The Need For Sperm Banking

Men who are facing chemotherapy and/or radiation therapy for testicular cancer, transurethral resection of the prostate, vasectomy surgery or who have high risk occupational exposure to toxic substances should consider long-term freezing of sperm as they are at risk for sterilization, reduction in fertility potential or genetic damage. Many men in contact sports and those in military service also choose sperm banking as a means of preserving fatherhood.

Sperm Banking From Home

Often times, due to time constraints or geography, men seeking to preserve sperm are not able to get to one our Freezing Centers throughout the country. Often men just feel more comfortable collecting their specimen in the comfort and privacy of their own home.

The OverNite Male™ Kit is the perfect answer to these concerns. OverNite Male gives men the comfort of being able to securely bank their sperm within 24 hours of their decision to do so. You can either order a kit online or by phone. Your Kit will be FedEx’d to your home with next day delivery M-Th if ordered by 1 PM Central Time. The Kit is easy to use and virtually foolproof. Once your specimen is within the storage media, it is now secure and safe for transport. You need only FedEx your kit back using the provided labels and you’ve preserved your hopes for fatherhood.

Your specimen will be processed at the University of Illinois at Chicago Andrology Labs, one of the leading labs of its kind in the world. Your specimens will then be stored at ReproTech Ltd., the leading long term storage cryobank in the world.

How Many Specimens Should be Collected?

Once the need for sperm banking is established by the patient and his physician, the patient contacts ReproTech, Ltd. to order an OverNite Male™ Kit or kits. While the patient will always decide on the number of specimens to cryopreserve, sperm quality and time will often limit the number of kits a patient may use. Ironically, men with lower quality sperm typically collect fewer specimens as they will be used in more advanced procedures. Men with higher quality sperm may want to collect more specimens since they will benefit from less technical and less expensive reproductive procedures to achieve pregnancy.

Keep in mind that with today's advanced reproductive technologies, even one cryopreserved specimen can provide enough sperm for multiple attempts at pregnancy.

Generally 2—3 days sexual abstinence is preferred between collections, thus producing multiple specimens can take up to 2 weeks. However, the collection interval and the number of collections can be adjusted to accommodate physicians who believe this time frame is too lengthy and/or for therapy or surgery which must begin sooner.

Sperm Freezing Success Rates"

In general, sperm cells freeze very well. Generally, 40%—60% of sperm retain motility when thawed, depending upon the quality of semen. However, many patients with testicular cancer have reduced sperm count and motility even before therapy. Poor quality specimens do not freeze as well as normal semen samples.

Required Testing

Standards and/or regulations require that patients complete the following serology/virology testing prior to release of specimens from ReproTech for transfer back to patient's clinic for infertility treatment: HBsAg and Anti-HCV, in addition to Anti-HIV 1&2. These specimens will be assessed standard storage fees.

We will accept specimens from patients without Anti-HIV 1&2 (AIDS) testing or who have tested reactive for one or more of the following: Anti-HIV 1&2, HCV, and HBsAg, however, potentially infectious storage fees will apply.

Note: the above testing is required for Client Depositor sperm banking. The OverNite Male Kit may not be used for Donor sperm banking.

How to Attempt Pregnancy with Frozen Sperm

For specimens with normal count and motility, artificial insemination of thawed sperm into the spouse/partner's cervix is performed by a fertility specialist. This will require timed ovulation monitoring during the desired month of conception with 1—2 inseminations (1—2 vials each) around the time the egg is released.

For specimens with below normal parameters for sperm count and/or motility, special Assisted Reproductive Technologies (ART) such as In Vitro Fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) may be necessary.

Your cryopreservation results and your partner's own fertility will determine the type of fertility treatment appropriate for you. It is important to learn from your referring physician, ReproTech or from the University Andrology Laboratory the quality of your frozen specimens in order to determine in advance what type of treatment will be most appropriate for your attempt at pregnancy.

Arrangement for the shipment of vials should be done at least one month prior to the time you wish to begin artificial insemination or specialized ART procedures. If you need your samples shipped to another location in the United States, arrangements can be made to ship your specimens via FedEx . Please contact ReproTech for shipping information approximately 30 days prior to use.
