Alternatives to Freezing

Alternatives to Freezing

If for some reason you and your doctor decide that egg freezing is not right for you, then you might consider other options.



With modern vitrification techniques, both eggs and embryos can be frozen and thawed with equal success in our lab, but there are pros and cons of each approach.

Frozen Embryos vs Frozen Eggs pros and cons

Pros for frozen eggs

  • You do not have to commit your eggs to being fertilized with any sperm
  • You have full ownership of your eggs
  • You may choose when you want to use them

If you have a partner that you intend to have a family with at a later time, you may choose to freeze embryos instead of your eggs. Embryos are fertilized eggs that have developed for 3 to 5 days.

Pros for frozen embryos

  • You know how many viable embryos you would have frozen for a round of  IVF
  • You may consider genetic testing of embryos to disclose the proportion of embryos that were viable for use at a transfer
  • You have the opportunity to consider more treatment cycles at an earlier stage to obtain more viable embryos
  • You share ownership with your partner

Neither option promises a guarantee of success, as we are limited primarily by the number of eggs /embryos we have.


Donor Eggs

If you are unable to conceive using you own eggs, you may consider the option of using donor eggs. The use of donor eggs has become much more common, particularly with women over 40. This procedure has a very high success rate and it gives many women the ability to carry and deliver a child when they otherwise would have been unable to do so.

There are three ways that you can obtain donated eggs:

  1. Through a known egg donor. This is someone you know, like a friend or family member, who is under 35 years of age and is healthy.
  2. Anonymous frozen donor eggs that can be imported to Olive from the USA. Olive imports from Donor Egg Bank USA, one of the world's largest and most successful donor egg banks.
  3. Fresh anonymous donor eggs can be obtained by travelling to the USA or other countries.

Donor egg treatment is very successful. Depending on the age of the donor, the success rate is from 50%-80%.

Donor sperm

Donor sperm involves using sperm from an anonymous or known sperm donor to fertilize your eggs.

When to consider donor sperm

Donor sperm may be used by:

  • Single women
  • Lesbians
  • Women whose male partner does not have sperm
  • Women whose male partner has a hereditary disease

Where does donor sperm come from?

Donor sperm can be from someone you know or from an anonymous donor through a sperm bank. Most women use anonymous donor sperm.

Sperm donors are extensively screened for infectious disease, medical problems, psychological problems, and diseases that can run in families (e.g. genetic disorders).

Sperm banks provide information on the sperm donor's race, height, weight, personal history, academic performance, and many other demographic details. Also, depending on your preference, you may choose to see photos of the donor and read an essay they have written about themselves.
