This is a prospective, multicenter, randomized, double-blind, placebo-controlled, two parallel group of patients, Phase IIIb clinical study to test the efficacy and safety of adding low-dose hCGs in a short protocol with GnRH agonist and ovarian stimulation with recombinant FSH (rFSH) from the onset of the follicular phase and throughout the duration of stimulation in enrolled women to the increase in the rate of clinical pregnancies.
Main end point will be the rate of clinical pregnancy (positive heart rate at 7 weeks of gestation in the ultrasound), while secondary endpoints will be
- The number of follicles (> 11,> 14,> 18 mm) on the day of triggering with hCG
- The thickness of the endometrium on the day of follicular maturation
- Live birth rates
- Automatic abortion rates (loss of pregnancy after positive heart function up to 20 weeks of gestation)
- The rate of ongoing pregnancy (positive heart function after 12 weeks of gestation),
- The percentage of ovarian hyperstimulation syndrome (after triggering) with hCG for the next 2 weeks
- The rate of multiple pregnancy.
Participants will be randomly divided into two groups: the intervention group (Group 1) and the control group (Group 2). Randomization will be done using sealed envelopes marked "Group 1" and "Group 2". The randomization list will be prepared centrally for the four participating clinics (research centers) and there will be a "stratification" per center, per 30, respectively, and will be shared among the participants.
"Group 1" will indicate the application of the protocol by adding hCG with the initiation of controlled ovarian stimulation protocol for IVF / ICSI with rFSH, and "Group 2" will indicate the application of the conventional protocol without the addition of hCG .
Each patient's assignment to a treatment group will be made by calling the unit's midwife who will have 2 envelopes with the above indications and who will not be present when the pair is informed by 2 members of the research team.

Experimental: Group 1 [HCG (+) group]
"Group 1" will indicate the application of the protocol by adding hCG with the initiation of standard GnRH agonist protocol for IVF / ICSI with rFSH
the addition of hCG (Pregnyl®, MSD Greece) will begin with the administration of gonadotrophin at a dose of 100 IU per day, administered subcutaneously, and will continue until the administration of hCG for follicular maturation.
Other Name: Pregnyl
Placebo Comparator: Group 2 [placebo]
"Group 2" will indicate the application of the standard GnRH agonist protocol without the addition of hCG, but placebo, instead
100IU per day containing N/S 0.9% will be injected
- number of transferred embryos [ Time Frame: 21 days after the beginning of ovarian stimulation ]number of high quality transferred embryos at day 3
- The rate of clinical pregnancy [ Time Frame: 7 weeks after the initiation of treatment ]Positive heart rate at 7 weeks of gestation in ultrasound
- Number of follicles [ Time Frame: 2 weeks after the initiation of treatment ](> 11,> 14,> 18 mm) on the day of triggering with hCG
- The thickness of the endometrium [ Time Frame: 2 weeks after the initiation of treatment ]On the day of follicular maturation (triggering) with hCG
- Automatic abortion rates - miscarriage [ Time Frame: up to 20 weeks of gestation ](Lss of pregnancy after positive heart function up to 20 weeks of gestation
- The percentage of ovarian hyperstimulation syndrome [ Time Frame: 2 weeks after the hCG triggering ]After triggering with hCG
