Effects of Ejaculation-to-Analysis Delay on Levels of Markers of Epididymal and Accessory Sex Gland Functions and Sperm Motility
Biochemical markers morphology semen analysis viability
2008/12/24
This study aimed to examine the association between the interval from ejaculation to analysis and epididymal and accessory sex gland function in relation to sperm motility. Ejaculates from 1079 men ...
Sonic Hedgehog Pathway Inhibition Alters Epididymal Function as Assessed by the Development of Sperm Motility
Hedgehog genes epididymal regulation posttesticular sperm development
2008/12/23
The sonic hedgehog (Shh) signaling pathway plays a role in pattern orientation in the developing embryo and has been shown to be required for development of the prostate and external genitalia. Rece...
The Stimulatory Role of Estrogen on Sperm Motility in the Male Golden Hamster（Mesocricetus auratus）
Estrogen immunization gonadotropin
2008/12/23
To clarify the physiological roles of estrogens in the regulation of sperm motility in the golden hamster, two different approaches were used. In the first experiment, silastic tubes containing ei...
Sperm Motility in Men With Spinal Cord Injuries Is Enhanced by Inactivating Cytokines in the Seminal Plasma
Infertility ejaculation semen IL1-ß IL6 TNF-
2008/12/22
The goal of this study was to determine whether inactivating specific cytokines in seminal plasma improves sperm motility in men affected by spinal cord injury (SCI). For this purpose, we used mon...
Role of Nitric Oxide Concentrations on Human Sperm Motility
Male infertility spermatozoa motility asthenozoospermia
2008/12/22
Nitric oxide (NO) is a free radical generated from the oxidation of L-arginine to L-citrulline by 3 isoforms of reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent NO synthases. Se...
Effect of Simulated Microgravity on Testosterone and Sperm Motility in Mice
Tail suspension space simulated weightlessness testicular function spermatogenesis mouse
2008/12/19
We examined changes in the serum testosterone level and in sperm in the testis and epididymis by using tail-suspended mice, which are a simulation model of the body fluid shift in space, to evalua...
Tales From the Tail：What Do We Really Know About Sperm Motility?
Tales Tail Know Sperm Motility
2008/12/19
Male factor infertility is a significant problem in humans and domestic animals (Lunenfeld and Insler, 1993). In humans, it is estimated that 20% of couples are infertile and that, in 50% of these cas...
Sperm Mitochondrial Mutations as a Cause of Low Sperm Motility
Infertility oligoasthenoteratozoospermia mitochondrial DNA short tandem repeats
2008/12/19
We report the unique case of a 28-year-old man who, in spite of having a varicocele and a sperm concentration of 5 million/mL, of which 10% were motile and 20% had normal forms (oligoasthenoteratozo...
Spinal Cord Contusion Impairs Sperm Motility in the Rat Without Disrupting Spermatogenesis
Spinal cord injury cAMP sperm
2008/12/19
Our previous studies demonstrated various abnormalities in spermatogenesis after spinal cord injury (SCI) in cord-transected rats. In this study, we examined whether abnormalities in spermatogenes...
