About this study

Official title: The Effects of Intratesticular PRP Injection

The study will be conducted in men with a diagnosis of non-obstructive azoospermia or cryptozoospermia after obtaining written informed consent. The diagnosis of azoospermia and cryptozoospermia will be based on two semen analyses performed at least 15 days apart, followed by a documented micro testicular sperm extraction (TESE). A detailed history will be obtained, physical examination and laboratory evaluation will be performed prior to treatment. In physical examination, testicular volumes will be evaluated using an orchiometer. Serum FSH and testosterone values will be determined. PRP will be prepared by centrifugation of approximately 20 ml autologous blood obtained by phlebotomy. PRP (3 ml) will be administered into the seminiferous tubule or interstitial space of each testis. Sperm analysis, testicular volume (using orchiometer), serum FSH and testosterone levels will be reevaluated at 8 weeks post-procedure. Micro TESE will performed on the third month after PRP procedure.

Read the detailed description

Platelet-rich plasma (PRP) is a unique autologous agent derived from blood that is rich in growth factors, cytokines, and hormones; it has been reported to reduce oxidative stress and reactive oxygen species generation and upregulate the expression of various antioxidant enzymes. PRP is used in a variety of clinical applications in cell therapy. Based on World Health Organization guidelines, azoospermia is diagnosed when the absence of sperm is observed in two semen samples. Based on World Health Organization (WHO), cryptozoospermia is diagnosed when spermatozoa cannot be observed in a fresh semen sample; however, it is found after an extended centrifugation and microscopic search. All patients require a clinical work-up with physical examination, endocrine evaluation (follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone) and genetic analysis. Scrotal and transrectal ultrasounds will be performed as indicated. Platelet-rich plasma (PRP), with its rich growth factor composition, has proven beneficial in regenerative therapy. The potential therapeutic role of PRP has not been studied in testis for non-obstructive azoospermia and cryptozoospermia. The investigators will investigate sperm parameters in non-obstructive azoospermic and crypotozoospermic patients treated with PRP.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PRP injection into at least one testisBiological

    Autologous blood obtained from peripheral vein will be used to prepare PRP following standard protocols. PRP injection will be performed under local anesthesia. Sperm analysis, testicular volumes (using orchiometer), serum FSH and testosterone measurements will be re-evaluated at 8 weeks post-procedure. On the third month after the procedure, presence of spermatozoa will be reassessed in micro testicular sperm extraction (TESE) material.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. sperm formation

    Number of participants with testicular PRP treatment as assessed by testicular sperm extraction, change from azoospermia or cryptozoospermia to presence of sperm during TESE procedure

    Measured: 6 months

Secondary outcomes (1)
  1. IVF outcomes

    Number of participants with testicular PRP after TESE as assessed by number of clinical pregnancies, change in the clinical pregnancy rates with IVF treatment.

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing PRP injection into at least one testis in people with Azoospermia, Nonobstructive, run by Acibadem University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Nov 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

sperm formation (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04237779, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Nov 2020; AzTrials last refreshed its copy on 8 Nov 2026.
