04 – Human Reproduction, Gonads, and Puberty
Mark
In this episode of the MCAT Prep Pod Biology Review, we explore the human reproductive system, focusing on male and female reproductive anatomy, gametogenesis, hormonal control, and the stages of puberty. You’ll learn how sperm are produced and mature (spermatogenesis), how eggs develop and complete meiosis (oogenesis), and how the hypothalamic-pituitary-gonadal (HPG) axis regulates reproduction through hormones like GnRH, FSH, LH, estrogen, and testosterone.
We walk through the menstrual cycle, including the follicular phase, ovulation, and luteal phase, as well as how hormonal birth control and pregnancy alter this cycle. The episode also explains key MCAT topics such as sex determination (XX vs. XY), the role of the SRY gene, and the hormonal changes during puberty and menopause.
Key concepts include:
Reproductive anatomy (testes, ovaries, uterus, etc.)
SEVE(N) UP and HMAT mnemonics
Hormonal feedback loops and sex hormone function
Stages of spermatogenesis and oogenesis
Menstrual cycle regulation and hormonal fluctuations
hCG, corpus luteum, and early pregnancy
Puberty onset and endocrine changes in males and females
In this episode of the MCAT Prep Pod Biology Series, we break down the full process of cell division, including the cell cycle, mitosis, and meiosis. You’ll learn the key […]
