Study Arms:
- Drug: human chorionic gonadotropin (hCG) (Type: EXPERIMENTAL): Drug: human chorionic gonadotropin (hCG). A single intrauterine infusion of 500IU hCG dissolved in IVF media (Global-trademark) will be administered to participants in the experimental group three days after oocyte retrieval. Two days after this infusion, participant will return to clinic where a uterine lavage and an endometrial biopsy will be performed to obtain a sample of uterine secretory proteins and endometrial tissue, respectively, for research analysis.
- IVF media (Global-trademark) (Type: PLACEBO_COMPARATOR): Placebo Comparator for hCG. A single intrauterine infusion of IVF media without hCG will be administered to participants in the control group three days after oocyte retrieval. Two days after this infusion, participant will return to clinic and a sample of uterine secretory proteins and endometrial tissue, will be obtained via uterine lavage and endometrial biopsy, respectively, for research analysis.

Based on this trial design, predict the completion outcome and termination type (if applicable).
