- Registration Number
- NCT03518528
- Lead Sponsor
- University Hospital, Angers
- Brief Summary
The purpose of this study is to compare pregnancy outcomes of frozen-thawed embryo transfer after endometrial preparation with vaginal estradiol or transdermal estradiol and to evaluate women's satisfaction
- Detailed Description
Frozen-thawed transfer embryo are more and more frequent but to date, there is no consensus on the ideal management of the adequate endometrial preparation.
Artificial preparation of endometrium is commonly used in assisted reproduction center because it is more easy to schedule.
Estradiol could be administrate by oral, vaginal or transdermal, but no protocol seems to improve clinical pregnancy rates.
To investigator's knowledge, transdermal estradiol has never been compare to vaginal administration before frozen-thawed embryo transfer.
Because transdermal administration could improve satisfaction of patients and reduce duration of treatment (when compare to oral administration), the investigators conduct a prospective study to compare clinical pregnancy rate after transdermal or vaginal estradiol administration to prepare the endometrium before frozen-thawed embryo transfer.
The investigator also evaluate side effects and patients satisfaction in both protocol.
The patients choose if they prefer vaginal or transdermal protocol after receiving sufficient information during medical consultation.

- Arm && Interventions
Group Intervention Description transdermal Estradiol 100 µg transdermal estradiol (Vivelledot, Novartis) 100 µg on day 3, then 200 µg day 7 and every 4 days, until first pregnancy test. If pregnancy test is positive, treatment is to continue until 8 weeks. vaginal Estradiol 2 MG Vaginal estradiol (Provames, Sanofi) 4mg per day from day 3 to first pregnancy test. If pregnancy test is positive, treatment is to continue until 8 weeks
- Primary Outcome Measures
Name Time Method clinical pregnancy 12 weeks defined as fetal cardiac activity at 12 weeks of gestation
- Secondary Outcome Measures
Name Time Method treatment duration 21 days duration of treatment before transfer
chemical pregnancy 6 weeks Defined as serum HCG levels \>10 IU/L, 14 days after the embryo transfer, followed by a rapid decrease until being undetectable
plasmatic lh concentration on the day of transfer 21 days plasmatic lh concentration on the day of transfer
plasmatic progesterone concentration on the day of transfer 21 days plasmatic progesterone concentration on the day of transfer
annulation 21 days defined when transfer is cancel if endometrial thickness is too thick (\>6-7mm), when spontaneous ovulation is found with progesterone plasmatic increase and corpus luteum is seen by sonography or when unpredictable events occur (infections, ZIKA suspicion, endometriosis crisis, bad observance...). Annulation could be decided by biologist in case of embryo's lysis or bad quality seen after thawing.
satisfaction evaluated by anonymous survey the day of transfer 1 month evaluated by anonymous survey the day of transfer
spontaneous pregnancy loss 12 weeks Including early and late pregnancy losses
plasmatic estradiol concentration on the day of transfer 21 days plasmatic estradiol concentration on the day of transfer
endometrial thickness 21 days sonographic measurement of endometrial thickness on the day of transfer
