The Stork OTC is a home-use conception aid that combines an innovative applicator and an established conception technique — cervical cap insemination. The Stork OTC utilizes cervical cap insemination, giving couples the ability to use this technique in the privacy of home, without a prescription.

The Stork OTC can be a first-step treatment option for couples before more invasive procedures are considered; bridging the gap between natural intercourse and costly, in-office treatment options (i.e., IUI or IVF). The Stork OTC collects semen into the cervical cap with a condom-like sheath (the Conceptacle) worn during intercourse (or alternatively, donor sperm can be used with the device). The sperm is then delivered to the opening of the cervix by way of the applicator. The cap remains in place for up to 6 hours, after which it is removed with a simple tampon-like pull chord.

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. The Stork OTC contains a cervical cap inside a condom-like sheath. It is used to collect semen into a cervical cap then deliver it to the outside of the cervix as an aid to conception. The Stork OTC should be used during the ovulatory phase of the menstrual cycle. The Stork OTC Cervical Cap should not be left in place for longer than six hours.

Historically, cervical caps have been used for both conception and contraception 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.
