SEMEN CRYOPRESERVATION: PATIENT INFORMATION
SUCCESS RATE WITH FROZEN SEMENFuture reproductive options for the use of cryopreserved sperm include intrauterine insemination (IUI) or in vitro fertilization (IVF). The average conception rate for the first option, IUI, is 4-10% per cycle. With samples exhibiting lower than average fresh semen parameters, the conception rate may be lower. The latter option, IVF, would be reserved for situations where the initial sperm parameters are less than ideal, where the freeze/thaw process results in poor sperm characteristics (as determined by the test thaw), or where very few frozen sperm samples are available. In general, IVF with cryopreserved semen does not per se reduce the success rate of IVF. We recommend that patients discuss the optimal use of their frozen samples with a specialist in reproductive medicine at the appropriate time in order to maximize their chances for achieving a pregnancy. Problems such as miscarriage, implantation in the fallopian tube, and birth defects are possible in any pregnancy. There is no increased risk of any of these problems associated with the use of cryopreserved semen.THE SEMEN CRYOPRESERVATION PROCESSVariability in the success of the freezing process occurs between individuals as well as between semen samples. For each semen sample we determine the semen volume, sperm count (concentration), and percent motility. The sample is diluted with cryoprotectant to protect the sperm from freezing conditions and distributed into cryovials. Each semen sample will yield one or more vials, the volume per vial (up to 1.8 ml) and the number of vials being determined by the volume and quality of the sample. Each vial is labeled with the patient’s name, the freeze date, and the vial number. The vials are slowly cooled, then frozen and stored at a recorded, unique location in our liquid nitrogen tanks. Generally, following freezing of the first sample, a small volume of semen is thawed to determine the success of the freezing process and the number of motile sperm per vial. Initial and post-thaw sperm counts and motilities are usually not done on samples received subsequent to the first sample.THE NUMBER OF SEMEN SAMPLES TO FREEZEBased upon knowledge of semen quality, conception rates, current technology, anticipated sample need, and time constraints, the patient, with the advice of his physician, must decide how many samples to freeze. Please be mindful that sperm cryopreservation does not guarantee future reproductive success no matter how many samples are frozen. The goal is to preserve a reasonable chance at producing a pregnancy.The
Andrology/Embryology Laboratory
recommends that sufficient sperm samples be cryobanked to provide
thawed
sperm for at least 4 intrauterine inseminations containing at least
10-20
million motile sperm each. The number of samples needed to
achieve
this is entirely dependent on the sperm count and motility of each
ejaculate.
For example, individuals with normal sperm parameters may satisfy this
level by freezing 2 semen samples. Individuals with less than
optimal
sperm parameters may prudently freeze several samples. Samples less
than
optimal for IUI may effectively be used in IVF. It is understood that
some
patients may not have sufficient time to freeze multiple samples before
undergoing their medical treatments. The Laboratory will provide the
cryopreservation
data to the patient’s physician and will indicate whether additional
freezing
is recommended. Such a recommendation should not be considered a
requirement.
The Laboratory does not have a comprehensive history of the patient’s
needs
or future desires, so the recommendation is simply based on the semen
parameters
and the number of samples previously frozen. Regardless of the
number
of samples cryopreserved, the options for their use should be carefully
considered when the patient is ready to consider attempting a pregnancy.
