Protocol summary

Study aim
Determining the effect of PRP on the process of spermatogenesis in azoospermic patients
Design
Clinical trial without control group, before and after, without blinding, randomized, phase 3 on 100 patients
Settings and conduct
This study will be conducted only on a group of 20 NOA patients referred to Royan Institute with negative mTESE history. There is no control group and blinding will not be done. Also, in the first phase, the study will be conducted as a pilot, and after the data analysis, if the statistical analysis is significant - taking into account the primary goal of observing the treatment in these patients - the next phase of the study will be conducted. After receiving the permission of the ethics committee in the research, the research samples will be selected based on the study entry criteria and after obtaining informed consent to participate in the research, they will be subjected to intratesticular PRP injection.
Participants/Inclusion and exclusion criteria
Men over 18 years with a history of non-obstructive azoospermia and at least one failed mTESE will be included in the study.
Intervention groups
After receiving the permission of the ethics committee in the research, the research samples after obtaining informed consent to participate in the research, they will be subjected to intratesticular PRP injection. To prepare PRP, the PRP kit (Stem cell motivation kit, ROOYAGEN, Iran) will be used.
Main outcome variables
Comparing the effect of PRP on LH hormone levels after PRP injection Comparing the effect of PRP on FSH and testosterone levels after PRP injection Comparison of the effect of PRP on individual Semen Analysis after PRP injection Comparison of the effect of PRP on the outcome of mTESE, after PRP injection Determination of fertilization rate, clinical pregnancy (hCG positive), stable implantation (more than 8 weeks) if sperm is found

Intervention groups

1

Description
Intervention group: Patients with non-obstructive azoospermia with a history of at least one mTESE failure. After receiving the permission of the ethics committee in the research, the research samples are selected based on the criteria for entering the study and after obtaining informed consent to participate in the research, they will be subjected to intratesticular injection of PRP. In order to prepare PRP, from the PRP kit ( Stem cell motivation kit, ROOYAGEN, Iran) will be used. The duration of PRP preparation will be less than 45 minutes. Prepared PRP is injected into the spermatic cord or into the interstitial space using a 5 ml syringe. In the third month after testicular PRP, gonadotropin stimulation in the patient's wife begins on days 2 to 4 of the menstrual cycle. Sperm extraction with the mTESE method will be performed at the same time as the egg retrieval day in order to use fresh sperm cells. In the first stage, 3 months after PRP injection into the testicles, sperm analysis will be checked in patients. The second stage will be 6 months after the injection. According to the obtained results, the sperm is injected into the cytoplasm of the egg by assisted reproductive techniques (ICSI) and fertilization takes place.
