Human Reproduction, 2019
STUDY QUESTION Are there genetic variants that can be used for the clinical evaluation of azoospermic men? SUMMARY ANSWER A novel homozygous frame-shift mutation in the MEIOB gene was identified in three azoospermic patients from two different families.

Clinical study of azoospermia

International Journal of Andrology, 1994
SummaryThis study evaluated how many patients with azoospermia might have fertility potential using assisted conception techniques. A total of 102 male patients with aioospermia were included in the study. Thirteen patients had sex chromosomal abnormalities. Testicular biopsy performed in the other 89 patients showed incomplete spermatogenesis in 47 of

The Management of Azoospermia

British Journal of Urology, 1978
Summary— Azoospermia in the presence of a normally funcitioning testis and a normal vasogram has been thought to be due to an obstruction in the epididymis between the body and the head. However, bypass operations have been singularly unsuccessful except when there was evidence of past inflammation causing ...

Testicular cytology in azoospermia

Diagnostic Cytopathology, 1993
AbstractTwo hundred‐seventy‐five azoospermic mates were subjected to fine‐needle aspiration (FNA) cytologic study of testis with the aim of determining the cause of azoospermia; 534 aspirates from these patients were classified as follows: normal spermatogenesis (162), hypospermatogenesis (mild, moderate, or severe, 226), absence of spermatogenesis ...
