Sertoli cells from non-obstructive azoospermia and obstructive azoospermia patients show distinct morphology, Raman spectrum and biochemical phenotype.
STUDY QUESTION Are there differences in the morphology, spectrum and biochemical phenotype between Sertoli cells from non-obstructive azoospermia (NOA) patients and those from obstructive azoospermia (OA) patients with normal spermatogenesis? SUMMARY ANSWER Sertoli cells from NOA patients are distinct from those from OA patients in terms of morphological features, Raman spectrum and phenotype...
متن کاملP-34: Expression of Toll-like Receptor2-3 Genes in Sertoli Cells of Patients with Azoospermia
Background: Toll-like receptors (TLRs) constitute a major part of innate immunity, which can distinguish pathogen associate molecular pattern. Sertoli cells create a special immunological niche that protects somniferous tubules from auto antigens and pathogens. These cells are the only somatic cells in somniferous that protect testis cells against pathogens. The purpose of this study was to eva...
متن کاملSurgical management of nonobstructive azoospermia
Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist. In the era of in vitro fertilization with intracytoplasmic sperm injection, surgical sperm extraction techniques can afford men with NOA biologic paternity. To provide a ...
متن کاملControversies in the management of nonobstructive azoospermia.
The fertility potential of patients with nonobstructive azoospermia (NOA) depends on sperm extraction from the tissue sample and then in vitro fertilization with intracytoplasmic sperm injection (IVF/ICSI). Unfortunately, there is no consensus regarding predictors that can identify nonobstructive azoospermic men with a potentially high yield at the time of sperm extraction. This article analyze...
متن کاملObstructive and Non-Obstructive Azoospermia
Azoospermia is defined as the complete absence of spermatozoa upon examination of the semen [including capillary tube centrifugation (CTC), strictly confirmed by the absence of spermatozoa issued in urine after ejaculation]. The presence of rare spermatozoa (<500.000/ml) in seminal fluid after centrifugation is called "cryptozoospermia". The complete absence of spermatozoa should be confirmed w...
