The secret power of menstrual blood | Jiabao Li | TEDxUTAustin

Key Concepts

• Menstrual Blood as a Stem Cell Source: Menstrual blood contains pluripotent stem cells with significant potential for regenerative medicine.
• Clitoral Regeneration: The possibility of growing a functional clitoris in vitro using menstrual stem cells and 3D bioprinting.
• Female Anatomy & Scientific Neglect: Historical and ongoing underrepresentation and misunderstanding of female anatomy in scientific research.
• Matriarchal Societies & Anatomy: The connection between female anatomy (specifically clitoral structure in hyenas and elephants) and social dominance.
• Bio-capitalism & Reclamation: Utilizing platforms like OnlyFans to reclaim narratives around sex, pleasure, and science, and challenge traditional bio-capitalistic models.
• Organ Transplantation & Menstrual Blood: Potential for using menstrual blood-derived stem cells to grow organs for transplantation, reducing waitlists and immune rejection.
• Gender Imbalance in Science & Society: The historical and ongoing systemic biases against women in science and broader societal structures.

The Under-Explored Power of Female Biology

The speaker begins by recounting her first exposure to detailed anatomical representation – a penis museum in Iceland – at age 19, which prompted a realization of the lack of equivalent representation for female anatomy. This personal anecdote sets the stage for a discussion of the historical and ongoing neglect of female biology in scientific research and public understanding.

Female Anatomy: Beyond the Expected

The presentation challenges conventional understanding of animal anatomy, starting with the surprising discovery of the hyena and elephant clitoris. These animals possess remarkably large, internally retracting clitorises, and their anatomy is linked to matriarchal social structures. The speaker emphasizes that, unlike human societies, in these species, female anatomy physically prevents forced sexual activity, highlighting a stark contrast in power dynamics. Recent research (2022) revealed that snakes also possess clitorises, previously misidentified as scent glands, further demonstrating the historical oversight in studying female reproductive anatomy. The speaker argues this oversight stems from centuries of male dominance in science, citing historical examples like medieval witch-hunting guides that demonized the clitoris as "the devil's teeth."

Growing a Clitoris in a Dish: A Scientific Breakthrough

Driven by this historical neglect, the speaker and her team embarked on a project to grow a living clitoris in vitro. The process leverages the unique properties of stem cells found in menstrual blood. These cells are pluripotent, meaning they can differentiate into a wide range of cell types – more versatile than many other stem cell sources. The methodology involves:

1. Collection of Menstrual Blood: Obtaining menstrual blood as a source of stem cells.
2. Stem Cell Harvesting: Isolating the stem cells from the menstrual blood.
3. Differentiation: Guiding the stem cells to differentiate into erectile cells and neurons.
4. 3D Bioprinting: Utilizing 3D bioprinting to create a clitoris structure and implant the differentiated cells.

The resulting structure is not merely a physical replica but a functional organ capable of sensing and potentially experiencing arousal and pleasure. The speaker playfully raises the philosophical question of sentience, drawing a parallel to experiments demonstrating human brain cells in a dish playing Pong, and suggesting the possibility of a “thinking” clitoris capable of engaging in activities like swiping on Tinder. This research is being shared and funded through an OnlyFans account ("sentinit"), intentionally subverting the platform’s objectifying nature to reclaim narratives of sex, pleasure, and science.

Menstrual Blood: A Hidden Reservoir of Health Information

Beyond clitoral regeneration, the speaker highlights the untapped potential of menstrual blood as a source of valuable health information. Analysis using mass spectrometry revealed unique proteins present only in menstrual blood, linked to conditions like fertility issues, endometriosis, and cervical cancer. This offers the possibility of developing non-invasive monthly health tracking methods, eliminating the need for needles and providing early detection of potential health problems. The speaker visually represented this research through an artistic installation, "Menstrual Garden," featuring scents and enlarged protein structures.

Addressing Organ Transplant Shortages & Personal Motivation

The potential of menstrual blood-derived stem cells extends to organ regeneration. Currently, stem cell harvesting is invasive, requiring procedures like bone marrow aspiration. Menstrual blood offers a non-invasive alternative. Research has shown these stem cells can be differentiated into neuro cells to treat Alzheimer’s disease and heart cells to repair damaged heart tissue – “use blood to patch a broken heart.” With over 20,000 people on organ transplant waiting lists globally, the speaker envisions a future where organs can be grown from a patient’s own menstrual blood, eliminating the risk of immune rejection. This research is deeply personal; the speaker is attempting to grow a heart from her own menstrual blood for her mother, who suffered a heart attack and whose symptoms were initially misdiagnosed due to a lack of awareness of female-specific heart attack presentations.

A Legacy of Overcoming Gender Bias

The speaker connects her scientific pursuits to her own family history, revealing that she wouldn’t exist if her mother hadn’t fought against societal pressures and the one-child policy in China, which often led to the abortion of female fetuses. Her mother’s unwavering belief in her potential fueled her education and ultimately her career. The speaker aims to transform menstruation from a taboo subject into a “superpower” with the potential to improve sexual health, address genital mutilation, aid transgender and intersex individuals, and revolutionize healthcare. However, she acknowledges the potential for backlash, questioning whether society will embrace female empowerment or attempt to control and exploit it.

Call to Action & Future Outlook

The speaker concludes with a call to action, urging investment in research that benefits women, emphasizing that such research ultimately benefits everyone. She ends with a personal note, requesting menstrual blood donations for her ongoing research, and expressing her hope that her daughter will grow up in a world where female anatomy is openly studied and celebrated, symbolized by the existence of a clitoris museum.

Technical Terms & Concepts

• Pluripotent Stem Cells: Stem cells capable of differentiating into any cell type in the body.
• Mass Spectrometry: An analytical technique used to identify and quantify molecules based on their mass-to-charge ratio.
• 3D Bioprinting: A manufacturing process that uses bio-inks (containing cells and biomaterials) to create three-dimensional structures.
• Erectile Tissue: Tissue capable of becoming engorged with blood, leading to an erection.
• Neurons: Nerve cells responsible for transmitting information throughout the body.
• Genital Mutilation: Procedures involving partial or total removal of the external female genitalia, often performed without medical justification.
• Intersex: A general term used for a variety of conditions in which a person is born with reproductive or sexual anatomy that doesn't fit typical definitions of male or female.
• Endometriosis: A condition where tissue similar to the lining of the uterus grows outside of it.
• Bio-capitalism: A system where biological processes and materials are commodified and exploited for profit.
