The Reproduction and Development block in year 1 of the core curriculum will cover the normal development, gross and micro anatomy, physiology, function, and clinical assessment of the reproductive system. Emphasis is placed on how structure lends to reproductive function, mechanisms of sexual development, the reproductive endocrine axis, reproductive cyclicity, sexual behavior, genetics, the processes of fertilization through parturition, and lactation. Blocks will use a combination of lectures, laboratories, group assignments, seminars, and out of class projects to teach and reinforce the information. Case examples will be used to help the students better understand, research, integrate and think about the concepts taught in the classroom and laboratory.
