gonads and gametes? reproductive cells produced by gonads.
What are the male and female Male gametes: sperm; Female gametes: ova.
gametes?

characteristics typically develop? males).
What is spermatogenesis? The process of sperm production.

What is the timing and duration of Begins at puberty, continuous throughout life (~74
spermatogenesis? days per cycle).
What is the timing and duration of Begins before birth, arrests until puberty, then one
oogenesis? per month until menopause.

What is the role of LH in males? Stimulates interstitial (Leydig) cells to produce
testosterone.
What is the role of FSH in males? Stimulates sustentacular (Sertoli) cells to support
spermatogenesis.
