Autologous Adipose-Derived Adult Stromal Vascular Cell Administration for Male Patients With Infertility

Efficiency Evaluation of Adipose-Derived Adult Stromal Vascular Cells in Patients With Spermatogenesis Disorders.

Severe Oligospermia (oligozoospermia) refer to semen with a low concentration of sperm and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility that affect Male fertility. The purpose of this study is to assess the ability of Autologous Adipose-Derived Adult Stromal Vascular Fraction (SVF) cells to stimulate Sertoli and spermatogonia cells and affect male fertility.

This is an open-label study to evaluate efficiency of administration of Autologous Adipose-Derived Adult Stromal Vascular Fraction (SVF) in the testis in patients with oligospermia and azoospermia.

Forty men with several form oligozoospermia and azoospermia will be recruited for the study. 20 patients with same diagnosis served as a control with standard medications.Other patients -10 with oligospermia and 10 with azoospermia will receive standard medication and SVF injections.

The diagnosis of Azoospermia (Oligospermia) will be established on the basis of two and more semen analysis evaluations done at separate occasions and detailed history taking, physical examination and investigations (blood tests include hormon levels as testosteron. follicle stimulating hormone (FSH), luteinizing hormone (LH). karyotyping and testosterone levels, and may include testicular biopsy or transrectal ultrasound if indicated.

This study affect only Pretesticular and Testicular forms, without chromosomal aberration. SVF can produce a lot of cytokines ( as EGF, FGF, NGF, PDGF, VEGF, IGF, GMCSF, GCSF, TGF, Erythropoetin, TPO, BMP, HGF, GDF, Neurotrophins, MSF, SGF, GDF and growth factors) moreover the microvesicles and exosomes released by this cells can prevent cells from apoptosis and stimulate regenerative process of surrounding tissues and cells.

SVF will be transplanted by an andrological surgeon through a standard surgical approach. Subjects will be monitored frequently for a total of one year after cell injection.
