Receptivity of the Uterus

The issue of uterine receptivity and its effect on pregnancy is one of the most frequently asked questions by our patients.

 

Studies that would implicate the uterine receptivity as a major factor in infertility treatment success are lacking. On the other hand, there is evidence suggesting that the role of uterine lining receptivity as a decisive factor in human conception is limited.

 

Since women can have ectopic pregnancies (tubal, ovarian, cervical, abdominal), embryos seem to be able to implant in environments that would be considered hostile.

 

For many years it has been evident that the probability of success of Egg Donation treatments depends primarily on the donors' egg quality and that the age of the recipient or her uterine receptivity is not an important factor.

 

Contemporary data suggests that uterine receptivity does not have a significant effect on the success of infertility treatments, and that pregnancy outcome is determined at the moment of the creation of an embryo (the moment of fertilization). Subsequent pregnancy events (embryo hatching, implantation, and further fetal development) are merely playing out of this predetermined outcome.

 

In conclusion, embryo quality (egg quality) is the pivotal factor in a successful reproductive outcome.
