  • If you are infertile (due to male partner or female partner) and undergoing in-vitro fertilization, you may require egg freezing. This is commonly done if your male partner is unable to produce adequate/sufficient vital sperms when your ovulation takes place and your doctor retrieves mature ova for in vitro fertilization. This gives better possibility of conceiving.
  • Another reason of egg freezing is simply you wish to preserve your mature eggs for future use. This trend is gaining popularity these days and egg freezing can be done at affordable cost easily and many couples, individuals are opting for egg freezing. You preserve eggs at young age and use them when time is right for you to become pregnant.

For egg freezing sperms are not required. Sperms are required for embryo freezing or embryo preservation, where fertilized eggs are preserved instead of mature eggs. In egg freezing, you may have to take ovulation inducing drugs to produce multiple eggs to be retrieved for egg freezing. Otherwise only one egg is matured during ovulation and this may take long time and may be costly and time consuming.
