Females
Mesonephric ducts/ Wolffian ducts form most of the duct system in males or females
Males
If the ———–
(within testis-determining factor region of Y chromosome) is present, then proteins are made that stimulate production of androgen hormones and male phenotypic development ensues
Sex-determining region Y (SRY) gene
Chorion: Outermost membrane responsible for formation of the what?
Placenta
Pathway of sperm and pathway of urine

Where in the testis is sperm transported?
Vas deferens
Where is sperm produced in the testis?
Seminiferous tubules
Sertoli vs Leydig cells
Sertoli will always be inside seminiferous tubules. Leydig will be outside seminiferous tubules.
Where are sperm stored and allowed to mature before transportation through has different?

Interstitial/ leydig produce androgens/testosterone
Which cells in the testes assist in the production of sperm from germ cells, Interstitial or Sustentacular?
Sustentacular/ Sertoli cells assist in sperm production.
The prostatic, membranous, and spongy make up the three regions of what in the male reproductive system?
Urethra
In the male reproductive system the ductus deferens travel through what cord to reach the inguinal canal?
Spermatic Cord
A skin-covered sac that provides the testes with a cooler environment than body temperature.
