no surges

Male reproductive Anatomy
Male Reproductive System
The male reproductive system of mammals consists of
a. testes (testicles) in the scrotum
b. accessory organs including ducts and glands
Exocrine (produce spermatozoa/sperm)
Female Reproductive Anatomy
Basic functions of the female tract:
Produce viable oocytes
Maintain environment for growth and
development of fetus
Serve as copulation receptacle for penis
Produce hormones necessary for repro
Sexual Differentiation of the Brain
3. Sexual differentiation of the brain.
a. Testicular hormones
Testosterone from testis of fetus results in male behavior

During embryogenesis organs differentiate from discrete germ layers that make up the embryo
o Differentiation: is the process whereby a group os unspecialized cells develop into
recognizable groups of cells that have a comm
