Our Donors

All donors are either Anonymous or Non-anonymous.  Sperm donors have Basic or Extended profiles, all Egg donors have Extended profiles.

Donors are selected and screened in accordance with applicable national and international rules as well as the internal policies applicable at Cryos at the time of acceptance. The selection criteria is comprised of a wide range of aspects in terms of age, risk behavior and medical history of the donor candidate.

After completing a comprehensive medical questionnaire, donor candidates participate in an interview with set questions aimed at rejecting candidates with risk behavior and symptoms of disease.

In addition to this, a thorough medical examination and psychological evaluation of the candidate is carried out by our internal health practitioner, and blood and urine samples are tested for a large number of hereditary and infectious diseases. Candidates with a family history of serious hereditary mental and physical diseases are rejected.

Registering to Participate in the Cryos Network

All clinics must register to become a cooperating clinic in the Cryos network for their patients to be able to order donor sperm and eggs from the Cryos website.  Cryos also offers the opportunity for select clinics to participate as a reference clinic for our donor egg bank. 

To get started, simply refer your patients to our website.  Here, your patient can view all donor profiles at no cost.  Once a donor has been selected, the patient will place an order to put the donor sperm or eggs in reservation, and will put your clinic information in the ship to address.  Our proprietary system then links the order with your clinic profile. 

Clinics sometimes prefer for patients to pay Cryos directly and the clinic bill for treatment services only.  Other clinics will include the cost of eggs from Cryos in their overall fees and their patients pay nothing to Cryos. Either way, we will work closely with your clinic to make it very easy for you and your patient to purchase donor eggs.  Cryos’ Client Service department is available to assist you with availability of donor eggs and straws.  On your clinics first order, a client service associate will contact you to complete the registration process.
