Up to (99%) of women worldwide may use birth control for at least 30 years. However, most modern female contraceptives containing hormones can have undesirable side effects. Among the limited hormone-free options, the fertility awareness method is the safest and most effective when used correctly. This study explores a time-tested, safe, and effective barrier contraceptive called FemCap. FemCap not only aids in pinpointing the day of ovulation but also integrates electronic period-tracking technology to enhance the efficacy of the fertility awareness method. Stress Urinary Incontinence is a prevalent issue affecting women of all ages, often suffering in silence. Our research aims to address the unmet needs in women’s reproductive health. We have discovered that FemCap can function as a pessary to manage Stress Urinary Incontinence by providing support to the bladder neck and straightening the urethra, thereby restoring the competence of the urethral sphincters. FemCap has emerged as a powerhouse for fertility awareness and stress urinary incontinence. However, due to the limitations of this study, the authors welcome any investigators who can validate our findings as well as provide suggestions to enhance the overall value of this research for the benefit of all women.
