According to a recent hypthesis, menstruation evolved to protect the uterus oviducts from sperm-borne pathogens by dislodging infected endometrial tissue and delivering immune cells to the uterine cavity. This hypothesis predicts the following: (1) uterine pathogens should be more prevalent before menses than after menses, (2) in the life histories of females, the timing of menstruation should track pathogen burden, and (3) in primates, the copiousness of menstruation should increase with the… 
Menstruation: A Nonadaptive Consequence of Uterine Evolution
  • C. Finn

TLDR
Menstruation is a necessary consequence of these evolutionary changes, and needed no adaptive value in order to evolve.
Menstruation: A Nonadaptive Consequence of Uterine Evolution
TLDR
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 is to save energy by getting rid of tissue, rather than maintaining it in the absence of an available blastocyst.

Induction of Overt Menstruation in Intact Mice
TLDR
Human menstruation can be mimicked in terms of extravaginally visible bleeding, tissue remodeling, and gene regulation in naturally non-menstruating species such as intact female mice without the need for an exogenous hormone supply.
A review on haematological profile in menstruating, pre-menopausal and menopausal women
TLDR
The paper reviewed haematological profile menstruating women,premenopause women and menopause and found that platelets constitute the first haemostatic component that mobilizes in order to interrupt the bleeding as vascular injury occurs.
Characteristics of the endometrium in menstruating species: lessons learned from the animal kingdom†
TLDR
What is currently known about menstruating animal species with special emphasis on non-primate species: length of their menstrual cycle, ovulation, implantation, placentation, decidualization, and endometrial characteristics is summarized.
A missing piece: the spiny mouse and the puzzle of menstruating species.
TLDR
It is proposed that a ≥3-fold increase in progesterone during the luteal phase of the reproductive cycle is a unique characteristic linking menstruating species and why spontaneous decidualisation, and thus menstruation, evolved in these species.
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.
Reproductive ecology and the endometrium: physiology, variation, and new directions.

TLDR
This review will describe endometrial physiology, methods of measurement, variation, and some of the ecological variables that likely produce variation and pregnancy losses and describe the potential of this work not just in reproductive ecology, but in the resolution of broader women's health issues.

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.

TLDR
The use of oral contraceptives reduces the glucose metabolism from endogenous and from exogenous substrates in the endometrium, despite increasing synthesis of glycogen during the cycle.
Elephantulus going into anoestrus; menstruation and abortion
Elephantulus myurus jamesoni comes into oestrus at the end of July or beginning of August. For most animals the breeding season ends in January. Some animals may go into anoestrus in December, others

TLDR
The anti-cuckoldry hypothesis provides helpful insight into the menstrual taboos of the Dogon and should be tested among other populations.

TLDR
The results indicated that there was no correlation between the hormonal status and the growth of bacteria, and any cyclic change in the microbial flora could help in reducing postoperative infections.
Lactic dehydrogenase in the rat uterus during progestation, its relation to intrauterine oxygen tension and the regulation of glycolysis.
TLDR
The present experiments indicate that the level of oxygen to which uterine tissue is exposed may affect the subunit distribution of lactic dehydrogenase and thus may regulate the rate of metabolism of pyruvate to lactic acid in vivo.

Endometrial bacteria in asymptomatic, nonpregnant women.
TLDR
Although contamination by cervical bacteria was possible, there was evidence of separate endometrial flora and type of contraception and phase of the menstrual cycle had no significant effect on the bacterial species recovered.
