Testicular Biopsy: Sperm Antibodies

Fertility and Sterility, 1975
No circulating sperm-agglutinating or sperm-immobilizing antibodies were demonstrated in oligospermic or azoospermic men up to 14 days following bilateral testicular biopsies. Possible reasons for this lack of antigen-antibody response are discussed.

According to the European Association of Urology (EAU) guidelines, a therapeutic testicular biopsy (for testicular sperm extraction, TESE) is indicated (1) in the case of obstructive aszoospermia (OA), indicated by normal testicular volume, normal FSH (

Quantitative Evaluation of Testicular Biopsies in Varicocele

Fertility and Sterility, 1978
Testicular biopsies from 81 patients with varicocele were evaluated by the score count method. Thirty-two patients sought treatment for infertility. Bilateral biopsies were performed in 47. Spermatogenesis was generally reduced in patients with varicocele, but there was no difference between the right and left tests.

The Diagnostic and Prognostic Significance of the Testicular Biopsy

Andrologia, 2009
The authors present the histological features of the testes in 1,609 cases of male sterility. In 485 cases (30.1%), histological changes were found, which did not warrant treatment. The histologic pattern of the testes was normal in only 39% of the cases of azoospermia; and only these patients were qualified for surgery, consisting of ...

The Value of Testicular Biopsy in Patients with Varicocele

Journal of Urology, 1986
With the use of semi-thin sections of 88 testicular biopsies from 44 patients, we were able to separate a relatively uniform group of patients with idiopathic left varicocele and infertility into 4 groups with different pathophysiological conditions. Group 1 patients had atrophy of the Leydig cells, decreased Leydig cell ratio, low plasma testosterone,

Testicular Biopsy and Vasography

1997
Testis biopsy is performed to identify the quality of spermatogenesis in patients who may have obstructive male infertility or to identify the presence of testicular sperm cells, which may be aspirated and used for intracytoplasmic sperm injection (ICSI).

Testicular biopsy: an update

Current Diagnostic Pathology, 1998
Testicular biopsy has undergone several modifications during the past 30 years; and with the increasing use of fine needle aspiration (FNA) biopsy, we have seen changes in its indications, technique and interpretation. Currently, there is no agreement on systematic reporting of testicular biopsies.
