title: Effect of different timings of the day on semen and calcium and magnesium in it.
abstract: OBJECTIVE
  The study was conducted to understand the effect of time of the day on semen parameters as well as on the level of two electrolytes, calcium and magnesium, in it.
  
  
  METHODS
  A total number of 27 normal healthy adults submitted 156 ejaculates during six different fixed timings of the day on six different occasions.
  
  
  RESULTS
  A significant observation was that semen quality was superior in terms of total sperm count percentage and active motility at 0000 hours. A second peak was seen at 0800 hours. Calcium and magnesium level in seminal plasma was maximum at 0000 hours. No significant difference was observed in case of spermatozoa elements among different timings.
  
  
  CONCLUSIONS
  The study showed that probably the release as well as the quality of sample was dependent on blood androgen.
