Proteomic analysis of seminal plasma from asthenozoospermia patients reveals proteins that affect oxidative stress responses and semen quality.
Asthenozoospermia (AS) is a common cause of human male infertility. In one study, more than 80% of the samples from infertile men had reduced sperm motility. Seminal plasma is a mixture of secretions from the testis, epididymis and several male accessory glands, including the prostate, seminal vesicles and Cowper's gland. Studies have shown that seminal plasma contains proteins that are importa...
متن کاملPhospholipids of bovine spermatozoa and seminal plasma.
Spermatozoal and seminal plasma lipids of fourteen individual bulls were separated by column chromatography into neutral lipid and several phospholipid fractions. Elution progress was monitored by thin-layer chromatography. Each phospholipid constituent was determined by phosphorus analysis. Total lipid, cholesterol and plasmalogen contents were determined. The fatty acids and aldehydes of the ...
متن کاملEffect of heterologous seminal plasma and semen extenders on motility of frozen-thawed ram spermatozoa.
Ram seminal plasma increases the fertility of frozen-thawed ram spermatozoa deposited into the cervix. The aim of the current study was to compare the effect of ram seminal plasma to that of bull seminal plasma, dog prostatic fluid, protein-free TALP TrilEq (Triladyl with 0.5 mt of Equex STM paste added to each 100 mt) and heat-treated skim milk on longevity and percentages of progressively mot...
متن کاملChloride channels are involved in sperm motility and are downregulated in spermatozoa from patients with asthenozoospermia
Human spermatozoa encounter an osmotic decrease from 330 to 290 mOsm l-1 when passing through the female reproductive tract. We aimed to evaluate the role of chloride channels in volume regulation and sperm motility from patients with asthenozoospermia. Spermatozoa were purified using Percoll density gradients. Sperm volume was measured as the forward scatter signal using flow cytometry. Sperm ...
متن کاملRe: Sperm Motility Inversely Correlates with Seminal Leptin Levels in Idiopathic Asthenozoospermia.
BACKGROUND Asthenozoospermia is one kind cause of male infertility. Nevertheless, no specific etiology can be identified by routine tests in some cases. Recently, it has been shown that leptin plays a critical role in male fertility. However, the link between leptin and sperm motility is yet to be determined. The aim of this study was to explore association between seminal and serum leptin leve...
