岁数：一个被忽视的不育因素

根据一项有助于呼吁开展国内避免子代文化教育项目的简报，数百万加拿大人将发掘出生个父母比他们现实生活的更是难了，甚至有些人根本就不能受孕了。 这个区域性受孕深入研究结果显示，岁数在30到39岁的人中有88%的年长者和57%的男士看来自己没有受孕缺陷。 但是，他们错了。 子代就在我们陪伴——每六对前妻中就有一对遭受子代困扰——因为今天人们要父母的岁数先于，这样留给受孕的时间大大减少。只有27%的男士在30岁以前生下第一个父母，而30年前这个二进制是92%。受孕岁数先于是子代的一个主要缺陷，想想看，一个男士在21岁时有超过1百万个卵细胞，但是到了27岁就只有约150000个了。 主管新南威尔士受孕基金会保护受孕力计划的Anne Clark宣称，岁数对男士受孕力的制约存在着联想，而岁数对年长者受孕力的制约则存在着更是多的联想。 在被追查的2400人中，只有2%的人看来年长者子代是接受液受精用药的状况，没法看来岁数是避免子代的因素。但受孕基金会宣称，年长者子代是设法液受精用药的夫妻中最常见的状况。 Clark 内科医生向联邦活动家们展示了受孕基金会的深入研究结果，这些活动家们专门组织了一个工作小组以推动一个东欧国家受孕财政政策。 该工作小组一位叫Liberal MP Mal Washer的协作者把对子代的忽略嘲弄为“一个东欧国家的灾难”，他宣称：“追查结果显示，一场关于受孕岁数、吸烟以及其他诸如肥胖等因素避免子代的国内文化教育战役困难重重了”。 现代医学胚胎学家Ian Fraser 去找活动家们抛开无需保护受孕率的财政政策不说，当局在这个缺陷来得很严重的时候最终对一些受孕深入研究得出结论正式反应。这包括Fraser博士2005年的一个简报，在该简报中，Fraser博士介绍了很多关于年长者子代用药和公众文化教育缺陷。 联邦当局卫生部法律顾问Tony Abbott 说，当局还在重新考虑Fraser的简报“这个简报以及当局的决策则会在年底公布”。受孕深入研究深入研究宣称：就算人们知道了岁数对于受孕的制约，也可能会对人们决定何时受孕父母造成制约。 Clark内科医生说：与一些风靡一时的看法比如说，选择晚生父母并不是男士集中精力她们的足球员，而是设法稳定的关系和经济保障。被追查的男士将足球员状况排到了14个制约她们得出结论受孕父母的决定因素的第13位，30岁时还没有父母的男士中有三分之一是因为她们没有同性恋者。 Clark宣称，今天的观念发生变化迫使人们受孕父母的岁数先于，任何文化教育活动都应当鼓励那些在30多岁企图受孕父母，但经过6到12个月初的为了让还不能成功的前妻设法借助。

Ignorance a factor in infertilityAnnabel StaffordOctober 13, 2006MILLIONS of Australians will find it much harder to have children than they expect — or may not be able to have them at all — according to a landmark new report that has led to calls for a national education program to prevent infertility.The National Fertility Study shows that 88 per cent of men and 57 per cent of women between the ages of 30 and 39 reckon they will have children without any problem.They're wrong.While infertility has always been around — one in six couples will suffer from it — because people are now having children much later in life, the time left to conceive has been cut dramatically. Just 27 per cent of women have their first child before they turn 30, compared to 92 per cent 30 years ago. This is a major problem for fertility considering that at 21 a woman has more than 1 million eggs while at 27 she has only about 150,000.Anne Clark, who runs the fertility preservation project for the Fertility Society of Australia, said while there was misunderstanding about the effects of age on a woman's fertility, there was even more misunderstanding about its effects on a man's.Only 2 per cent of the 2400 people surveyed believed a man's infertility was a reason people got IVF treatment and none believed a man's age was a factor. But male infertility is the most common reason couples seek IVF, according to the Fertility Society.Dr Clark presented the results of the Fertility Study this week to federal politicians who have formed a group dedicated to promoting the need for a national fertility policy.The group's co-ordinator, Liberal MP Mal Washer, described ignorance about fertility as "a national disaster". The survey proved the need for a national education campaign about the effects on fertility of age, smoking and other factors such as obesity, he said.Reproductive medicine expert Ian Fraser told the politicians that despite the desperate need for a fertility preservation policy, the Government had failed to release or publicly respond to several reviews into infertility made since it had come to power. These included a 2005 review by Professor Fraser, which is believed to recommend more public education about and treatments for male infertility.A spokeswoman for federal Health Minister Tony Abbott said that the Government was still considering the Fraser review and "the report, together with the Government's response, will be made public before the end of the year".The Fertility Study suggests that even if people know about the effect of age on fertility, it may not change decisions about when to have children.Contrary to popular belief, later childbearing was not due to women pursuing their careers, but to a desire for stable relationships and financial security, Dr Clark said. Surveyed women rated career equal 13th of 14 factors that would influence their decision to have children, while one in three women in their 30s had no children because they had no partner.Dr Clark said that because such societal changes were forcing people to have children later, any education campaign should also encourage couples in their 30s to seek help if they were unable to conceive after six to 12 months of trying.
