Semen analysis before and after antibiotic treatment of asymptomatic chlamydia- and ureaplasma-related pyospermia.
Pyospermia is the abnormally high concentration of white blood cells in human ejaculate, as caused by a bacterial infection. This study addresses the evaluation of the use of an antibiotic treatment in infertile patients who show asymptomatic pyospermia through the monitoring of semen analysis param...
Progesterone activates Janus Kinase 1/2 and activators of transcription 1 (JAK1-2/STAT1) pathway in human spermatozoa.
We investigated the existence, the Janus kinase (JAK) and activator of transcription (STAT) pathway and determined its physiological relevance. JAK1 and STAT1 are localised on the equatorial region and the midpiece of their human spermatozoa, JAK2 is detected on the sperm tail. Capacitation leads to...
Quality of 4-hourly ejaculates - levels of calcium and magnesium.
A four-hourly ejaculation study was conducted in which eleven normal healthy subjects participated. Five of them discontinued after submitting three samples. One alone was present for submission at the end of 16 h (fifth ejaculate), which was his last submission. Physical exhaustion was the sole rea...
Serum testosterone levels in diabetic men with and without erectile dysfunction.
We sought to evaluate the effect of associated co-morbidities on serum total testosterone (TT) level in men with type 2 diabetes DM, either with or without erectile dysfunction (ED). Three hundred and ninety-one patients were evaluated for erectile function using an abridged, five-item version of th...
Comparison of the efficacy of three concentrations of retinoic acid for transdifferentiation induction in sheep marrow-derived mesenchymal s...
Recent studies have shown the unique role of retinoic acid (RA) in the induction of transdifferentiation in mesenchymal stem cells (MSCs) into germ cells (GCs). This study is the first study that compares the efficacy of three different concentrations of RA for the production of male...
Re: Prevalence of ejaculatory disorders in urban men-results of a random-sample survey.
Proteomic analysis of seminal plasma in men with different spermatogenic impairment.
We compared the protein expression profiles of seminal plasma from four different groups of men as follows: normozoospermic, asthenozoospermic, oligozoospermic and azoospermic groups, using two-dimensional differential gel electrophoresis (2-D DIGE). We found eight proteins with statistically signif...
Low sex ratio in children of professional basketball players in Spain.
The aim of this study was to ascertain the variations in the reproductive sex ratio (number of men to number of women) among male professional basketball players in Spain. This retrospective, cross-sectional study is based on a survey conducted in the Spanish professional basketball leagues during th...
Effect of aracnotoxin from Latrodectus mactans on bovine sperm function: modulatory action of bovine oviduct cells and their secretions.
Latrodectus mactans' aracnotoxin (Atx) induces changes in sperm function that could be used as a co-adjuvant in male contraceptive barrier methods. This effect includes the suppression of intracellular reactive oxygen species (ROS), an event necessary for capacitation, chemotaxis and...
Cryopreservation of human sperm: efficacy and use of a new nitrogen-free controlled rate freezer versus liquid nitrogen vapour freezing.
Preservation of spermatozoa is an important aspect of assisted reproductive medicine. The aim of this study was to investigate the efficacy and use of a recently developed liquid nitrogen and cryogen-free controlled rate freezer and this compared with the classical liquid nitrogen vapour freezing met...
