The incidence of spermatic granulomas and their relation to testis weight after vasectomy and vasovasostomy in Lewis rats
spermatic granulomas testis weight vasectomy vasovasostomy Lewis rats
2009/2/23
The occurrence of spermatic granulomas of the vas deferens was studied in Lewis rats at intervals up to 7 months after vasectomy or vasectomy followed 3 months later by vasovasostomy. The incidence ...
Pulsatile secretion of gonadotropins and prolactin in male marathon runners. Relation to the endogenous opiate system
gonadotropin prolactin endurancetraining marathon runners pulsatile secretion opiates
2009/2/20
We tested the hypothesis that sustained, strenuous physical training alters the neuroendocrine regulation of pulsatile gonadotropin and/or prolactin secretion in men. Blood was sampled at 20-minute ...

2009/2/18
The presence of different titers and types of sperm-agglutinating antibodies in serum and seminal fluid as well as the immunoglobulin content of the fluid were evaluated in 93 men with azoospermia...
A Possible Relation between Elevated FSH Levels and Leydig Cell Dysfunction in Azoospermic and Oligospermic Men
follicle-stimulating hormone luteinizing hormone testosterone oligospermia
2009/2/18
Plasma testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels were measured in the male partners of 69 infertile couples and in 260 allegedly fertile men requesting va...
Temporal relation between leptin and various indices of sexual maturation in the male rat
Puberty adipose tissue testosterone gonadotropins
2009/2/18
Recent studies in humans and rhesus monkeys have suggested the possibility that the adipose tissue hormone leptin has a stimulatory and/or permissive effect on the onset of puberty in the male. We...
The relation between reactive oxygen species and cytokines in andrological patients with or without male accessory gland infection
IL-ia lL-6 IL-8 HGF spermatozoa male infertility
2009/2/17
The presence of various cytokines, namely hepatocyte growth factor (HGF), interleukin-1 receptor antagonist (IL-1 RA), and interleukins (IL-1 alpha, IL-6, and IL-8), as well as the production of rea...
Lipid transfer activity in human follicular fluid：relation to human sperm capacitation
sperm capacitation acrosome reaction lipid transfer cholesteryl ester
2009/2/6
A potentially important event during sperm capacitation is the loss of sperm membrane cholesterol. Although the exact mechanisms mediating this loss are not known, albumin and high density lipopr...
Morphology of testicular spermatozoa obtained by testicular sperm extraction in obstructive and nonobstructive azoospermic men and its relation to fertilization success in the in vitro fertilization-intracytoplasmic sperm injection system
Morphology testicular spermatozoa testicular sperm extraction azoospermic men
2008/12/26
The aim of the present study was to evaluate the morphology of testicular spermatozoa by 3 different determinants. Sperm cells were obtained and their morphology was evaluated from 27 testicular spe...
