#menarche

[butch-reidentified]

Hi, just wanted to put this out to you and Radblr in general - how would you suggest approaching the subject of first periods? My daughter is probably due to start in the next 12-18 moths, going on how old I was, and I don't want her to be scared or feel like there's anything wrong with her. I don't agree with that whole 'It makes you a woman' thing - she's way off being a woman, and a period or bra won't change that, but I really don't want her to hate her changing body either? I appreciate many people here probably don't have children, but any advice is welcome. Thank you.

So sorry this one took me ages to get to! I'm just now getting to all the asks that I received during the super hectic time right before my wedding since I wasn't online much.

I'm gonna open this up to feedback from my followers, bc honestly I'm not a parent (yet) and my mother didn't have a uterus (I'm adopted) so I never got that talk either!

If I think of something to add for you, I'll reblog this and add my usual anon ask tags (same ones used on this post)

Menarche o Unang Regla [VIDEO]

Having children earlier in life is genetically linked to dying younger (msn.com)

People who are genetically predisposed to having children earlier in life are less likely to live to the age of 76, according to an analysis of more than 270,000 people’s genomes.

A new way to estimate our maximum lifespan could help us extend it

Why we age is one of the biggest evolutionary mysteries. The process of natural selection might suggest that people should pass on genes that are advantageous to living longer, thus having more time to reproduce, but there has been no evidence to support this.

One of the leading explanations for why is that the genetic mutations that favour reproducing earlier in life could also result in a lower lifespan – an idea called antagonistic pleiotropy.

“It’s because natural selection largely cares about reproduction,” says Jianzhi Zhang at the University of Michigan. “So those mutations that are beneficial for reproduction, but may be detrimental afterwards, would still be selected.”

After conducting the largest study on the genetic link between reproduction and lifespan to date, Zhang and Erping Long at the Chinese Academy of Medical Sciences in Beijing have now found more convincing evidence for antagonistic pleiotropy.

The pair analysed genomes from 276,406 people in the UK Biobank, a long-term health study. All the chosen participants in this study were born between 1940 and 1969 and were of European ancestry.

For each person, the researchers calculated a polygenic score, an assessment of a mix of genetic variants linked to better reproductive health in early life. The higher someone’s score, the more likely they are to be fertile for longer.

They also collected information on the participants' lifespans – either how long they lived themselves, or how long their parents lived for those who were still alive.

By comparing the polygenic scores to the lifespan data, the pair found that people who had higher polygenic scores for reproductive health had a lower probability of living to 76 years old. There was no specific reason for using this age as a cut-off, says Zhang.

Most mammals go through the menopause - if they live long enough

Those born earlier also tended to have a lower polygenic score than those born closer to 1969, suggesting that traits that enhance reproduction are still being selected despite their impact on longevity, says Zhang.

“Our findings are in strong support of the antagonistic pleiotropy hypothesis,” he says. One potential mechanism is that some gene variants that enhance reproductive attributes may result in disease later in life. One such variant called rs12203592, for example, has been linked to some cancers.

The team now hopes to collect further data from more diverse populations to see if this trend holds. “Whether our results apply to African or Asian people, we don't know yet, but I think we can expect to see this pattern.”

It is also important to note that external factors, including medical advances, have been leading to people living longer and having fewer children on average. “These changes have been extremely impactful, such that genetic changes are minute compared to environmental factors,” says Zhang.

“[It is the] first strong evidence of antagonistic pleiotropy in humans, supporting a major pillar of evolutionary ageing theory,” says Steven Austad at the University of Alabama at Birmingham. “There had previously been abundant evidence in laboratory animals, but to extend to humans is important for recognising the generality of antagonistic pleiotropy.”

What do you remember about your menarche? What do you know about menstruation and menarche generally (without necessarily experiencing menstruation yourself)? How do you feel about menstruation and menarche?

With this video, I want to gather as many experiences, thoughts and feelings about menstruation and menarche as possible. This video is part of a research project of the Swiss Science and Youth foundation.

Climate Change and Periods

In today’s world, we do face climate change at a very rapid pace. And you know what, it actually affects periods. The time of 'menarche,' or the first menstruation, may shift as a result of climate change, increasing illness risk for women. Natural catastrophes and extreme weather events have an impact on environmental factors such as food availability and chemical release, which can lead to early or late menarche in menstruators.

