A RCT on the Effect of Endometrial Injury on Improving Ongoing Pregnancy Rate in Subfertile Women Undergoing FET Cycles
A Randomized Controlled Trial on the Effect of Endometrial Injury on Improving Ongoing Pregnancy Rate in Subfertile Women Undergoing Frozen-thawed Embryo Transfer Treatment Cycles

Detailed Description
Consecutive women attending subfertility clinic at Queen Mary Hospital, University of Hong Kong who are scheduled for FET treatment will be recruited. Women who have normal uterine cavity will be randomized into study and control groups in 1 to 1 ratio according to a computer-generated randomization list.
For patients in the study group, in the cycle immediately preceding the scheduled FET treatment, an endometrial biopsy would be arranged on day 21-23 of the menstrual cycles and they will be instructed to use non-hormonal means of contraception during that cycle. For patient in the control group, a similar procedure would be performed on the same timing during the preceding cycles without entering the uterine cavity, ie endometrial biopsy catheter entering the endocervical canal without entering the endometrial cavity. All patients will then proceed to FET treatment in the next cycle as scheduled.
The FET would be carried out as per our protocol. In short, patients attend the clinic daily from 18 days before the next expected period for the determination of serum E2 and luteinising hormone (LH) concentrations until the LH surge, which was defined as the day on which the LH level was above 20 IU/L and doubled the average of the LH levels over the past three days. For patients with irregular menstrual cycles or no ovulation demonstrated during natural cycle monitoring, clomiphene citrate (CC, Clomid, Merrell, Staines, U.K.) 50-100 mg will be given daily for five days from Days 3-7. The cycle will be monitored by blood tests from day 10 of the cycle as above. FET was performed on the third day after the LH surge. Up to two frozen-thawed embryo(s) can be transferred. No luteal phase support is used. On-going pregnancy rates, defined as viable fetuses beyond 10-12 gestational weeks, between the two groups will be compared.
We should measure endometrial thickness on LH+1 in natural and clomid-induced cycles.

---|---|
EXPERIMENTAL: EA
in the cycle immediately preceding the scheduled FET treatment, an endometrial biopsy would be arranged on day 21-23 of the menstrual cycles and they will be instructed to use non-hormonal means of contraception during that cycle.
|
The procedure was performed in a standard approach using a Pipelle catheter (Pipelle de Cornier, Laboratoire C.C.D., France).
The pipelle catheter was introduced through the cervix up to the uterine fundus.
The piston was drawn back to the end of the sheath to create a negative pressure.
The sheath was rotated and moved back and forth between the fundus and internal os for at least 3-4 times before it was gently withdrawn.
|
PLACEBO_COMPARATOR: Control
The procedure was performed in a standard approach using a Pipelle catheter (Pipelle de Cornier, Laboratoire C.C.D., France).
The pipelle catheter was introduced through the cervix but not into the uterine cavity, only entering the endocervical canal as control.
|
Using pipelle catheter without entering the uterine cavity.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |

Implantation rate
Time Frame: 4-6 weeks after embryo transfer
|
Implantation rate = number of gestation sacs on ultrasound (USG) / number of embryos transferred
|
4-6 weeks after embryo transfer

Clinical pregnancy rate
Time Frame: 6 weeks after embryo transfer
|
Clinical pregnancy rate is the presence of gestation sac on USG scan.
|
6 weeks after embryo transfer
