• Parts of male reproductive system

  • Penis
  • Urethra
  • Testis
  • Scrotum
  • Bladder
  • Seminal Vesicle
  • Prostate Gland
  • Vas Deferens
• Male reproductive system

  Contains the external genitals and internal parts, including the prostate gland, vas deferens and urethra. A man's fertility and sexual traits depend on the normal functioning of the male reproductive system, as well as hormones released from the brain.
• Testes

  • Produces male gametes (sperm cell)
  • Releases male sex hormones, androgen and testosterones, which cause physical and physiological changes in males
• Scrotum

  • A sac which covers the testes and holds them outside the body. It protects the testes.
• Seminal Vesicles

  • Store sperms and secrete fluid into the sperm ducts. The fluid provides nutrients to the sperms and makes it easier for the sperm to move. It also prevents the sperms from sticking together.
• Prostate Gland

  • Secretes fluid into semen. The fluid activates the sperms.
• Hormones

  Organic chemical messengers produced and secreted by endocrine cells into bloodstream
• Sperm Ducts (Vas Deferens)

  • Carry sperms from the testes to the urethra.
• Functions of hormones

  Regulate, integrate and control a wide range of physiologic functions
• Urethra

  • A tube which carries urine from the urinary bladder and also carries sperms from the sperm ducts to outside of the body.
• Hormonal Disorders of Male and Female Reproductive System
• Penis

  • The organ from which semen (mixture of sperms and fluid) leaves the body and is deposited in the female reproductive system.
• Bulbourethral Glands

  • Produce the alkaline solution to neutralize the acidity of urethra.
• Parts of female reproductive system

  • Uterus
  • Fallopian Tube
  • Ovary
  • Cervix
  • Vagina
• Female reproductive system

  A sex organ system which the process of reproduction (offspring) occurs in a female body.
• Ovaries

  • Produce the hormones estrogen and progesterone. It is the site of ovum (egg cell) development and ovulation.
• Fallopian Tubes (Oviducts)

  • Carry the ovum from the ovary to the uterus. It is the site of fertilization.
• Fimbrae

  • It sweeps the ovum into the fallopian tube following ovulation.
• Uterus

  • Pear-shaped organ in which the embryo and fetus develop.
• Cervix

  • Separates the vagina from the uterus. It holds the fetus in place of pregnancy.
  • It dilates during birth to allow the fetus to leave the uterus.
• Vagina

  • Extends from the cervix to the external environment. It provides a passageway for sperm and menstrual flow.