Menarche can affect illness risk and health later in life because the menstrual cycle affects many essential activities in the body. Seasonal changes have an impact on your dietary pattern. In the summer, we eat mangoes, which raise our body temperature. The uterus contracts as a result of the increased heat in the pelvic region. A change in climate may also result in an increase in appetite. If you eat more in a colder climate, your body may produce more oestrogen, which changes the length of your period cycle.

Climate change also affects the way we exercise and how active we are. During the summer, one works out more regularly. The period cycle is pushed by a day or two.  When the weather becomes cold, though, you tend to reduce your physical activity, causing your periods to arrive a few days sooner.

We could see that climate change is real and has real consequences for our lives. Isn’t it high time that we act responsibly and tackle it? Let’s not disturb the natural cycle which in turn wouldn’t disturb the menstrual cycle of the menstruators.

Apparently I'm in a polling sort of mood today.

(Sorry there's no option for "see results," I'll update the notes with the percentages every so often.)

is it normal for your boobs to not be growing a lot or for me not to have my period…? i’m 13, and everyone else is ahead of me. :(

Hi Anon,

Here's the normal flow of puberty:

breast development (thelarche) -> the first step is the development of "breast buds," little pads of glandular tissue just behind the nipple

adrenal glands start working to make androgens, so you start getting pubic and armpit hair, developing BO, maybe acne

growth spurt

menses starts (menarche)

There's a pretty wide range of what's considered "normal" with the onset of puberty. Some girls/AFAB kids will notice the onset of breast development (thelarche) as early as 8, and others may not begin until some point after age 12. The "average" can vary based on geographic location, race and ethnicity, and nutritional status. In the USA, about 95% of AFAB kids have undergone thelarche by age 12.

Your ask says "not growing a lot," so I'm assuming you've had some breast development. Some breast development but no period by age 13 is totally normal. Once it's started, some people develop breasts quickly, some slowly, some get large breasts, some always remain small. Your period should follow within around 2 years of whenever your breast development started.

This is why your pediatrician asks to look at your chest and private parts, as embarrassing as that may seem. If you haven't had any nipple changes at all by age 13, your pediatrician refer you to an endocrinologist or will get some bloodwork done to make sure there isn't anything going on with your hormone levels. There are a lot of different reasons why the hormones may not be coming online properly.

So, no worries, Anon! Nothing good comes of comparing ourselves to others. For every kid out there despairing they didn't get their period by age 13, there's a 9-year-old being teased for developing breasts in the 4th grade.

FWIW - I didn't get my period until I was 14, and my boobs were pretty small until I was around 18.

✨  — twinkle, twinkle, little star!

a headcanon from my muses’ childhood or and a nursery-rhyme they remember from that time.

Until the age of seven, Tsuna spent every waking moment with her mother, for her father was often on long sea voyages from Othard to Thavnair. When Orihime would catch wind of his ship's arrival, it would always mean a feast for the three of them to celebrate. Her mother's sekihan was a treat she always looked forward to-- and for more than just the taste. Her father was meant to reach shore once more on the week of Tsuna's coming-of-age (obitoki-no-gi), but with the invasion of the Garleans becoming an imminent threat, his voyage was delayed. Tsuna and her mother ate sekihan that day alone, unknowing that it would be the last. While not a nursery-rhyme per se, her favorite bedtime story of her mother's was the one of the Ruby Prince: a tale in which a Hyuran fisherman and an Auri princess were brought together by a Kojin and wed in a palace under the sea. Every time her mother told it, the tale would be embellished-- much to Tsuna's delight-- but what Tsuna found the most fascinating was that the son they bore was said to have had almost no scales at all.

Miracle of a body

It runs through my body. It is my power. It is my infirmity. It comes regularly. It deceives and doesn’t come out. Ending days. Bad blood. Last layer. I am finally clean.

Menarche

Do you ever wonder if Knives was afraid, the first time he sprouted blades instead of feathers? Would have he been less terrified, if he wasn't alone?

Do you ever wonder if he begged for his brother to come and help him understand?

Do you think it hurt?
