Protocol summary

Study aim
The aim of our study is to assess the advantage of HCG injection in secretory phase plus estrogen and progesterone to transfer cryopreserved-thawed embryos
Design
Primary outcome chemical pregnancy that is evaluated 2 weeks after embryo transfer.
Settings and conduct
This randomized clinical trial was conducted at the Yazd Research and Clinical Center for Infertility.This study was a randomized clinical trial. Infertile women who were candidates for frozen-thawed embryo transfers entered the study and were divided into two groups, HCG and control. The endometrial preparation method was similar in both groups.
Participants/Inclusion and exclusion criteria
All women have failed previous in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI), and they have cryopreserved embryos transfer.Women older than 38 years, those with a body mass index (BMI) >30 kg/m2, history of endocrine disorders, and severe endometriosis were excluded from the study.
Intervention groups
In case group, HCG is injected 5000 IU in the first day of progesterone injection and in the embryo transfer time.
Main outcome variables
Primary outcome includes chemical pregnancy that is evaluated 2 weeks after embryo transfer

Intervention groups

1

Description
Intervention: all women receive estradiol valerate 6 mg PO per day from the second day of menstrual cycle. Endometrial thickness is assessing by using vaginal ultrasonography since 13th day of cycle.

Abstract of published paper
Abstract Background: Human chorionic gonadotropin (HCG), one of the initial embryonic signals, is probably a major regulator of the embryo-endometrial relationship. This study aims to assess the advantage of HCG supplementation during the secretory phase of hormonally prepared cycles for the transfer of cryopreserved-thawed embryos. Materials and Methods: This study was a randomized clinical trial. Infertile women who were candidates for frozen-thawed embryo transfers entered the study and were divided into two groups, HCG and control. The endometrial preparation method was similar in both groups: all women received estradiol valerate (6 mg) po per day from the second day of the menstrual cycle and progesterone in oil (100 mg) intramuscular (I.M.) when the endometrial thickness reached 8 mm. Estradiol and progesterone were continued until the tenth week of gestation. In the HCG group, patients received an HCG 5000 IU injection on the first day of progesterone administration and the day of embryo transfer. Results: In this study, 130 couples participated: 65 in the HCG group and 65 in the control group. There was no statistically significant difference between groups regarding basic characteristics. Implantation rate, chemical pregnancy, clinical pregnancy, ongoing pregnancy, and abortion rates were similar in both groups. Conclusion: Although HCG has some advantages in assisted reproductive technology (ART) cycles, our study did not show any benefit of HCG supplementation during the secretory phase of frozen cycles (Registration Number: IRCT201107266420N4).
