This is a difficult question to answer. Statistics will vary with each doctor according to his/her practice. Some doctors will work with all couples while others choose not to work with patients over a certain age or with certain medical conditions. This alone can skew statistics. It is best to work with a doctor with whom you feel comfortable and who is experienced with your particular infertility issues and third party reproduction. For surrogate arrangements, SSA will work with your referring doctor if he/she is willing to participate in a third party arrangement. If you are coming without a doctor referral, SSA can provide references to several IVF specialists with whom we have worked and have the utmost confidence.
