Preoperative and postoperative sperm parameter values from infertile men with varicocele were analyzed by computer-aided sperm analysis (CASA) to assess if sperm characteristics improved after varicocelectomy. Semen samples of men with proven fertility (n = 38) and men with varicocele-related infertility (n = 61) were also analyzed. Conventional semen analysis was performed according to WHO (20...

BACKGROUND ICSI into the oocyte is the only treatment currently available for most male patients with severe oligozoospermia who wish to father children. In order to perform ICSI, motile sperm need to be recovered from the ejaculate and, if no sperm or not enough motile sperm are recovered on the day of ICSI, testicular sperm extraction (TESE) must be performed. Oxytocin stimulates epididymal c...

The objective was to monitor sperm counts and bacterial presence on randomly pooled semen doses over 3y and to determine effects on the farrowing rate and total born in two large farm systems, each serviced by their own boar stud. Sperm counts were divided into increments of 0.5x10(9) for data analysis. There was no effect of sperm count or the presence of bacteria on farrowing rate (n=9502 obs...
