The posts reflect a high level of interest in the evolutionary origins of menstruation, with examples like the mention of diverse species that menstruate and the discussion of its adaptive functions. The tone varies from curiosity to scientific analysis, showing both engagement and recognition of the article’s significance in understanding reproductive biology.
AgreementModerate agreement
Most discussions recognize the validity and importance of the research, with some supporting the idea that menstruation evolved as a defense mechanism.
InterestHigh interest
The discussions consistently show curiosity about the evolutionary aspects of menstruation across different species, indicating high interest.
EngagementModerate engagement
Participants reference multiple sources, models, and processes, suggesting active engagement with the scientific concepts.
ImpactModerate impact
While the discussions highlight interest and engagement, they mostly focus on understanding rather than immediate practical implications, leading to a moderate impact score.
Abstract in brief
The paper explains that human menstruation likely evolved from a process called spontaneous decidualization (SD), which is a hormone-driven change in the uterine lining, as a result of maternal-fetal conflicts over pregnancy.
It proposes that SD originally evolved in nonmenstruating species as a fetal-induced reaction, but in humans, it became genetically fixed, allowing the body to prepare for pregnancy independently of fetal signals.
The authors present three models of how SD might have evolved through genetic assimilation, and suggest that understanding this process can help us better understand reproductive health issues like endometriosis and pregnancy loss.]

A menstruação é um fenômeno raro na natureza! Neste vídeo iremos conhecer quais espécies, além do humano que também menstruam e entender um pouco mais sobre a menstruação
Neste vídeo iremos explorar as origens evolutivas da menstruação e entender pq ela é o resultado não intencional de uma "guerra" entre o útero e o embrião!
Vem entender mais sobre a evolução em nós mamíferos
Interesting example of adaptationist thinking in human biology.
Hyp: menstruation is the byproduct of spontaneous decidualization of the endometrium, which evolved as a line of defense against invasive fetal tissues and/or for embryo selection. https://t.co/fOimY10fqh https://t.co/jGwYlhtyDl
Nos animais que menstruam a gestação é controlada pelo corpo da mãe. Enquanto nos animais de ciclo estral o embrião é que controla as mudanças no útero.

Few mammals actually get periods every month or even at all but why Understanding what menstruation really is and why it happens could help ease symptoms and treat conditions that stem from the reproductive system.
Humans menstruate, while 984 other mammal species do not. The video explores which animals menstruate, why this process evolved independently four times, and its biological role. It also discusses the relationship…
A menstruation is more than monthly bleeding; it reflects evolutionary battles between mother and fetus. This video explores how biological conflicts shaped human reproduction and the significance of spontaneous…

@Otonnia Acá hay otro que habla de la limpieza de los posibles patógenos que traigan los spermas y la asimilación genética del conflicto embrión/madre. Sería como un mecanismo de sorteo del sistema inmune para aceptar al embrión. (?).https://t.co/jaEV6Ju7ic

Menstruation evolved at least 3 times - primates, bats and the elephant shrew (more closely related to elephants & shrews!), possibly via genetic assimilation, to protect against aggressive embryos & for better embryo selection - interesting read!: https://t.co/dcTDyLCUL9 https://t.co/E88397ztcz
