Detailed Description
Objective: To investigate the effects of tamoxifen on endometrial thickness and pregnancy outcome in women with thin endometrium undergoing frozen thawed cycle.
Study design: This is a single center, randomize control clinical trial. We plan to recruit 100 patients from Mar 2017 to Dec 2019, who failed to develop an adequate endometrial thickness in previous frozen embryo transfer cycle twice or even more times and willing to have another attempt, dividing into two group, one prepare the endometrium through ovulation induction with tamoxifen and progesterone(Study Group), the other is hormone replacement cycle (control group).
Intervention: Study Group will give endometrial preparation with tamoxifen and progesterone, control group will prepared with estrogen and progesterone supplementation.
Main outcome measures: The primary outcome of the study was endometrium thickness and clinical pregnancy rate, the secondary outcomes are cycle duration, cycle cancellation rate, implantation rate, miscarriage rate, live birth rate.

Intervention / Treatment |
---|---|
Experimental: study group
Patients in study group will receive tamoxifen at a daily dose of 40 mg from day 3 to day 8. Follicle diameters are monitored by transvaginal ultrasound and serum levels of E2, P are tested on day 9.
If there is a dominant follicle (almost 12 × 12 mm in diameter), endometrial thickness and endometrial pattern, as well as follicular diameters, were monitored daily or every other day till embryo transfer.
Serum levels of E2, P are tested on the day before ovulation.
If there isn't dominant follicle and intramuscular human menopausal gonadotropin at a dose of 75-150 IU was administered each day after day 12 if there follicle development was poor.
The embryo transfer day is decided according embryo development.

Patients in study group will receive tamoxifen at a daily dose of 40 mg from day 3 to day 8.

Active Comparator: control group
Patients in control group will receive estradiol valerate at a dose of 3 mg twice per day from day 3. Follicle diameters are monitored by transvaginal ultrasound and serum levels of E2, P are tested on day 9.
If endometrial thickness <7mm and E2<100pg/ml, the dose of estradiol valerate can increase or combine other estradiol.
Endometrial thickness and endometrial pattern, as well as follicular diameters, were monitored daily or every other day till embryo transfer.
Serum levels of E2, P are tested on the day before endometrium transformation.
The embryo transfer day is decided according embryo development.
Serum levels of E2, P are tested on the day before embryo transfer.

Patients in control group will receive estradiol valerate at a dose of 3 mg twice per day from day 3.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
endometrium thickness
Time Frame: 1-3 month
|
Endometrial thickness was defined as the maximal distance between the echogenic interfaces of the endometrium and the myometrium in the plane of the central longitudinal axis of the uterus.
|
1-3 month
|
clinical pregnancy rate
Time Frame: 1-2years
|
Clinical pregnancy was considered with the presence of a gestational sac containing yolk sac at transvaginal ultrasonography, including ectopic pregnancy.clinical
pregnancy rate is the number of clinical pregnancy patients /the total number of transferred patients in the group.
|
1-2years
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
cycle duration
Time Frame: 1-3 month
|
the total time of endometrium preparation
|
1-3 month
|
cycle cancellation rate
Time Frame: 1-3 month
|
cycle cancellation rate is the number of patients that cancell embryo transfer /the total number of patients in the group.
|
1-3 month
|
implantation rate
Time Frame: 1-2 year
|
Implantation rate was determined by the number of gestational sacs and the total number of embryos transferred at least 4 weeks after embryo transfer.
|
1-2 year
|
miscarriage rate
Time Frame: 1-2 year
|
miscarriage rate is the number of patients that find pregnancy loss /the total number of transferred patients in the group.
|
1-2 year
|
live birth rate
Time Frame: 1-2 year
|
live birth rate is the number of patients that delived /the total number of transferred patients in the group.
|
1-2 year