LENGTH OF TIME SEMEN SAMPLES MAY BE FROZENTheoretically, the viability of cryopreserved semen may be maintained indefinitely because it is stored in a liquid nitrogen freezer at a temperature of -196o C. While it is generally suggested that 10 years be considered a storage goal, pregnancies have been reported from samples stored as long as 13 years.SCHEDULING APPOINTMENTSAppointments to cryopreserve semen are scheduled Monday through Friday from 7:30 a.m. to 1:00 p.m. Two to three days of sexual abstinence is recommended before each appointment. Optimally, samples are collected in one of the private rooms next to the lab, or alternatively, may be collected elsewhere and brought in. Samples should be collected in a sterile Andrology Lab collection container or in a special condom provided by the Andrology Lab for a nominal charge. Samples collected elsewhere should be brought to the Andrology Lab within one hour of collection and kept at body temperature during transport to the Andrology Lab. The first appointment will take about one hour; successive appointments, less time.REQUISITIONA requisition (order) for sperm cryopreservation provided by the patient’s physician is required before the initial appointment can be made. Requisitions may be FAXED to the Andrology Lab at 503-418-3708, or mailed. The Andrology Lab will FAX/mail the cryopreservation results to the requesting physician, who is responsible to provide interpretation of the semen parameters to the patient as well as advice on the number of samples to freeze.CONSENT FOR THE USE OF CRYOPRESERVED SEMENCryopreserved sperm is the property of the individual who produced the specimen(s) regardless of his marital status. Any use of these samples for reproductive purposes is at the sole discretion of this individual. This individual must provide written consent for their use, for example, for intrauterine insemination of, or IVF with, his female partner or designated recipient. This also applies to the posthumous use of the samples. Control over the disposition of frozen sperm samples does not automatically transfer to a spouse, partner, or to relatives in the unfortunate circumstance that the patient who provided the samples is deceased. Future use of the samples is contingent upon written documentation from the patient attesting to his wishes under these circumstances. Please contact the Andrology Lab supervisor for further information regarding consents for the use of cryopreserved sperm.FEES FOR CRYOPRESERVATION OF SEMEN
Subsequent years of Sample Storage will be requested from you in writing on the Storage Renewal Form and payable in advance. Annual rates apply for each year or any portion of a year and are non-refundable. Directed sperm donation falls under the FDA regulation of tissue products. To meet these regulations and our own internal policies and procedures, it is necessary to cryopreserve the semen, to test and screen the donor on the day of, or within 7 days before or after, the first donation, and to repeat the tests to provide a minimum 6 month quarantine. After the 6 month quarantine, University Fertility Consultants (UFC) reviews testing and screening results and determines whether the donor is eligible or ineligible. Under some circumstances, samples from ineligible donors may be released for use after obtaining the physician signature on an ineligibility notification form. Physicians at UFC are pleased to offer directed sperm donation as an option to their patients and will provide a written order to the OHSU Andrology Lab to begin the process. I. Relevant Communicable Disease Testing and Screening a. Testing is to be performed within 7 days before or after freezing the first semen sample but preferably on the same day. Testing is also to be performed to provide a minimum six month quarantine. The tests, run as a panel, include:
b. Screening 1.Physical Examination
Donors must obtain an
OHSU Andrology Lab Donor Physical Examination
form to give to the physician for him/her to complete. Any physician
may conduct the exam. In the Portland area, Dr. Eugene Fuchs,
503-525-0071, a specialist in male fertility and advisor to the
Andrology Lab donor program, performs such examinations for a moderate
fee. The examination must take place on the day of, or within 7 days
before or after, freezing the first semen sample. 2.Medical History Interview
The OHSU Andrology Lab
will conduct a 10-15 minute interview, either in
person or on the phone. The interview must take place on the day of, or
within 7 days before or after, freezing the first semen sample. If the
first semen sample is frozen at OHSU, the interview will take place at
the time of that freeze. If not, the donor should call the Andrology
Lab to schedule.II. Cryopreservation of semen Samples may be frozen at the OHSU Andrology Lab or at another FDA compliant laboratory if such laboratory agrees. For a discussion of the number of samples to freeze please discuss the contents of this with the managing physician. III. Fees
Fees are subject to change without notice. A physical exam performed by a doctor is needed to complete eligibility. This cost is not included here since you may use your doctor or ours. For questions and to get started with the process: Please call the OHSU Andrology Lab, 503-418-3708. Hosted at Infertility
