Key Topics to Revise

1

Types of Reproduction

  • Reproduction is the biological process by which organisms produce offspring of their own kind.
  • Asexual reproduction involves a single parent and does not involve the formation or fusion of gametes.
  • Binary fission, budding, and fragmentation are examples of asexual reproduction seen in lower organisms like bacteria, hydra, and planaria.
2

Human Male Reproductive System

  • The male reproductive system includes testes, epididymis, vas deferens, urethra, penis, and accessory glands (seminal vesicles, prostate gland, Cowper’s glands).
  • Testes produce sperm and secrete testosterone, the male sex hormone.
  • Sperm mature and are stored in the epididymis before being transported via the vas deferens.
3

Human Female Reproductive System

  • The female reproductive system consists of ovaries, fallopian tubes, uterus, vagina, and external genitalia.
  • Ovaries produce ova (eggs) and secrete estrogen and progesterone.
  • Each month, an ovum matures in a Graafian follicle and is released during ovulation.
4

Menstrual Cycle and Fertilization

  • The menstrual cycle is a monthly cycle (average 28 days) in females that prepares the body for pregnancy.
  • It begins with menstruation (days 1–4), where the endometrial lining is shed if no pregnancy occurs.
  • From day 5–13, follicular development occurs under the influence of FSH; estrogen levels rise.
