How Evie Increases Pregnancy Rates
In natural conception, sperm is released gradually into the uterus and migrate to the fallopian tubes over several hours. The SRI technique mimics the process and increases the duration of potential contact between the sperm and egg. This slow and gradual process decreases the risk of immunological reactions and polyspermia (a process whereby too many sperm fertilise an egg, rendering it non-functional). The risks of sperm from discharging into the abdomen and flowing back into the vagina.
In comparison with standard intrauterine insemination (IUI), Evie is a non-invasive device that uses the SRI technique to deliver sperm gradually into the uterus over a period of four hours. This improves pregnancy success rates as it decreases the risk of sperm from discharging into the abdomen, through the fallopian tubes, and flowing back into the vagina.
What can I expect during the procedure?
The process for attaching Evie to a patient is similar to other routine examinations, such as a pap smear.
- A fine catheter is inserted into the uterus and a small single-use mechanical pump is worn on the thigh. This is generally a simple and quick process. You may experience mild cramping and your fertility specialist may recommend taking mild pain relief to manage the discomfort.
- The fertility specialist will talk you through the simple process of removing the device after four hours. Most patients are happy to leave the clinic once Evie is fitted on them. For the duration of the treatment, you may perform light activities, or rest if you prefer. As a reminder, you will be given a copy of the start and end times and instructions for removal before you leave the clinic.
