What is Sperm Storage?
Sperm storage or sperm cryopreservation or sperm banking are all terms used to define the rapidly growing use of male fertility preservation. Sperm is collected, typically through masturbation, and frozen in cryovials or straws then stored in liquid nitrogen-filled tanks. This has proven to be an extremely effective means of preserving sperm, and when combined with the appropriate storage and shipping protocols, no one knows for how long the sperm can be preserved. However, twins were recently born from 40 year old cryopreserved sperm, shattering the previous record of 28 years.
Who Uses Sperm Freezing?
- Cancer Patients
- Pre-Vasectomy Patients
- Military Personnel, Police Officers, Firefighters
- High Impact Athletes
- Transgender Clients
- Advancing Paternal Age
By far the largest group of sperm storage users are male cancer patients. Due to the high cure rates for many types of cancer, oncology professionals are more frequently directing patients to male fertility preservation options prior to cancer treatments that could leave them infertile.
The Long-Term Sperm Storage Experts
Since 1990, ReproTech, Ltd. has been the leader in long-term storage of cryopreserved human reproductive tissues. It is all we do.
With four facilities strategically located throughout the U.S., and an ever expanding network of Fertility Preservation clinics, we’ve created the most convenient, effective, and affordable means for collecting, storing, and returning cryopreserved sperm.
Each of our four locations are monitored 24/7 by state-of-the-art monitoring systems, which record temperature changes as small as 0.01 degrees Celsius. Additionally, all tanks are manually monitored on a weekly basis by our experienced personnel, and our facilities are under 24-hour security and surveillance. Each facility has on-site back-up, bulk nitrogen storage, and all electronic data is backed up daily with off-site data storage.
Sperm storage and sperm cryopreservation is fast, efficient, and reliable when you choose ReproTech. Your options include the convenience of our OverNite Male™ Kit—for at home, expedited specimens—or you can work through the largest network of sperm freezing centers in the world to find a clinic near you. Either way, you’ll have peace of mind knowing your future is safe with the worldwide leader in long-term sperm storage.
Sperm Freezing Centers for Cancer Patients
ReproTech works closely with fertility service centers across the United States to make sperm cryopreservation services available nationwide. While RTL does not provide sperm freezing services, our network of freezing centers do. Once specimens have been preserved, we coordinate the transportation of your frozen semen to RTL for long-term storage.
Sperm Banking from Home (Sperm Banking by Air)
The OverNite Male™ Kit is a convenient tool for patients who are unable to travel to one of the many ReproTech Fertility Preservation Network Clinics. These patients can now collect their specimens at home and FedEx® the specimen(s) directly to the University of Illinois at Chicago Andrology Laboratory using our OverNite Male™ Kit. The OverNite Male™ Kit is the original overnight sperm banking system and the only one with 15 years of proven success. Click here for more information.
Sperm Collection Options
Testicular Sperm Extraction (TESE) and Sperm Freezing
When it is not possible to produce a sperm sample for storage, sperm can often be obtained from a testicular tissue biopsy using a technique called testicular sperm extraction (TESE). In many cases, sperm can be retrieved from the testes of men who have become infertile due to cancer treatments. TESE is a common procedure in many fertility service clinics across the country for adult men, but is less commonly used (and considered experimental) for fertility preservation in adolescent boys. TESE is an outpatient procedure where testicular tissue is surgically removed and frozen for future use. When needed, the testicular tissue is thawed, evaluated, and an attempt is made to locate and retrieve sperm cells, which may be used in combination with Intra Cytoplasmic Sperm Injection (ICSI).
Testicular Tissue Freezing for Pre-Pubescent Boys
Sperm banking is not an option for prepubertal boys who are not yet producing sperm. However, these boys do have stem cells in their testes that are poised to begin producing sperm at puberty. Currently there are some experimental studies underway to preserve testicular tissue obtained by biopsy and freeze it for future use. The tissue contains stem cells which will be able to start spermatogenesis (sperm production). Testicular tissue freezing is considered experimental and is generally only offered in a research setting with IRB oversight. Several studies are developing protocols that will enable scientists and physicians to use the frozen/thawed testicular tissue and stem cells to produce sperm in the laboratory or by re-implanting, years later, back into the individual. Research has proven these strategies are effective in animals and it is envisioned that they will also be effective in humans.
