Cervical caps and cups have been used commonly for the enhancement and support of fertility. The primary purpose for these devices is to physically place the ejaculate as close as possible to the cervical os in order to maximise the amount of spermatozoa that swim through the cervical mucus on their way to fertilization(1) . Cervical caps have been shown to significantly increase the number of spermatozoa entering [the cervical mucus] by more than 300% (2) .


An increased concentration of spermatozoa in the cervical mucus has a beneficial effect on the chances of conception (3). A couple with a high sperm-cervical mucus penetration has a significantly higher chance of conceiving after 6 months than couples with a low penetration rate (29.1% vs. 2.3%).

“Even in couples with normal sperm quality of the male, markedly more pregnancies were achieved when penetration of the cervical mucus was good”(4) .

The FERTI·LILY Conception Cup combines the known benefits of cervical caps with ease of use and comfort to help couples feel more in control of their fertility. The FERTI·LILY cup does not interfere with any of the natural processes of conceiving(5,6). It’s comfortable, easy to use, and because it’s inserted after sex, it does not disturb the intimacy of the moment.

While the FERTI·LILY Conception Cup has no bearing on ovulation and other factors that can influence fertility, it has been proven to increase the chances of conception for otherwise healthy couples. The FERTI·LILY has been developed in collaboration with European gynaecologists and fertility specialists.
