About this trial
To evaluate whether single euploid embryo transfer in NC without routinely administered LPS is non-inferior to NC with routinely administered LPS.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Age: 18 to 40 years
Regular ovulatory cycles
Availability of at least one euploid embryo after Trophectoderm biopsy for PGT-A on day 5 or day 6
Detection of ovulation by P4 rise > 1.0 ng/ml after LH surge
Disqualifiers
History of repeated pre-menstrual spotting
Factors affecting the implantation through anatomical changes of the uterus / ovaries or the tubes (adenomyosis, Asherman syndrome, endometriosis, uterine fibroids / polyps, isthmocele with intracavitary fluid presence, hydrosalpinx….)

Treatments tested in this trial
Transvaginal ultrasound
Diagnostic testIntermittent transvaginal ultrasound throughout the cycle to monitor follicular growth
Serial serum LH, E2, P4
Diagnostic testSerial measurements of serum Luteinizing Hormone (LH), Estradiol (E2) and Progesterone (P4 )levels throughout the cycle to determine ovulation. LH-surge is identified when a rise of 180% above the previous level occurred and ovulation is confirmed with a decrease in E2 concentration, and a rise of progesterone level to ≥ 1.0 ng/ml (Irani et al., 2017).
Progesterone 100 Mg Vaginal Insert
DrugOn day of ET procedure, to administer 200 mg of vaginal progesterone and increase to 300 mg/day from the day after the ET onwards until the pregnancy test. In case of an implantation, vaginal P4 will be continued until 7 weeks of pregnancy
Serum P4 day of ET - Control Group
Diagnostic testSerum P4 will be drawn before starting LPS in form of vaginal progesterone on the day of ET procedure
Serum P4 day of ET - Study Group
Diagnostic testSerum P4 will be drawn when study group participants are admitted to the clinic for the ET procedure.
Embryo transfer
Procedure/SurgeryThe procedure in which embryo is placed in the uterus.
Serum hCG 10 days after ET
Diagnostic testPregnancy will be confirmed / excluded by measurement of serum hCG 10 days after ET procedure and a level of \> 15 IU will be regarded as positive result. The definitions of biochemical, ectopic, clinical and ongoing pregnancy follow the ICMART criteria (Zegers-Hochschild, 2006)
Serum P4 10 days after ET
Diagnostic testSerum P4 will be drawn on day 5 or day 6 after the ET procedure and together with the hCG 10 days after ET procedure
Treatment groups
Trial outcomes
Primary outcomes
Implantation rate
Number of embryos which have produced ultrasonographic evidence of an intrauterine gestational sac per the total number of embryos transferred into the uterine cavity (Zegers-Hochschild et al., 2009).
Clinical pregnancy rate
hCG \> 15 Iu/ml and ultrasound confirmation of a gestational sac
Live birth rate
Number of deliveries that resulted in a live born neonate, expressed per 100 embryo transfers (Zegers-Hochschild et al., 2009)
Serum P4 levels on ET day
Progesterone level on the day of embryo transfer
