To investigate the efficacy of dydrogesterone 30 mg compared to micronized vaginal progesterone 800 mg daily for luteal phase support in hormone replacement therapy frozen embryo transfer cycles, as confirmed by visualization of fetal heart activity by pelvic ultrasound assessment of ongoing pregnancy at 12 weeks of gestation.
A randomized controlled trial comparing dydrogesterone 30 mg versus micronized vaginal progesterone 800 mg daily for luteal phase support in hormone replacement therapy frozen embryo transfer cycles. Patients will undergo an embryo transfer in a hormone replacement therapy cycle using Progynova 2 mg three times daily until an endometrium thickness of at least 7 mm is reached. Afterwards two different luteal phase supplementation methods will be compared. The primary outcome of the study is ongoing pregnancy at 12 weeks of gestation. We will also investigate other prenatal and neonatal outcome factors as well as patients satisfaction and safety of dydrogesterone.

Ongoing pregnancy
visualisation of a fetal heart activity via pelvic (vaginal/abdominal) ultrasound examination at 12 weeks of gestation.
Time frame: 12 weeks
Live birth rate
as the birth of a live newborn after 22 weeks of gestation
Time frame: 22-42 weeks
Time of delivery
time of delivery (gestational week) will be confirmed (by calculation from date of embryo transfer)
Time frame: follow-up time of 30 days after delivery
Incidence of Treatment-Emergent Adverse Events
Tolerability and safety will be asses during the whole study period. Adverse events will be considered as unexpected if the nature, seriousness, severity or outcome of the reaction(s) is not consistent with the reference information. The expectedness of adverse events for the medications used in this study is detailed in the reference safety information in the current summary of product characteristics (SmPCs) issued in the participating countries. All serieus suspected unexpected serious adverse drug reactions (SUSARs) will be subject to expedited reporting. The investigator is responsible for submitting reports of SUSARs to the appropriate national regulatory authorities within the required reporting period. The investigator is responsible for notifying the IECs/IRBs in writing of the SUSARs within the required reporting timelines. Copies of the notification will be maintained by the investigator in the study documentation files.
Time frame: follow-up time of 30 days after delivery
Patient reported outcome
Questionnaire (using the Treatment Satisfaction Questionnaire of Medication (TSQM)) and recording information on treatment tolerability and convenience
Time frame: day 12-18 of luteal phase supplementation (pregnancy test) and at 12 weeks gestation

Incidence of newborn adverse events
Newborn wellbeing and safety including congenital malformations will be evaluated after delivery via a telephonic contact with the patient
Time frame: follow-up time of 30 days after delivery
Biochemical pregnancy rate
serum hCG test (\> 25 mIU/ml), without ultrasound evaluation of a pregnancy
Time frame: day 12-18 of luteal phase supplementation (pregnancy test)
Clinical pregnancy rate
assessed by transvaginal ultrasound and defined as the presence of ≥1 gestational sac on examination
Time frame: Day 33-39 of LPS (Verification of pregnancy)
Miscarriage rate
defined as spontaneous loss of a clinical pregnancy before 22 weeks of gestation (where embryo(s) or fetus(es) is/are nonviable and is/are not spontaneously absorbed or expelled from the uterus)
Time frame: 22 weeks
Rate of preterm birth
Delivery before 37 weeks of gestation
Time frame: follow-up time of 30 days after delivery
Rate of pre-eclampsia
Incidence of pre-eclampsia as defined by the defined as the development of hypertension after 20 weeks of gestation together with one or more new-onset conditions: proteinuria, maternal or uteroplacental dysfunctions. Univariate and multivariable regression analysis were performed to control for known or potential PE risk factors, more specifically: body mass index (BMI), African ethnicity, previous history of hypertensive disorders of pregnancy, mean arterial pressure (MAP) at the first prenatal consultation, polycystic ovary syndrome (PCOS) and ovulation disorders, endometrial thickness and oocyte recipients.
Time frame: follow-up time of 30 days after delivery
Occurence of antenatal bleeding, ultrasonographic abnormalities, gestational diabetes, cholestasis
Occurence of antenatal bleeding, ultrasonographic abnormalities, gestational diabetes, cholestasis
Time frame: follow-up time of 30 days after delivery
Implantation rate
assessed by ultrasound and defined as the number of gestational sacs per number of embryos transferred
Time frame: Day 33-39 of LPS (Verification of pregnancy)
Blastocyst development score
using the system developed by Gardner
Time frame: at the time of embryo transfer (visit 2: day 6 of luteal phase supplementation)
Number of cryopreserved embryos
Number of cryopreserved embryos
