Male Reproduction 1) Diagram or explain the hypothalamic-pituitary gonadal axis in males- include cell types and all hormones involved and 2) what give two roles testosterone plays in regulating spermatogenesis. 1) Explain or diagram the process of spermatogenesis (Not the cycle or wave and use proper terms) starting with A0 spermatogonia to spermatozoa. 2) A young apparent heathy male enters the IVF clinic because of poor fertility for a sperm count and morphology exam. Results show that both count, and morphology were well outside of the normal range.
