New Clinical Study Demonstrates the Stork® Delivers 3X a Higher Concentration of Sperm to the Cervix Compared to Natural Intercourse.

Objective: Efficacy study designed to compare the number of sperm in the cervical mucus following the use of the Stork home conception aid with the number of sperm in the cervical mucus following natural intercourse.

Results: Post-coital data was collected demonstrating on average, a 3.23 higher value of sperm concentration at the cervix 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 and natural intercourse.

“Three times the sperm value is quite significant for so many couples, especially with the growth of male factor infertility. Understanding the growing value of semen for successful conception, and having a technology like The Stork® that can deliver more sperm to the cervix than natural intercourse, this at-home kit for conception may greatly impact many couples on their path to building a family. The Stork makes sense.”

Study Design: 15 couples enrolled in the study. Non-blinded and non-randomized, single-center comparison study comparing The Stork® to natural intercourse, using the subjects as their own control/baseline. Subjects used both the Stork kit for conception and the natural intercourse method to evaluate concentrations of sperm in the cervical mucus.
