Quality of 4-hourly ejaculates - levels of calcium and magnesium
Summary 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...

| description | Summary
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 reason for all participants for their discontinuation from the study. The result showed a decrease in semen volume and sperm count from first to last ejaculate. The increase in motility was probably due to reduction in exposure time to sperm motility inhibitory factors. In general, total motile spermatozoa as well as actively motile spermatozoa progressively increased from first to last ejaculate at the cost of sluggish spermatozoa. A significant increase in seminal plasma calcium and magnesium was seen as well as a significant increase in magnesium inside the cell from the first to the fourth ejaculate. Considering the quality of semen, which was good in sperm count and excellent in motility, calcium and magnesium may be helpful in cleaning motility inhibitory factors of spermatozoa. |
