Repro

• Penis


  • The organ by which sperm is introduced into the female
  • Contains spongy tissue that becomes turgid and erect when filled with blood
• Corpus spongiosum

  The mass of spongy tissue which surrounds the urethra and involves in erection by allowing rushing of blood into it
• Male Reproductive Organs

  • External Genital Organs: Penis, Scrotum
  • Internal Genital Organs: Testis, Epididymis, Vas deferens, Accessory glands (Seminary glands, Prostate gland, Bulbourethral glands)
• Scrotum


  • A pouch of skin formed from the lower part of the abdominal wall
  • Keeps the testes at a temperature slightly cooler than body temperature
• Epididymis


  • Tightly coiled tubes against the testicles
  • Acts as a maturation and storage for sperm
• Corpus cavernosa

  One of a pair of sponge-like regions of erectile tissue which contains most of the blood in the penis during penile erection
• Urethra


  A tube within the penis that conveys semen out of the body during ejaculation
• Testis/Testes


  • The two-oval shaped male organs that produce sperm and hormone testosterone
  • Testosterone - the primary male sex hormone
• Vas Deferens

  A thin tube that starts from the epididymis to the urethra in the penis
• Reproduction and Development

  1. Biological process for an organism to have an ability of reproducing their own kind

  2. Important for the survival of living things

  3. Life would come to an end without the process of reproduction

  4. Essential in multiplying species of its own kind

  5. Ensures that species continues to produce for future generations
• Accessory Glands

  • Produce nourishing fluids for the sperms that enter the urethra
  • Include Seminal Vesicles, Prostate Gland, Bulbourethral gland
• Male Reproductive System


  • Consists of a number of sex organs that are a part of the human reproductive process
  • Produces, stores, and releases the male gametes, or sperm
  • Produce sex hormones – testosterone
• Female Reproductive System
• Seminal Vesicles


  • Sac-like structures attached to the vas deferens at one side of the bladder
  • Produce a sticky yellowish fluid that contains fructose
• Prostate Cancer
• Bulbourethral Gland (Cowper’s Gland)


  • Small glands located on the sides of the urethra just below the prostate gland
  • Produce a clear, slippery fluid that empties directly into the urethra
• Prostate Gland


  • Surrounds the ejaculatory ducts at the base of the urethra, just below the bladder
  • Responsible for making the production of semen, a liquid mixture of sperm cells, prostate fluid, and seminal vesicles
• Internal Female Anatomy

  • Vagina - A muscular canal that connects the cervix and the uterus
  • Cervix - The lower part of the uterus that separates the lower uterus and the vagina
  • Uterus - Located in the lower belly area between the hips
  • Ovaries - Small organs located on both sides of the pelvis
  • Fallopian tubes - Connect the ovaries to the uterus
  • Hymen - A thin tissue that sits at the vaginal opening
• Accessory Glands

  1. Bulbourethral Gland (Cowper’s Gland)

  2. 2 small glands located on the sides of the urethra just below the prostate gland

  3. These glands produce a clear, slippery fluid that empties directly into the urethra
• The female reproductive system is the body parts that help women or people assigned female at birth
• Internal Genital Organs

  • Fallopian tube
  • Fimbria
  • Ovary
  • Uterus
  • Cervix
  • Bladder and Urethra
  • Vagina
• Female Reproductive System

  • Produce sex hormones – estrogen and progesterone
  • Menstrual
  • Produce egg
  • Support and protect developing embryo
• External Female Anatomy

  • Mons pubis - The rounded, fleshy area on the front of the pelvic bone where pubic hair usually grows
  • Labia majora - The fleshy outer folds of protective skin located on each side of the vaginal opening
  • Labia minora - Skinfolds that are just inside the labia majora
  • Clitoris - Located at the top of the vulva
  • Urethral opening - The tube that carries urine from the bladder
  • Vaginal opening - Located between the urethra and the anus
• External Genital Organs

  • Mons pubis
  • Labia majora
  • Labia minora
  • Clitoris
  • Urethral opening
  • Vaginal opening
• IVF (In Vitro Fertilization) - Fertilize the egg outside the body and transfer the embryo to the mother's uterus. Also called test tube babies
• Intrauterine Device (IUD)
• Surrogacy - An arrangement in which a woman (the surrogate) agrees to carry and give birth to a child on behalf of another person or couple
• Ligation
• What is Asexual Reproduction?
• ASEXUAL AND SEXUAL REPRODUCTION
• External Fertilization takes place when the sperm and egg meet outside the female's body
• Asexual Reproduction involves only a single parent and no sex cells are involved
• Ligation


  A surgical procedure for sterilization
• In Vitro Fertilization

  Embryo is fertilized outside the mother's uterus. Also called test tube babies
• Sexual Reproduction involves two parents, one egg cell, and one sperm cell
• Intrauterine Device (IUD)

  A birth control device
• Life begins at fertilization
• Surrogacy


  Arrangement in which a woman (the surrogate) agrees to carry and give birth to a child on behalf of another person or couple
• Internal Fertilization takes place inside the female's body
• Oviparity: Animals that lay eggs with the development of the embryo outside the mother's body
