In former studies we could show, that the menarche of Görlitz-born girls accelerated from annual-set to annual-set between 1944 and 1953. The annual-sets 1954 to 1958 have constantly a mean-age of menarche from 12 years and 3 months. In 1959 and 1960 born girls we find now, that they have a menarche-mean-age of 12 years and 10 months. Also there are some girls, which had her menarche first again after ending her 15. year of life.
在之前的研究中我们可以表明，出生于格尔利茨的女孩的初潮在1944年至1953年间从每年设定的时间加速到每年设定的时间。1954年至1958年的每年设定时间，初潮的平均年龄一直是12岁零3个月。现在我们发现，1959年和1960年出生的女孩，她们初潮的平均年龄是12岁零10个月。此外，还有一些女孩在15岁结束后再次迎来初潮。
