  • Testes
    produce sperm and testosterone
  • Seminal vesical
    supply the sperm with nutrients
  • Prostate gland
    produces liquid which protects sperm
  • Couper's gland
    produces pre ejaculate to naturalize the acidity in the urethra
  • Ejaculatory duct
    contractions force semen through urethra
  • Seminiferous tubule
    contains germinal epithelium which produce sperm cells
  • Puberty
    the age at which sexual maturity is reached
  • Interstitial cell
    stimulating hormone - stimulates testosterone production
  • Spermiogenesis
    the process that produces sperm cells
  • Sertoli
    nurse developing sperm cells
  • Lumen
    where developed sperm cells are released into
  • Semen
    combination of sperm and the fluid from the three glands
  • Ovaries
    female gonad which produce female sexual hormones and help ova mature
  • Fimbriae
    finger like outgrowths which draw in the ova
  • Vulva
    external opening
  • Oogenesis
    the process where mature ova are produced by the ovary
  • Cilia
    the cells which push the ova along the falopian tube
  • Proliferative phase
    increase of thickness of endometrium
  • Secretory phase
    influenced by the progesterone the lining becomes vascular and edematous
  • Polycystic ovary syndrome
    hormonal disorder which causes infrequent or prolonged pregnancies
  • Fertilization
    the fusion of sperm cell with one egg cell which has been released by the ovary during ovulation
  • Chorion
    the outermost membrane of the embryo responsible for implantation, it also produces progesterone
  • Amnion
    a thin strong membrane that surrounds the embryo and produces amnionic fluid
  • Amnionic fluid
    cushions the fetus and regulates temperature, also lubricates birth canal during delivery
  • Allantois
    pouch like membrane which contributes to the formation of the umbilical cord
  • Umbilical chord
    forms an extension of the chorion, supplies nutrients and removes metabolic waste
  • Placenta
    the site of exchange of nutrients and gases between the fetus and the mother
  • Birth
    the expulsion of a fully developed fetus
  • Labor
    increase of estrogen, progesterone drops causing rhythmic contractions of the uterine wall
  • Dilation
    first stage of child birth whereby the fetus engages the cervix
  • Delivery
    strong contractions force the head of the fetus out, then the shoulders and rest of the fetus
  • Afterbirth
    contractions continue until the placenta and umbilical chord pass out of the vagina
  • Breast milk
    contains all nutrients in ideal proportions and valuable anti-bodies
  • Artificial insemination
    sperm is inserted into the vagina with a syringe
  • Gamete intra
    fallopian Transfer - sperm cells injected into fallopian tube
  • In vitro fertilization
    sperm mix with eggs in petri dish, then injected into the uterus
  • Intracytoplasmic sperm injection
    sperm injected directly into the egg
  • Stem cell research
    embryonic stem cells can be used to replace damaged cells in the body
  • Amniocentesis
    amnionic fluid is removed then discarded fetus cells are tested
