1. Men

   • Key Hormone Players
     • Hypothalamus
       • Anterior Pituiatry
         • FSH
           • Stimulates
             • Needed for sperm formation
         • LH
           • Testis
             • Seminiferous Tubles
               • Sertoli Cells (nurse cells)
                 • Produces Inhibin
                   • Regulates sperm production
                     • Negative Feedback
                     • Sperm
                       • Meiosis
                         • N=46 diploid N=23 diploid Alleles are shuffled and # of chromosomes are halved
                         • 2n
                           • N
                             • N
                             • N
                           • N
                             • N
                             • N
               • Leydig Cells
                 • Situated in between tubles
                 • Produce Androgens
                   • Testosterone
                     • Regulates LH secreation
                       • Negative Feedback
                     • Sperm production
                     • Decreased levels = Andropause
           • Stimulates
       • Posterior Piuitary

2. Women

   • Key Hormone Players
     • Hypothalamus
       • Anterior Pituitary
         • FHS
           • Overies
             • ovarian follicle
               • Maturation of eggs
                 • Meiosis
                   • 2N
                     • N
                       • X
                       • X
                     • N
                       • X
                       • N
               • Produces estrogen
         • LH
           • Releases the egg
           • Forms Corpus Luteum
             • Produces estrogen
       • Posterior Pituitary
