• Freezing Eggs vs. Freezing Embryos The Pros and
  Cons

2

• Egg Freezing

• Egg freezing, also known as oocyte
  cryopreservation, is a process in which a woman's
  eggs are retrieved from her ovaries, frozen, and
  stored for later use. When a woman is ready to
  get pregnant, the frozen eggs can be thawed and
  fertilized with sperm, and the resulting embryos
  can be implanted in her uterus.
• Egg Freezing Process
• Hormone injections to stimulate ovaries for 8-10
  days.
• Egg extraction through transvaginal ultrasound
  aspiration (15-20 minutes).
• Freezing methods slow freezing (gradual
  temperature reduction) and vitrification (rapid
  freezing).

• Embryo Freezing

• Embryo freezing is a process in which fertilized
  eggs, known as embryos, are frozen and stored for
  later use. Embryo freezing can be done with IVF
  embryos, which are created in a laboratory, or
  with embryos that were created naturally and then
  frozen.
• Embryo Freezing Process
• Similar to egg freezing but involves exposing
  eggs to sperm for fertilization.
• Fertilized eggs develop into embryos, which are
  frozen using slow freezing or vitrification.
• Storage in liquid nitrogen for future use.

• Advantages of Freezing Eggs

• Can be done at any age
• Does not require a partner
• Offers more flexibility for future family
  planning
• Independent fertility preservation without
  fertilization.
• Potential ethical considerations are less
  complex.
• Can be used to protect fertility in women with
  medical conditions
• Increases chances of a successful pregnancy

5

• Disadvantages of Freezing Eggs

• Lower success rate than embryo freezing
• The cost of egg freezing can range from several
  thousand dollars to tens of thousands, depending
  on the clinic, number of eggs frozen, and storage
  duration.
• The success rate of egg freezing is not
  guaranteed, as not all frozen eggs survive the
  freezing and thawing process

6

• Advantages of Freezing Embryos

• Higher success rate than egg freezing
• Can be done with IVF embryos or naturally created
  embryos
• Allows for preimplantation genetic testing (PGT)
• Reduces the Need for Multiple Egg Retrievals
• Reduced risk of multiple births
• Flexibility in family planning
• Preservation of fertility

7

• Disadvantages of Freezing Embryos

• Requires a partner
• More expensive than egg freezing
• Not all embryos will survive the freezing and
  thawing process
• Damage to embryos during freezing and thawing
• Embryo freezing is a relatively expensive
  procedure

8

• Success Rates

• Frozen embryos
• The survival rate of frozen embryos is about 95.
• The live birth rate per embryo transferred is
  about 50.
• The overall live birth rate per embryo freezing
  cycle is about 60.

• Frozen eggs
• The survival rate of frozen eggs is about 90.
• The live birth rate per egg thawed is about 25.
• The overall live birth rate per egg freezing
  cycle is about 40.
