A Novel Approach to Endometrial Preparation in Recipients of Donor Cycles
This study compares two different methods to prepare the uterine lining of recipients for
implantation in cycles using donor eggs. The study method requires less time than the
standard method.
It is hypothesized that both methods would be suitable for use in egg donor cycles.

It is hypothesized that both methods would be suitable for use in egg donor cycles.
Currently a combination of medications is used to prepare the uterine lining of recipients
for implantation in egg donor cycles. The protocol used most commonly is as follows:
Initially the individual's own pituitary-ovarian system is suppressed using a GnRH agonist
so there are not conflicting signals sent to the uterus. This is followed by hormonal
medication identical to what is secreted by the ovaries to prepare the uterine lining for
subsequent embryo transfer in donor egg cycles.This preparation typically takes a minimum of
four weeks.
This study will compare a different medication, a GnRh antagonist (which is commonly used in
IVF) to suppress an individual's system during the preparation of the uterine lining. This
protocol would generally take only two weeks to prepare the uterine lining.
