The prevalence of chronic infections of the nasal sinuses and the lung (chronic sinopulmonary disease) was investigated in 33 Chinese patients with obstructive azoospermia who were compared with 32 pa...
Free carnitine in human semen originates predominantly in the epididymis. The role of carnitine in the evaluation of different forms of obstructive azoospermia was studied in 42 patients. In 14 of t...
A cup-shaped silicon prosthesis was developed to treat patients with excretory azoospermia and chemical management of the aspirated spermatozoa was attempted prior to cervical insemination of the wi...
Azoospermic semen was obtained from 39 vasectomized men and 93 patients consulting for infertility. The latter underwent bioclinical investigations including measurement of plasma FSH and testicular...
We previously reported that the HLA-A33, -B13, and -B44 antigens, which are major histocompatibility complex class I molecules, are involved in the susceptibility of nonobstructive azoospermia in ...
Because androgens are required for normal spermatogenesis, we are investigating abnormalities in the androgen receptor as a possible cause of impaired spermatogenesis in patients with idiopathic mal...
Seven Georgian male soldiers (19-25 years old) had accidentally been exposed to radiation by Cs-137 between April 1996 and May 1997. No information about the exact time and duration of exposure was ...
Seminal plasma is a potential source of biomarkers for many disorders of the male reproductive system. The identification and characterization of proteins in the seminal plasma by using two-di...
Although semen quality often fluctuates over time, it is relatively uncommon for a patient with documented fertility to develop azoospermia in the absence of an identifiable causative factor. This is ...
Three sperm-counting methods were compared within and between 3 centers to determine the sensitivity and reproducibility of assessing low sperm concentrations. Two methods were performed by phase cont...
The testicular sperm from biopsy and frozen/thawed tissue are frequently immotile. The purpose of our retrospective study was to assess the effect of short exposure of testicular samples with only i...
To compare the efficacy of 2 sperm-retrieval procedures, testicular sperm extraction (TESE) and testicular sperm aspiration (TESA), during the same procedure using the same subjects as their own con...
Clomiphene citrate is a well-established agent that has been empirically used in cases of idiopathic oligospermia. Clomiphene increases endogenous gonadotropin-releasing hormone secretion from the h...
The aim of this comparative clinical study was to examine whether the fertilizing potential of frozen-thawed testicular sperm in the most severe cases of hypospermatogenesis is reduced compared with...
The testis of patients with nonobstructive azoospermia (NOA) harbors sperm in approximately 30% to 60% of cases. Use of an operating microscope has been shown to result in better sperm retrieval rat...
