The seasonal fluctuations of infection and sperm activity in the temperate climate

الملخص EN

Widal and Rose Bengal tests were conducted for patients who were attending to the High Institute of Infertility Diagnosis and Assisted Reproductive Technology / Al-Nahrain University and a private Laboratory during the years 2005-2007.

Monthly variation in the incidence of infections and the number of motile sperms were studied.

For Widal test a titer of 1 : 80 regarded as negative, and a titer of 1 : 160 and more considered positive for O and H antigens with visible agglutination.

Brucello-slide test was used to detect brucella–specific agglutinins.

The positive sera for each of Brucella and Salmonella were 140 and1505, during the years 2006, 2007and 2005, 2006, 2007 respectively.

The seminal fluid analyses were evaluated separately for other 4398 patients during the years 2006-2007 to detect the number of motile sperms.

The study revealed a significant difference between winter and summer, higher in summer than winter with respect to Brucellosis [p < 0.05], Salmonillosis [p < 0.0001].

In contrast, the number of motile sperms was higher in winter than summer [p < 0.01].

On the other hand, the study may refer to the presence of a similar regular rhythm of the infections that take place and the vitality of spermatozoa during different months of the year.
