NOTE

HUMAN REPRODUCTION

Reproduction is the biological process by which organisms produce offspring or new individuals of the same species. It ensures the continuation of a species over generations. Reproduction can occur through two main methods:

  1. Sexual Reproduction: Sexual reproduction involves the fusion of specialized reproductive cells (gametes) from two parent organisms to form a new individual. In most animals, including humans, sexual reproduction typically involves the fusion of a male gamete (sperm) with a female gamete (egg or ovum) to form a fertilized egg (zygote).
  2. Asexual Reproduction: Asexual reproduction involves the production of offspring from a single parent organism without the fusion of gametes. This can occur through various mechanisms such as binary fission, budding, fragmentation, or the production of spores.

Structure and function of male reproductive system

The male reproductive system consists of several organs and structures that work together to produce, store, and deliver sperm, as well as produce and secrete hormones responsible for male sexual characteristics.

  1. Testes (Testicles): The testes are paired, oval-shaped organs located within the scrotum (a sac of skin and muscle) outside the body cavity. The testes produce sperm cells through a process called spermatogenesis.
  2. Epididymis: The epididymis is a coiled tube located on the back of each testicle. It serves as a site for the maturation and storage of sperm cells.
  3. Vas Deferens: The vas deferens is a muscular tube that carries mature sperm from the epididymis to the urethra. It serves as a passageway for sperm during ejaculation, transporting them from the epididymis to the ejaculatory duct.
  4. Seminal Vesicles: The seminal vesicles are paired glands located behind the bladder. They secrete a fluid rich in fructose, prostaglandins, and other substances that nourish and support sperm, forming the majority of semen volume.
  5. Prostate Gland: The prostate gland is a walnut-sized gland located below the bladder and surrounding the urethra. It secretes a milky fluid that helps activate and protect sperm, contributing to semen volume.
