About

In Vitro Fertilization (IVF) success is below 40%, with Embryo Transfer the leading cause of IVF failure. This clinical investigation aims to evaluate if the levels of an intrauterine biomarker dissolved in the uterine fluid (alone or as a complex biological marker) can predict the outcome of embryo transfer.

Full description

Seedchorny02 is an exploratory study, with blind evaluation by third parties, in a single center and without influencing clinical practice. The goal of this investigation is to evaluate if the levels of an intrauterine biomarker that is dissolved in the endometrial fluid can predict the outcome of embryo transfer, when measured the day before or on the day of embryo transfer.

80 IVF volunteers in a frozen embryo transfer cycle with high-quality day-five blastocysts are expected to be recruited. For intrauterine measurement, the investigational device Seedchrony RUO 02 will be used. Seedchorny RUO 02 has a microsensor integrated into the transfer catheter to measure the biomarker level in the uterine fluid entering the transfer catheter. Other patients' clinical variables and IVF cycle parameters (hormonal levels, ultrasound parameters, embryo quality grades, and transfer protocol) will also be collected.

Primary variable: Relationship between intrauterine dissolved biomarker concentration (alone or as a complex biological marker) and the outcome of the embryo transfer.

Notes: The intrauterine biomarker concentration is measured twice: the day before the transfer and on the transfer day. Complex biological marker refers to combining the concentration of the biomarker on both days and/or with other clinical variables of the patient/embryo.

The outcome of the embryo transfer is evaluated as:

Chemical pregnancy: positive pregnancy test (blood hGC detection); Clinical pregnancy confirmed by ultrasound at week six (detected gestational sac); Ongoing pregnancy at week eight, confirmed by ultrasound at week eight (detected gestational sac and heartbeat).

Enrollment: 80 estimated patients

Sex: Female

Ages: 18 to 37 years old
