This study aimed to report a rare case of intermittent azoospermia and ring-like small supernumerary marker chromosomes (sSMCs). An infertile man was diagnosed with azoospermia presenting a normal male phenotype with complete masculinization. Karyotyping and polymerase chain reaction (PCR) were used
Fructose is secreted from the seminal vesicles and the accessory sex glands. It is the major carbohydrate source in seminal plasma and essential for normal sperm motility. The objective of this prospective descriptive study was to measure fructose concentrations in seminal plasma from men with
The ultrastructural characteristics of the testicular tissue in male infertility and the isoenzyme spectrum of some enzymes in sperm cells have been studied. The testicular material was taken by Vilar's method from three healthy males with normospermia and eleven males with hypogonadism, azoospermia
As part of the work, an assessment was made of the state of the metabolic characteristics of sperm plasma in various morphofunctional ejaculate pathologies. Physico-chemical, metabolic and morphological parameters of the ejaculate were evaluated. The diagnostic protocol included a standard sperm
Semen abnormality (SA) male infertility has become a worldwide reproductive health problem. The invasive tests (e.g., testicular biopsy) and labor-intensive methods of semen collection severely inhibit diagnosis of male infertility. In addition, the pathogenesis and biological interpretation of male
The aim of this study was to elucidate the effects of an Asian diet compared to a Western diet on sperm numbers and quality, and serum hormones in cynomolgus monkeys (Macaca fascicularis) injected with testosterone enanthate (TE) plus depot medroxyprogesterone acetate (DMPA). Thirty male monkeys
Gas chromatography--mass spectrometry with an on-line data system was used to identify monosaccharides and monosaccharide derivatives in human seminal plasma. The carbohydrates were converted into the methoxime-trimethylsilyl derivatives before separation in open tubular glass capillary columns
The neutral sugar content of proteins of human seminal plasma from different clinical diagnoses has been determined by gas-liquid-chromatography. Galactose, mannose, glucose and fucose were the predominant carbohydrates. Sometimes small quantities of arabinose, rhamnose, xylose and ribose were
The prevalence of obesity is increasing worldwide, with a corresponding increase in overweight and obese patients referred with infertility. This systematic review aimed to determine whether non-surgical weight reduction strategies result in an improvement in reproductive parameters affected by
