【翻译组】冬季及初春的精子最健康

 

研究发现在这几个月强健的精子更多,这可以解释为何在秋天有较高的出生率。


根据一项新的研究,精子可不会有冬季抑郁的困扰。《纽约每日新闻》报道说,研究人员称,人类的精子一般在冬季和初春时,正是最健康的时候,“游泳”速度最快,这就使得在这几个月更容易受孕。


根据《纽约每日新闻》的报道,以色列研究人员发现,精子的浓度和快速蠕动的比例 - 自发和独立地移动的能力 - 从春天到夏天和秋天时会下降,在冬季和初春时反弹。

根据发表在《美国戏妇产科杂志》的研究报告,精子细胞的物理结构,也是在冬季和早春的几个月里最健康。研究人员在这个超过三年的研究项目中,共计测试了6,455份精液样本。


在这几个月的里,强健的精子更多,可以解释秋季较高的出生率,因为这意味着在前一年的冬天和初春,有更高的受孕率,《纽约每日新闻》报道说。


根据这份研究报告:“举个例子来说,在冬季那些男人每毫升精液中大约有70万的精子......在春天的时候,这些男人的精液中这一比率约为每毫升68万”。报告还指出,世界卫生组织的定义,任何超过每毫升15亿个精子的精液,都属于精子数量正常的精液。研究人员指出,有必要进行更多的研究,找以到确切的一年的时间与精子的健康之间的联系,但是有一些专家则认为,激素的变化和暴露于日光也是可能的因素。


近一半的生育的烦恼都源自精子的问题。在我们的“小小游泳家”(比喻精子)页面,看看一个男性可以做什么——以及,他应该避免做什么——以最大限度提高他制造大量耐寒,健康,快速游动的精子的可能。

Sperm Healthiest in Winter, Early Spring

Study finds robust sperm counts in these months explain higher birth rate in the fall.


Sperm are not suffering from the winter blues, according a new study. Researchers say that human sperm are generally at their healthiest and "swim" faster in winter and early spring, making it easier to conceive during those months, the New York Daily News reports.


Israeli researchers found that sperm concentration and the percentage of fast motility — the ability to move spontaneously and independently — decreased significantly from spring into summer and fall, rebounding in the winter and early spring, according to the New York Daily News report.

The physical structure of the sperm cells was also the healthiest in the winter and early spring months, according to the study published in theAmerican Journal of Obstetrics & Gynecology. Researchers tested 6,455 semen samples over the course of three years.

The robust sperm counts in these months would explain the higher birth rate in the fall, which means higher conception rates the previous winter and early spring, the New York Daily News reports.

"For example, those men produced 70 million sperm per milliliter of semen during the winter. …That compared to the approximately 68 million per milliliter the men produced in the spring," according to the report. The article also notes that the World Health Organization defines anything over 15 million sperm per milliliter of semen as a normal sperm count. Researchers noted that more studies are necessary to find the exact link between the time of the year and sperm health, but some experts suggest hormone variations and exposure to daylight as possible factors.

Nearly half of all fertility troubles are linked to sperm problems. Check out our Little Swimmers page for what a guy can do—and what he should avoid doing—to maximize his chances of making plenty of hardy, healthy, fast-swimming sperm.
