Reproductive Systems
Lesson Objectives
Content Objective: Describe the menstrual cycle in terms of LH, FSH, Estrogen and Progestrone, the development of the uterine wall and the maturation of follicles.
Language Objective: Annotate diagrams of the male and female reproductive system to show names of structures and their functions

A gene on the Y chromosome causes embryonic gonads to develop as testes and secrete testosterone.
Testosterone causes pre-natal development of male genitalia and both sperm • production and development of male secondary sexual characteristics during puberty.

Application and Skills
The use of IVF of drugs to suspend the normal secretion of hormones, followed by the use of artificial doses of hormones to induce super-ovulation and establish a pregnancy
Annotate diagrams of the male and female reproductive system to show names of structures and their functions.
