上級の 熟考する／考慮する author, Dr Gabor Huszar, said: 'Our results could help 演説（する）／住所 the fact that だいたい 40 per cent of infertility 事例／患者s can be traced to male infertility.'

Dr Huszar said that past semen 分析 焦点（を合わせる）d on sperm 集中 and mobility. It was assumed that a man was fertile if he had a high sperm count and active sperm.

However, there was no （警察などへの）密告，告訴（状） on the sperm’s fertility or its ability to attach to its 示す - the 女性（の） reproductive 独房.

In an ideal 事例／患者, the egg 自然に selects the optimal sperm and 封鎖するs off the others. But during in-vitro fertilization 治療 of men who had only a few sperm, clinicians do not know if they are 注入するing the 'winning' sperm into the egg for fertilization.

'We have now 設立する a biochemical marker of sperm fertility so that we can select sperm with high genetic 正直さ,' Dr Huszar said.

The 研究員s 実験（する）d the idea that high 質 sperm would 貯蔵所d itself to hyaluronic 酸性の using semen 見本s from 50 men. Part of the 見本 was 許すd to 貯蔵所d with the hyluronic 酸性の marker. These were then compared with the sperm that did not 貯蔵所d.

They 設立する the higher-質 sperm was more likely to 貯蔵所d to the 酸性の.

Dr Huszar に例えるd those that did not 貯蔵所d to scratched CDs.

'They seem to be 操作の but when you play them, some of the （警察などへの）密告，告訴（状） is 行方不明の,' he said.

'These 損失d sperm may also carry chromosomal aberrations that could be 関係のある to genetic 病気s.'

Their results are to be published in the 熟考する／考慮する published in the June/July 問題／発行する of the 定期刊行物 of Andrology.
