The history

• The first pregnancy achieved through in vitro
  human fertilization of a human oocyte was
  reported in The Lancet in 1973.
• it lasted only a few days and would today be
  called a biochemical pregnancy.
• Today most IVF of a human oocyte is because most
  couples find it difficult to have their own
  children at an older age.

The Method
4
Ovarian cycle and Egg removal

• Treatment cycles usually begin on the first day
  of menstruation. This is where about 10 to 30
  eggs are removed while the patient is under
  conscious sedation or general anesthesia.

5
Fertilization

• After the Egg is removed it is prepared for
  fertilization. While this is happening the sperm
  is also being prepared for treatment before
  frozen and quarantined.
• The egg and the sperm are usually frozen together
  at a ratio of approximately 75000 sperm1 egg,
  where it is frozen for about 18 hours while
  fertilization takes place.

6
Selection

• In general the chosen embryo is selected by
  choosing which ones have reached the 6th 8th
  stage cell stage. However, this is not the case
  for most cultures.

7
Embryo transfer

• The embryos are transferred by a thin, plastic
  catheter, this goes through the vagina and the
  cervix.
• The number of embryos transferred is based on the
  evenness of growth and degree of fermentation.
  This is also judged by the age of the patient and
  other health traits she may have. Again this
  varies for different cultures.

8
Ethical and religous Issues

• There is a lot of ethical controversy over IVF.
  One of the biggest controversial things is
  laboratory mix ups. This is when laboratories mix
  up sperm samples or transfer of the wrong embryo.
  
• There is even more religious controversy over the
  fact that discarded embryos often result in there
  death.

9
complications

• Multiple births can be the result of in vitro
  Fertilization.
• Birth defects can also be results of in vitro
  fertilization.

10
Coping with IVF

• Due to the emotional and financial aspects of
  infertility treatment, many feel isolated and
  sometimes become depressed
