OverNite Male™ Facts & FAQs

The Need For Sperm Banking

Patients 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 people in contact sports and those in military service also choose sperm banking as a means of preserving fertility.

Sperm Banking From Home

The OverNite Male™ Kit is ideal for people who are either unable to reach one of our freezing centers or who prefer to collect their specimen in the comfort and privacy of their own home.

You can either order a kit online or by phone. Your kit will be shipped via FedEx to your home with next-day delivery M-Th if ordered by 1 PM Central Time. The kit is easy to use and comes with concise and clear instructions. Once your specimen is within the transport media, it is now secure and safe for shipping. You need only return your kit to FedEx using the prepaid label and you’ve preserved your hopes for fertility.

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, the leading long-term storage cryobank in the world.

About the OverNite Male™ Kit

The OverNite Male Kit is the original overnight sperm collection kit. Our gold standard kit has been developed by Gail S. Prins and her team at the University of Illinois at Chicago Andrology Lab in 1994. The OverNite Male Kit is by far the most simple and secure semen collection kit on the market. Although many have tried to copy the kit, it’s important to know knock-off at-home collection kits seldom match the quality and security of the original.

Due to the unique partnership of UIC Andrology Lab and ReproTech, and their commitment and experience in fertility preservation, the OverNite Male Kit is by far the most cost-effective and convenient kit to use. When you compare the true costs combined with the level of service, quality of help, and the security of ReproTech’s storage, there truly is no comparison and no better option to trust your hopes.

Cost Compare to Other Kits

Although our OverNite Male™ Kit stands out as the most economical semen collection and storage option, it is also the most reliable at-home collection kit. OverNite Male is brought to you by the world leader in long-term semen storage. So you can be confident that your hopes are in the right place.

We also offer a prepaid 3-year storage period, which is only $875.00 and also includes the the same great services at our low prices.

*An additional annual storage fee of $150 is assessed for patients who do not forward infectious disease testing and/or who have tested reactive for an infectious disease.

How Many Specimens Should be Collected?

Once the need for sperm banking is established by the patient and physician, the patient contacts ReproTech, 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. Patients with lower quality sperm typically collect fewer specimens as they will be used in more advanced procedures. Patients 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 to 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.

What if I Already Started Hormone Therapy?

Trans patients who are planning to start gender affirming hormone therapy should freeze their sperm before beginning therapy. However, please consult with your doctor before ordering an OverNite Male™ Kit if you will need to delay or pause your therapy to allow for a sperm collection.

If you have already started exogenous hormones used in gender affirming hormone therapy, it is possible that you will not have viable sperm in your collection. Please consult with your doctor before ordering the OverNite Male™ Kit.

If you order an OverNite Male™ Kit and do not return the kit, or if your collection does not have viable sperm, you will only receive a partial refund of the total kit cost. Please call 651-489-0827 or 888-586-3389 for more information.

What are the considerations for Multiple Collections?

You can order multiple OverNite Male™ Kits for multiple collections to increase the number of specimens available for future use. Generally 2 to 3 days of sexual abstinence is preferred between collections, thus producing multiple specimens can take up to 2 weeks.

For patients who do not have much time before beginning fertility threatening therapies, in some instances the collection interval and the number of collections may be adjusted to accommodate an expedited collection process. Please consult your physician who can evaluate the best course for your treatment plan.

Can I Use the OverNite Male Kit for Donor Sperm Banking or With a Surrogate?

The OverNite Male™ Kit is only for Client Depositor sperm banking. This means you can only use your sperm, collected with this kit, with your sexually intimate partner or future partner.

The OverNite Male™ Kit may not be used for donor sperm banking or for use with a gestational carrier/surrogate.

If you intend to use a friend or other third-party for sperm donation, or if you know you will need to use a gestational carrier/surrogate, you should work with a fertility clinic that can assist you with the FDA required testing and screening for donor eligibility determination.

Sperm Freezing Success Rates

In general, sperm cells freeze very well. Generally, 40% to 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 for Semen Specimens

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 or for use with a gestational carrier/surrogate.

Pregnancy with Cryopreserved Sperm

For specimens with normal count and motility, insemination of thawed sperm into the spouse/partner’s uterus is performed by a fertility specialist. This will require timed ovulation monitoring during the desired month of conception with 1 to 2 inseminations (1 to 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 verify (either from your referring physician, ReproTech or from your 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.
