Transciptomic Modification Induced by miRNAs in Endometrial Fluid

Human Embryonic Transciptomic Modification Induced by miRNAs Secreted by Human Endometrium to Endometrial Fluid

The purpose of this study is to understand the mechanism of communication between the uterine environment and the preimplantation human embryo. The investigators are interested in understanding how the in-utero environment during the window of implantation is different in normal weight and overweight/obese women and how this may impact the programming of the developing embryo.

Inclusion Criteria:

• Meet the WHO criteria for normal weight (BMI < 25) and overweight/obese (BMI > 25)
• Age 21-45

Exclusion Criteria:

• Age < 21 or > 45
• Women with history of hysterectomy
