Plain English summary of protocol

Background and study aims
Progesterone administration is considered an essential therapy for luteal phase support in patients undergoing in-vitro fertilization (IVF) technologies This study aims to compare the administration of a combined protocol of vaginal gel progesterone (90 mg/daily) and oral dydrogesterone (20 mg/daily), with the administration of micronized vaginal progesterone alone (800 mg daily) to support the luteal phase during embryo implantation in patients undergoing in vitro fertilization.

Who can participate
Infertile patients undergoing standard in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) treatment at One Day Medical Center IVF Unit

What does the study involve
Ovarian stimulation:
All the patients will undergo a mild ovarian stimulation protocol:
Subcutaneous injections of recombinant follicle-stimulating hormone (rFSH) will be started at a dose of 75-150 IU (international unit). Growing ovarian follicles will be detected and measured using ultrasonography at two-day intervals. Estradiol blood level will be measured at two days intervals. Subcutaneous injections of Gonadotropin-releasing hormone antagonist (GnRH ant) (0.25 mg/day) will be administered when the leading follicle measures 14 mm. The rFSH dose will be adjusted when necessary according to the follicular size and estradiol level. Final oocyte maturation will be induced by subcutaneous injection of a dose of 10,000 IU of Human Chorionic Gonadotropin (hCG).

Oocyte recovery and embryo transfer
Oocyte retrieval will be carried out at 34-36 hours after hCG injection. Recovered oocytes will be inseminated by standard IVF or ICSI. Up to 3 embryos will be transferred into the patient's uterus on day three after the oocyte insemination.

What are the possible benefits and risks of participating?
Benefits: the applied supplementation therapy for luteal phase support after embryo replacement could increase the pregnancy and live birth rates.
Risks: the applied supplementation therapy for luteal phase support after embryo replacement could reduce the chance of pregnancy and live birth.

Study objectivesTo compare the administration of a combined protocol of progesterone vaginal gel and oral dydrogesterone, with the administration of micronized vaginal progesterone alone for luteal phase support in patients undergoing GnRH antagonist-mild stimulation regimen
Ethics approval(s)

Approved 10/12/2016, One Day Ethics Commission (Via Attilio Ambrosini 114, Roma, 00147, Italy; +39 (0)645212028; amministrazione@onedaymedicalcenter.it), ref: ethics12-2016

InterventionAll the patients are going to have a mild ovarian stimulation protocol:
rFSH will be started at a dose of 75-150 IU on the base of AMH level. GnRH antagonist (0.25 mg/day) will be administered when the leading follicle measures 14 mm. The FSH dose will be adjusted when necessary according to the follicular size and estradiol level. Final oocyte maturation will be induced by a dose of 10,000 IU of hCG. Recovered oocytes will be inseminated by standard IVF or intracytoplasmic sperm injection (ICSI). Up to three embryos will be transferred on day 3 after oocyte insemination.

Randomization will be performed using a computer-generated random assignment schedule for each patient. Sealed and numbered envelopes will be used to conceal the treatment allocation until randomization. On the day of oocyte recovery, the patients will be randomized into two groups: Group A will receive vaginal administration of capsules of micronized progesterone (800 mg/day) for luteal phase support; Group B will receive a combination of vaginal administration of a gel of micronized progesterone (90 mg/day) and oral dydrogesterone 10 mg twice a day for luteal phase support. The duration of the treatment is 14 - 21 days; follow-up will be around 9 months for each patient, from the established pregnancy to the delivery.

Primary outcome measureClinical pregnancy measured using a blood test to evaluate the level of human chorionic gonadotropin (hCG), which indicates the eventual embryo implantation and pregnancy, 14 days after embryo replacement in the patient's uterus
Secondary outcome measuresEmbryo implantation rate measured using ultrasonography at 4 weeks following a positive hCG test to confirm the clinical pregnancy
