Q

Cells of Leydig/interstitial cells

A

produce testosterone in the presence of LH (luteinizing hormone)

Corpus cavernosum

A

sponge-like region of erectile tissue

12
Q

Corpus spongiosum

A

a mass of erectile tissue

Q

FSH

A

Follicle Stimulating Hormone; stimulates primary spermatocytes to undergo the first division of meiosis and helps with growth/development
