The Stork OTC is a uniquely designed medical device you use at home, during ovulation, to assist your chances of becoming pregnant by using the cervical cap insemination technique. This smart technique enables the sperm to quickly bypass the vaginal tract and places the sperm as close as possible to the opening of the cervix, right where it needs to swim up through to get to the egg. The product can be used in private, at home, without a prescription.
The product includes an innovative applicator and a cervical cap within a condom-like sheath (Conceptacle). The Conceptacle is worn during intercourse to collect the semen into the cervical cap (the device can alternatively be used with donor sperm). The cervical cap is removed from the condom-like sheath, and inserted into the applicator. The applicator is inserted into the vaginal tract and the cervical cap of semen containing sperm is placed at the opening of the cervix. The cap remains in place for up to 6 hours, after which it is removed with a simple tampon-like pull string.
Historically, cervical caps have been used for conception dating back to the 1950’s. The cervical cap keeps the sperm at the opening of the cervix for up to 6 hours. Benefits of cervical cap insemination include:
• Pregnancy success rates of up to 20%, comparable to intrauterine insemination success rates (16-21%). • Prevention of backflow of semen into the vagina1.
• Prolonged exposure of the spermatozoa (Sperm cell) to the cervical mucus1.
• Enables sperm to bypass the vaginal environment quickly, reducing the risk of sperm loss in the vaginal
• Considered a less invasive method of aiding in conception with a limited number of risks2.
The Stork OTC uses this technique adding a special applicator to improve the delivery method of the cervical cap to the cervical opening.

• Couples trying to become pregnant without intercourse.

A post coital study (peer-reviewed and published in Surgical Technology International XXVII) demonstrates on average a 3.23 higher value of sperm concentration at the cervix with the Stork OTC compared to the value of sperm concentration with natural intercourse, for 85% of study participants. The remaining 15% of subjects saw no change in sperm concentration between the Stork OTC and natural intercourse.
Suggested use of the Stork OTC is on the three most fertile days of the female partner’s cycle. The Stork OTC conception device allows you in the privacy of your home to use the device when it is convenient and most comfortable for you. Please keep in mind, if you are using (1) Stork OTC device, it is best to use right before ovulation. If you are using (3) Stork OTC devices, please use one device on each of your three most fertile days of your monthly cycle. Rinovum recommends tracking your ovulation with an ovulation tracking to determine your most fertile days to use the Stork OTC.
Yes, you can have normal intercourse during the same month you are planning on using The Stork OTC. Research studies suggest male sperm count can decrease if there is ejaculation on a daily basis; it is often recommended that couples have intercourse every other day to build up their sperm production between ejaculations.
You can return to normal activities immediately after placing the cervical cap and removing the applicator. You should not have sexual intercourse while the cervical cap is inserted, as it may cause discomfort to you or your partner.
The cervical cap should remain in place for no more than 6 hours. Do not wear longer than 6 hours. Failure to remove the cervical cap could result in complications, including: obstruction of physiological discharge and menstrual flow from the uterus, pain, abrasion/ulceration, or infection.
Within our Instructions for Use, it states “If the withdrawal string breaks, retrieve the cervical cap manually. If you are unable to remove the cervical cap or any component of the device, contact your healthcare provider.”

The worst scenario that could occur from the cervical cap remaining within the vaginal tract for longer than the recommended 6 hours is you may experience some irritation, but the cap can easily be removed similar to a diaphragm, birth control ring, menstrual cup or even a tampon if the string gets lost. The cervical cap is within your vaginal tract and will not travel any further than your cervix. First, please make sure you wash your hands, recline back and insert your fingers to remove the cap. It is best if you remain calm and relaxed so your vaginal muscles do not contract, making removal more difficult. If you personally cannot reach the cervical cap, your partner may find it easier to remove. Please have your partner wash their hands and remove the cap for you.

If you find you are unable to manually remove the cervical cap, as suggested in our Instructions for Use, please reach out to your Healthcare Provider for guidance on removing the cervical cap.

Yes, you can urinate while the cervical cap is in place with no adverse effects.
The Stork OTC is indicated for over-the-counter home use by couples who have been unable to conceive naturally and who have received diagnoses of low sperm count, sperm immobility or unfavorable vaginal environment.

There are no publications that discuss whether cap usage can cause TSS (toxic shock syndrome). The Instructions for Use instruct the user to remove the cap four to six hours after insertion to reduce the risk of TSS. The risk of Toxic Shock Syndrome (TSS) exists for products like tampons and other vaginal devices. TSS is a rare but serious disease that may cause death. Warning signs of TSS include sudden fever (usually 102° F or more) and vomiting, diarrhea, fainting or near fainting when standing up, dizziness, or a rash that looks like a sunburn. If these or other signs of TSS appear, remove the cervical cap at once, and seek medical attention immediately. The Stork OTC is intended to assist you in achieving pregnancy. Pregnancy may involve serious health risks for both you and your unborn child. Consult your Healthcare Professional for possible risks before using The Stork OTC.
The device is not to be used by those for whom it is medically unsafe to engage in sexual intercourse or to become pregnant.
The product is non-sterile. To avoid contamination, customers are advised not to open or handle the device until they are ready to use it.
Implantation occurs after an egg has been fertilized. This takes place, on average, 6 to 12 days after ovulation and fertilization of the egg has occurred however every woman is different. The fertilized egg must travel through the fallopian tubes and into the uterus for implantation. Home pregnancy tests vary in how early they can detect the level of hCG hormone. Most healthcare providers recommend that you wait until you have missed your first period before taking a home pregnancy test; usually about two weeks after conception.
If you have any questions regarding fertility issues, please contact your Healthcare Provider. Rinovum is unable to provide medical advice on use of The Stork OTC.
