'I have the feeling that in spite of all the pain, unpleasantness and nastiness I have a sweet secret.' (Anne Frank, writing about menstruation in her diary)
Hi. Menstruation is very interesting from an evolutionary perspective. I will be collecting latest research and reports, for now here are some ideas to explore:
Age of first period in tribal society compared to present day.
How many periods women had in tribal society compared to present day (i.e. in our evolutionary past women would menstruate, get pregnant, breastfeed. Therefore have many less periods.)
Studies show a relationship between high number of periods and breast cancer.
Studies show that girls begin to menstruate earlier if their father is not around.
The visibility of menstruation as opposed to hidden ovulation (sign of fertility).
Why do women menstruate if it is such an unnecessary waste of nutrients?
Menstruation ceases if environment is harsh.
Synchronicity of female cycle with other females.
Menstrual cycles of lesbians compared with heterosexual women.
Role of orgasm and seminal fluid.
Cheers,
Karene
This study observed an increased breast cancer risk in women with a higher number of cumulative menstrual cycles in their lifetime.

Several reproductive factors have been linked to increased risk of breast
cancer - from early menses and late menopause to childlessness and late
age at first pregnancy. A new study would add yet another: menstrual cycles
that are typically either shorter or longer than average.
The researchers suspect that hormones in general, and their peaks during
an ovulatory cycle, collectively affect cancer risk.

The purpose of this study is to examine the relationship between diet, physical activity and when a woman has her first menstrual period (menarche). The exact cause (or causes) of breast cancer remains unknown; however, certain aspects of a woman's life appear to increase her chances that she will develop breast cancer during her lifetime. A woman who has her first menstrual period at an early age is more likely to be diagnosed with breast cancer than a woman who has her first menstrual period at a later age.

which provides an excellent opportunity to present to the world the latest
knowledge about the thing we all find most interesting - sex! The work will
not just benefit humanity, it will profoundly enhance your own sexuality
as you learn more about our complex and diverse sexual evolution.
We seek help in finding the latest scientific (evolutionary)
research on our biological and cultural sexual evolution and distributing
content (overviews / summaries) to relevant pages.
This site is well respected. We are listed as the
Top
Philosophy Website on the Internet with around 300,000 page views each
week. So your contributions will be seen and read, and will be providing
humanity with a great source of wisdom about a very important subject (that
currently suffers due to cultural / religious myths).

Many thanks! Karene
Analyse
any human emotion, no matter how far it may be removed from the sphere of
sex, and you are sure to discover somewhere the primal impulse, to which
life owes its perpetuation. ... The primitive stages can always be re-established;
the primitive mind is, in the fullest meaning of the word, imperishable.
... Mans most disagreeable habits and idiosyncrasies, his deceit, his cowardice,
his lack of reverence, are engendered by his incomplete adjustment to a
complicated civilisation. It is the result of the conflict between our instincts
and our culture. (Sigmund Freud)
