For those new to fertility preservation (FP) or thinking of establishing a service, I’m writing
this from a laboratory point of view with the aim of providing food for thought and, with the
benefit of hindsight, highlighting pitfalls that may be encountered. Thanks to ISFP biennial
meetings, ASFP and a number of highly experienced groups, there are numerous hands-on
workshops available which can provide an introduction to handling and cryopreservation
methodology for ovarian tissue. To build on the knowledge gained from these, practice with
human ovarian tissue is obviously preferable but, in many situations only animal ovaries are
available, and my suggestion would be to use fresh sheep ovaries.
