Modifications of some parameters of the rabbit ejaculate after ablation of the vesicular gland

An evaluation is made of the influence which the vesiculectomy may have on the ejaculate in the rabbit. To do this we have studied three different factors in the semen, before and after the operation: quality control parameters (volume, vitality and concentration), presence or not of the mucous plug and levels of different ions (sodium, potassium, calcium and magnesium) in the rabbit's seminal plasma. At the same time we performed periodical determinations of these ions in the blood plasma, in order to rule out the fact that the variations of the cation levels in the seminal plasma could be due to alterations of these levels in the bloodreduction in the seminal quality parameters analysed (46,4% for concentration, 29.5% for vitality and 45,6% for volume). On the other hand, as far as the concentration of the different ions in seminal plasma is concemed, a significant fall in the case of sodium (21.1 %) is observed and a parallel increase of the calcium, magnesium and potassium ions, although the difference is only significant in the first of the three (19%) ..
