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.

Interventions

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

DRUGEstradiol 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.

annulation21 daysdefined 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.
