Sertoli cell-only syndrome
ثبت نشده
چکیده
Sertoli cell-only syndrome is defined by the complete absence of germ cells in testicular tissues and always results in male infertility. Germ cells give rise to next stages of spermatogenesis which is the process of sperm formation. They are normally attached to Sertoli cells forming together so called seminiferous tubules which form testicular tissue. If there are only Sertoli cells, then no sperm can be produced . The aetiology often remains unknown, yet it is proven that genetic faults takes part in development of this disorder.

One hundred one azoospermic males were subjected to fine needle aspiration cytology (FNAC) of the testis and 11 of them underwent testicular biopsy as well. In 99 cases, the aspiration was adequate for classifying into different categories, which are as follows: Sertoli cell only syndrome (46), normal spermatogenesis (27), hypospermatogenesis (10), tubular/peritubular sclerosis (10) and maturat...
