QUESTIONS ON FEMALE ANATOMY OR TOPIC??

• A human female typically has about 400,000
  follicles/potential eggs, all formed before
  birth.
• Only several hundred (about 480) of these eggs
  will actually ever be released during her
  reproductive years (Puberty Menopause)
• Normally, in humans, after the onset of puberty,
  due to the stimulation of follicular-stimulating-h
  ormone (FSH) one egg per cycle matures and is
  released from its ovary.
• Each Menstrual Cycle lasts 28 Days Each Cycle
  the Left Right ovary take turns and will
  release a potential egg
• (FREEZING EGGS?? COST)

FEMALE ANATOMY / CONCERNS

• Pre-Menstrual Syndrome Nervous tension, mood
  swings, headaches, bloating, and irritability
• Toxic Shock Syndrome Tampon Use (Rare)
• Puberty Sexual Maturity Ovaries release
  Mature Eggs
• Menopause Ovaries no longer release Mature Eggs
• ESTROGEN - FEMALE SEX HORMONE

QUESTIONS ON MALE ANATOMY OR TOPIC??

• For humans, entire process of spermatogenesis
  takes 74 days. Including the transport on ductal
  system, it takes 3 months. Testes produce 200 to
  300 million spermatozoa daily
• Prostate Health is of particular concern for
  Males after middle-aged years (45 )
• Mixture of Sperm Cells and other Fluids SEMEN

ANAL FACTS - RISKS

• Prevalence 5 to 10 of sexually active women
  engage in receptive anal intercourse This
  number is rising!
• For heterosexual couples, pregnancy can occur if
  semen is deposited near the opening to the
  vagina.
• Studies have suggested that anal exposure to HIV
  poses 30 times more risk for the receptive
  partner than vaginal exposure.

Anal Intercourse has Several Health Risks

• The anus lacks the natural lubrication the vagina
  produces - Penetration can tear the tissue inside
  the anus, allowing bacteria and viruses to enter
  the bloodstream more easily.
• The anus was designed to hold in feces. The anus
  is surrounded with a ring-like muscle, called the
  anal sphincter, which tightens after we defecate.
  Repetitive anal penetration may lead to weakening
  of the anal sphincter.
• The anus is full of bacteria. Even if both
  partners do not have a sexually-transmitted
  infection or disease, bacteria normally in the
  anus can potentially cause infections . Vaginal
  penetration after anal penetration can also lead
  to vaginal and urinary tract infections.
• Oral Contact with the anus can put both partners
  at risk for hepatitis, herpes, HPV, and other
  harmful infections.

The Beginning of the Life Cycle

• Hormones / Glands / Cells
• Gene is a section of a chromosome that
  determines or affects a characteristic or trait
• Chromosome tiny structures within cells that
  carry information about the characteristics you
  will inherit
• Hormone a chemical messenger produced by an
  endocrine gland
• Endocrine gland An organ that produces and
  releases chemical substance (hormones) directly
  into the bloodstream
• Hypothalamus Controls many of the Pituitary
  Gland Functions and controls the bodys water
  levels.
• Pituitary Gland pea-sized endocrine gland in the
  brain that controls growth, reproduction
  Metabolism

United We Stand Birth Control

• OVULATION EGG/OVULATION
• Fertilization- surface of the egg changes so no
  other sperm enter the egg
• FERTILIZATION

12
Developing Baby

• The Zygote - the united egg and sperm
  (Immediately after Fertilization through 36-48
  hours)
• Cell Division - from the two-cell stage until
  about nine weeks after fertilization it is called
  an EMBRYO (48 hours 9 Weeks)
• The Blastocyst (5 days after fertilization, the
  50-100 cell structure attaches to the uterus) - a
  sphere of cells surrounding a hollow center (PG.
  488-499)
• Implantation- the blastocyst attaches itself to
  the wall of the uterus, this process is called
  implantation.
• Ectopic Pregnancy (Tubal)
• Around 9 WEEKS UNTIL BIRTH the developing human
  is called a FETUS.

Weight gain during pregnancy is around 25-35
pounds.

• Amniotic fulid-4 lbs.
• Uterus- 2 lbs.
• Breasts-3 lbs.
• Increased fat-3-5 lbs.
• Lean body mass-2 lbs.
• Fetus 7-8 lbs.
• Other increased body fluids

25
STAGES of BIRTH

• Labor Delivery Afterbirth
• Postpartum period During the first six weeks
  after delivery many changes take place. (Hormone
  Imbalances and irregularities)PG. 500
• Miscarriage - an embryo or fetus dies in the
  first 20 weeks of pregnancy
• Premature Birth a live baby is delivered before
  the 37th week of pregnancy

26
The 3 Step Birth Process VIDEO

• Labor During this stage strong contractions of
  the uterus cause the cervix to dilate.
• Delivery of Baby Can take anywhere from ½ to
  over 2 hours
• Deliver of afterbirth Contractions of the
  uterus push out the placenta. PG 499

• Positional plagiocephaly is the medical term for
  the twisting or flattening of a baby's head. It
  is usually called flat head, and results
  primarily when the infant lies in one position
  for extended periods.

33
Cord-Blood Banking

• What are blood-forming stem cells? These are
  primitive (early) cells found primarily in the
  bone marrow that are capable of developing into
  the three types of mature blood cells present in
  our blood - red blood cells, white blood cells,
  and platelets. Cord-blood stem cells may also
  have the potential to give rise to other cell
  types in the body.
