%X The aim of this study was to retrospectively
evaluate the effects of male age and ejaculatory abstinence on semen parameters
and reproductive hormones among men residing in Africa and the Middle East.</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">A total of 70,142 semen analysis results were
analysed and grouped according to the age intervals (16</span><span style=\"font-family:&quot;\"> - </span><span style=\"font-family:&quot;\">20, 21</span><span style=\"font-family:&quot;\"> - </span><span style=\"font-family:&quot;\">30, 31</span><span style=\"font-family:&quot;\"> - </span><span style=\"font-family:&quot;\">40, 41</span><span style=\"font-family:&quot;\"> - </span><span style=\"font-family:&quot;\">50, 51</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">-</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">60, &gt;60) and ejaculatory abstinence (&lt;2 days,
2</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">-</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">5 days and &gt;5 days).</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">Semen parameters <i>i.e</i>.</span><a name=\"_Hlk91588276\"></a><span style=\"font-family:&quot;\"> </span><span><span style=\"font-family:&quot;\">volume, concentration,
progressive motility, <a name=\"_Hlk91589920\"></a>total progressively motile count,</span></span><span><span style=\"font-family:&quot;\"> </span></span><span><span style=\"font-family:&quot;\">morphology,</span></span><span></span><a name=\"_Hlk91589960\"></a><span><span style=\"font-family:&quot;\"> </span></span><span><span style=\"font-family:&quot;\">total normal sperm count</span></span><span style=\"font-family:&quot;\">, DNA fragmentation, viability, sORP, normed sORP
were specifically evaluated. Additionally, for each age interval,</span><span style=\"font-family:&quot;\"> </span><span style=\"font-family:&quot;\">reproductive hormones <i>i.e</i>. estradiol, luteinizing hormone, follicle stimulating hormone,
testosterone and prolactin were evaluated.</span><a name=\"_Hlk115952578\"></a><span style=\"font-family:&quot;\"> </span><span><span style=\"font-family:&quot;\">Semen volume, total
progressively motile count, sperm morphology and total normal sperm count
constantly decrease significantly</span></span><span><span style=\"font-family:&quot;\"> </span></span><span><span style=\"font-family:&quot;\">after the age of 30 years.
