    Intervention group:low-power laser treatment with Diodes ir AIGaAs laser from New Age Company with the following specifications and without charge and after obtaining informed consent from the patient: Power: 230 V Frequency: 50/60 Hz Wavelength: 850 nm Treatment sessions with Low power laser consists of 6 sessions (16 minutes each session) which is performed during the first 2 weeks of the menstrual cycle and every other day except for holidays, and in the next cycle after the laser treatment, the embryo transfer cycle begins. The laser device is directly contacted with the skin of the suprapubic area in the anatomical location of the uterus (diagnosed by abdominal ultrasound) and after emptying the bladder, and during the treatment of the uterus by placing a sterile dummy manipulator in the posterior fornix of the vagina (similar to the generator and made with vibril and latex coating with a diameter of 3 cm) is directed to the front so that the maximum laser energy reaches the branches of the endometrial vessels.

Randomization description
Block randomization Individual Randomization tool: clinic supervisor How to make a random sequence: blocks of 2 alleles of size 4 (AABB, ABBA, ABAB, BAAB, ...) We decided to assign A to the intervention group (laser) and B to the control group. First, the qualified sample is selected based on the entry and exit criteria, and then it is placed in subgroup A or B according to the constructed blocks. This process continues until 15 items are completed in each group. For randomization, we used the following site to determine the sequences: https://www.sealdenvelope.com/simple-randomiser/v1/lists
