Context: in China there is a female biologist by the name Professor Hongmei Wang, who is a biologist at the State Key Laboratory of Stem Cell and Reproductive Biology in Beijing, is conducting research aimed at extending the female reproductive lifespan and delaying menopause. Her work is largely motivated by the biological reality that women are born with a finite egg reserve that depletes with each cycle.
Professor Wang is exploring the theoretical possibility of reducing the frequency of menstruation to once every three months (four times a year). She proposes that by reducing the frequency of menstruation from monthly to quarterly (four times a year), the rate of follicle depletion could be slowed. The theoretical goal is to preserve a woman’s finite egg supply, potentially extending the fertile window into the late 40s and delaying the onset of menopause.
Beyond cycle modulation, Wang has achieved groundbreaking results in regenerative medicine. Her team pioneered techniques using stem cell transplants to treat premature ovarian failure. After successfully restoring fertility in rhesus monkeys, Wang moved to human clinical trials. These trials demonstrated that injecting stem cells into the ovaries could "reactivate" reproductive function in women previously deemed infertile, leading to the birth of healthy children.
Wang’s research is part of a broader effort to address China's declining birth rates and aging population. While much of her work on altering menstrual cycles is currently limited to mouse experiments and theoretical models, it has gained significant global attention for its potential to give women more biological options and flexibility in family planning.
The main purpose of this is part of a broader effort to address China's declining birth rates and aging population. While much of her work on altering menstrual cycles is currently limited to mouse experiments and theoretical models, it has gained significant global attention for its potential to give women more biological options and flexibility in family planning and of course combat the declining global birth rate especially in countries with low birth rate and aging population.
If this becomes a success and we manage to extend fertility and reduce menstruation to four times a year, how will this affect the world of Halacha in general and specifically the Laws of Niddah and family purity?
