Although adaptive explanations for menstruation go back at least twenty-five hundred years, in the last decade two new hypotheses have been advanced. The first suggests that menstruation evolved to cleanse the uterus of pathogens introduced by sperm, and the second argues that the function of endometrial regression (with the associated menstruation in humans) is to save energy by getting rid of tissue, rather than maintaining it in the absence of an available blastocyst. Both these suggestions…

The evolution of menstruation: a new model for genetic assimilation: explaining molecular origins of maternal responses to fetal invasiveness.
TLDR
It is argued that decidualization became genetically stabilized in menstruating lineages, allowing females to prepare for pregnancy without any signal from the fetus.
The Spiny Mouse—A Menstruating Rodent to Build a Bridge From Bench to Bedside
TLDR
Current knowledge of spiny mouse menstruation is summarized, with an emphasis on spiral artery formation, inflammation and endocrinology, and a new perspective on cycle variation in menstrual bleeding between individual animals is offered.
Menstrual physiology: implications for endometrial pathology and beyond
TLDR
The study of menstruation, in both normal and abnormal scenarios, is essential for the production of novel, acceptable medical treatments for common gynaecological complaints and collaboration and communication with specialists in other fields could significantly advance the therapeutic potential of this dynamic tissue.
Evolution of menstruation in mammals
TLDR
This essay discusses such evolutionary processes by presenting previous hypotheses and presents a new hypothesis in an attempt to give more insight into the evolution of menstruation in mammals and in humans in particular.
Why do women have a menopause?
TLDR
It appears that the menopause is a non-adaptive consequence of two evolutionary developments, one of which is the entry of all female gametogonia into meiosis before birth, giving a finite store of oocytes in the ovary.
Menstruation: science and society
Uterine leukocytes and decidualization.
  • A. King
  • Medicine, Biology
    Human reproduction update
  • 2000
TLDR
The possibility that uterine leukocytes might influence the critical decision that the mid- to late secretory endometrium must make either to decidualize or to undergo menstruation is explored.
Cyclic decidualization of the human endometrium in reproductive health and failure.
TLDR
The endocrine, paracrine, and autocrine cues that tightly govern this differentiation process are reviewed and how disorders that subvert the programming, initiation, or progression of decidualization compromise reproductive health and predispose for pregnancy failure is discussed.

TLDR
It is proposed that menstruation functions to protect the uterus and oviducts from colonization by pathogens, and other forms of normal uterine bleeding-proestrous, periovulatory, implantation, and postpartum-also have an antipathogen function.
Vascular and cellular changes in the decidualized endometrium of the ovariectomized mouse following cessation of hormone treatment: a possible model for menstruation.
TLDR
It is suggested that the changes in the endometrium resemble those of menstruation and support the suggestion that for menstruation to occur the stroma must be differentiated for implantation.
THE EXPERIMENTAL PRODUCTION OF THE MATERNAL PLACENTA: AND THE FUNCTION OF THE CORPUS LUTEUM
In former work I have shown that it is possible to produce at will any desired number of maternal placentas or deciduomata in the guinea-pig, if we make incisions into the uterus at a certain period
Role of the Corpus Luteum and Progesterone in the Evolution of Vertebrate Viviparity
TLDR
It is suggested that ovarian progesterone (follicular or luteal in origin) has a dual role in the evolution of viviparity: to inhibit myometrial contractions, thus providing a primary condition for egg retention and v Viviparity.

TLDR
In the unmated guinea pig the deciduoma breaks down at the end of the 16-day cycle when corpora lutea regress before the next estrus, which can prevent decidual degeneration.

TLDR
The existing dorsal vertebrae in man are to be regarded as the most conservative section of the spine, and the object of the author is to see what evidence may be found in the development -of the spine and carpus, of the descent of man, along with other Primates, from a common stock.
Morphology of the reproductive tract in a lizard exhibiting incipient viviparity (Sphenomorphus fragilis) and its implications for the evolution of the reptilian placenta
TLDR
The findings suggest that the reduction in shell thickness associated with the evolution of a placenta is due to a decrease in the number of shell glands in the uterus and is not a delay or inhibition of the shelling process per se.
Placentation.
TLDR
The paper reviews ungulate placentation, successes and failures of interspecific embryo transfers, and the scant knowledge of genetic determinants in primate placentas.
