Different testosterone and LH relationships in infertile men
Different testosterone LH relationships infertile men
2009/2/23
In both man and animals, changes in Leydig cell structure and function accompany seminiferous tubule damage. In this study of 1745 men attending an infertility clinic, 14% of men with elevated lev...
The presence of a motility inhibitor within spermatozoa may explain the poor sperm motility of some infertile men
motility inhibitor spermatozoa poor sperm motility infertile men
2009/2/23
The presence of motility inhibitors in seminal plasma and within spermatozoa from control and infertile men with poor sperm motility was investigated using demembranated reactivated human spermatozo...
Prognosis of subfertility in men with corrected or uncorrected varicocele
subfertility men with corrected uncorrected varicocele
2009/2/23
To evaluate whether correction of varicocele improves fertility, pregnancy rates were compared in 115 varicocele patients consulting for infertility and having oligozoospermia, asthenospermia, or te...
Accessory sex gland function in normal young（20-25 years）and middle-aged（50-55 years）men
Accessory sex gland function normal young（20-25 years） middle-aged（50-55 years）men
2009/2/23
A comparison of various parameters of prostatic and vesicular secretory function was made between the seminal plasma of young (20-25 years; n = 23) and middle-aged (50-55 years; n = 19) male volunte...
Spectrum of the pulsatile characteristics of LH release in normal men
pulsatile characteristics LH release normal men
2009/2/23
To assess the spectrum of LH pulse characteristics in normal men, blood samples from 36 individuals were drawn at 20-minute intervals for 8 hours. The subsequent immunoactive LH concentrations were ...
Possible significance of transferrin levels in seminal plasma of fertile and infertile men
seminal transferrin FSH fertility man
2009/2/23
Human seminal plasma contains large amounts of transferrin, which is a protein secreted mostly by Sertoli cells. It has been suggested that the concentration of transferrin may serve as a possible c...
Whole cell and nuclear androgen uptake in skin fibroblasts from infertile men
Whole cell nuclear androgen uptake skin fibroblasts infertile men
2009/2/23
In order to reexamine the hypothesis that a high percentage of infertile men with oligo/azoospermia have androgen resistance due to androgen receptor abnormalities, both whole cell and nuclear uptak...
Stagnation of blood in the microvasculature of the affected and contralateral testes of men with short-term torsion of the spermatic cord
Testis germ cells microvasculature electron microscopy torsion
2009/2/23
Bilateral testicular biopsies from four men with a short duration (3 hours 10 minutes to 4 hours 30 minutes) of unilateral spermatic cord torsion and testicular biopsies from six men with irreversib...
Stimulation of sperm production by human chorionic gonadotropin after prolonged gonadotropin suppression in normal men
sperm production human chorionic gonadotropin prolonged gonadotropin suppression normal men
2009/2/20
The precise hormonal milieu required for quantitatively normal spermatogenesis in man is unclear. The authors previously have shown that both supraphysiologic dosages of human chorionic gonadotropin...
Stagnation of blood in the microcirculatory vessels in the testes of men with varicocele
blood microcirculatory vessels men varicocele
2009/2/20
This study reports on the stagnation of blood within the microcirculatory vessels of the testes of patients with varicocele. Both fine structural and quantitative studies were carried out on testi...
