是溫差大ㄉ原因嗎?
最近鏡檢時發現公豬精蟲都是一團一團ㄉ 只有3 4成活動力不錯 也沒啥大問題這樣ㄉ精蟲能配ㄉ上嗎?????? 有換 稀釋液?偶的經驗是 葡萄糖會有此種情況蒸餾水比較不會 懷疑是分子結構不同
有"專家"?教一下 !

There is very data to suggest that sperm clumping has a significant effect on fertility. However, these cells are often non-motile spermatozoa that may have been either damage during transit through the testicle or traumatized following ejaculation. Other possible causes for semen clumping can include wide temperature fluctuations during transport (± 5º C), and bacterial contamination.
It appears is important to consider the degree of clumping when calculating sperm concentration even though there is very little evidence to suggest that clumping in semen affects fertility. However, clumped sperm often dissociate when diluted for spectrophotometer or hemacytometer counting and viable sperm numbers for semen doses may be grossly underestimated if the prevalence of sperm clumping is not initially accounted for. Occasionally you may see spermatozoa movement within these clumps of cell, however, there is not enough evidence that these cells dissociate after insemination. Therefore, regardless of the apparent motility in clumps, adjustments to whole sperm counts should be based on the occurrence of clumping in these ejaculates. Clumping may be associated with individual boars, boar and semen extender interactions, and management. The prevalence and impact that sperm cell clustering has on semen viability and fertility needs further investigation.
What is Sperm Agglutination?
Sperm agglutination refers to sperm “clumping” due to infection or the presence of sperm antibodies. Clumping inhibits sperm’s mobility and ability to fertilize a female’s eggs.
Causes of Sperm Agglutination
Sperm agglutination occurs when the body’s immune system recognizes its own sperm as foreign and deploys sperm antibodies to fight it. The antibodies attach themselves to the sperm forcing them to clump together. When the sperm are coated by the antibodies, their mobility becomes reduced and their receptors, which allow the sperm and egg to recognize each other, are........... 本文章最後由 tomcatto 於 2012-10-19 19:16 編輯

全文在此 重點是
1. 計數時，凝集的都不算，只計單一的
2. 如果是經冷藏過的精液則需要注意冰箱的穩定性及須隔水冷藏 :@:@:@ 小蘇好人做到底 直接用中文解釋一下 顧問費直接找6564就好;P 顧問費直接找豬小弟弟 顧問費直接找豬小弟弟 是新鮮精液鏡檢時就有這樣ㄉ狀況ㄟ 之前並沒有這樣ㄉ狀況 關乎營養嗎?????目前是吃母前料
