Chapter 15 : Sexual Reproduction, Development and Growth

What will you learn in this chapter
Biology
In this chapter, we will be learning about sexual reproduction, development, and growth. We will start by studying the reproductive system of humans, including the anatomy of the male and female reproductive systems. Next, we will explore gametogenesis, which is the process of gamete formation. We will learn about spermatogenesis in males and oogenesis in females, and understand why gametogenesis is necessary for reproduction. Moving on, we will delve into the menstrual cycle, analyzing the changes in hormone levels during menstruation, follicle development, thickening of the endometrium, ovulation, and corpus luteum formation. We will also discuss how these hormone changes relate to pregnancy and miscarriage. Finally, we will study the development of the human fetus, including the process of fertilization and the formation of zygotes. We will then sequence and explain the early development of an embryo, covering the two-celled embryo, morula, and blastocyst stages.
