Sperm density – Sperm Concentration - some facts<br />
Ideal semen volume <strong>and</strong> sperm density are achieved after<br />
2-3 days abst<strong>in</strong>ence period<br />
Shorter abst<strong>in</strong>ence periods decrease sperm density<br />
Tyler et al., 1982; Nnatu et al. 1991<br />
Longer abst<strong>in</strong>ence periods <strong>in</strong>crease sperm density, but also<br />
<strong>in</strong>creases the proportion of dead, immotile or morphologically<br />
abnormal sperm<br />
Pellestor et al, 1994<br />
The highest concentration of sperm is <strong>in</strong> the <strong>in</strong>itial portion of the<br />
ejaculate<br />
Daily practice to solve unexpected azoospermia –<br />
Albeit the different knowledge <strong>in</strong> the literature<br />
1. Repeated Ejaculation.<br />
especially <strong>in</strong> the cryptozoospermia group, a<br />
repeated ejaculation may produce better quality of<br />
ejaculate.<br />
In our experience, p about 30% will have better qquality y<br />
<strong>in</strong> their repeated sperm sample than <strong>in</strong> the first one.<br />
2. Immediate TESE if no sperm is present , also not <strong>in</strong> the<br />
repeated ejaculate<br />
S<strong>in</strong>ce 2007 we had 8 patients with no visible sperm <strong>in</strong> their first<br />
<strong>and</strong> second ESP on which urgent TESE was performed.<br />
Sperm was found <strong>in</strong> 4 of them.<br />
In a study where 3 cases were taken to Urgent TESE only <strong>in</strong> one of<br />
them sperm were detected.<br />
Song SH et al., 2010<br />
Mean<strong>in</strong>g,<br />
Urgent TESE is not a treatment with which sperm presence is<br />
guarantied, also not <strong>in</strong> crypto azoospermia.<br />
