Menstruation
The Second SexMenstruation is treated as a bodily process with substantial physical effects and as a formative social experience through which a girl may encounter the meanings attached to being female. The account describes the cycle in physiological detail, but rejects the idea that biology fixes women’s destiny: the body is lived within social customs and values, and the shame surrounding menstruation reflects a hierarchy that marks femininity as inferior. Puberty therefore brings more than a bodily change. It makes a socially prescribed future feel immediate, while the recurring cycle can turn that future into a source of anxiety, concealment, and constraint.
The Cycle and Its Physical Effects
The account describes the menstrual cycle as a sequence of changes involving the ovaries and uterus. During roughly the first fourteen days, a follicle containing an egg grows and matures as the ovary secretes folliculin. Ovulation occurs around the fourteenth day: the follicle breaks down, the egg enters the fallopian tubes, and the opening develops into the corpus luteum. In the ensuing phase, progesterone acts on the uterus, whose lining thickens and forms a structure prepared to receive a fertilized egg.
If fertilization does not occur, the uterine lining is not reabsorbed. Its breakdown opens the capillaries, and menstrual bleeding follows; a new follicular phase begins as the corpus luteum is reconstituted. The process is described as involving the wider body as well as the reproductive organs: hormonal activity affects the thyroid and pituitary glands, the nervous system, and other organs. The account reports that more than 85 percent of women show signs of distress during menstruation, including changes in blood pressure, pulse, temperature, digestion, and mood, as well as pain and other complaints. These details establish menstruation not as an isolated event but as a recurring bodily condition with effects that may be felt across the body.
That physical account is framed by a broader argument about reproduction. From puberty to menopause, the woman is described as the site of a reproductive process that does not necessarily serve her individual interests. The monthly preparation of the uterus is presented as a bodily cycle without an individual purpose when no pregnancy occurs. The account calls attention to the resulting sense of alienation: the body is one’s own, yet its recurring processes can seem to follow an impersonal life of their own. This analysis treats that estrangement as an interpretation of lived experience, not as proof that menstruation fixes a woman’s fate.
Puberty, Knowledge, and Shame
Menstruation often marks a girl’s first clear encounter with the bodily reality of puberty. Before her first period, she may anticipate developing breasts with pride, without understanding what maturation will mean. The first bleeding can abruptly alter that expectation. The account describes girls who receive no warning and fear that stains signal illness, injury, or punishment. It cites a survey from 1896 in which, among 125 American high-school students, 36 knew nothing about menstruation when it began and 39 had only vague ideas. It further notes that, according to Helene Deutsch, the situation had changed little by 1946.
The consequences of inadequate information could be severe. One young girl, believing that she had an unknown disease, threw herself into the Seine at Saint-Ouen. Another account, told by Wilhelm Stekel, concerns a child who interpreted menstrual bleeding as evidence of moral impurity and attempted suicide. These examples show how a bodily event could become terrifying when it arrived without explanation and was already surrounded by secrecy and shame. The point is not that every girl responds in the same way, but that silence can leave ordinary bodily change open to frightening interpretations.
A passage from Colette Audry’s In the Eyes of Memory presents the first period as a turning point in a girl’s sense of time. On the first occasion, the girl thinks she is ill and hopes the problem will disappear. When it returns four weeks later, her mother explains what is happening, but the girl reacts with anger and distress; her younger sister’s entrance intensifies her embarrassment. She recalls earlier hints—the doctor’s observation that she is growing up and her mother’s mention of towels for her future use—without having understood them. Afterward, she imagines that the experience will not recur, then has to accept it a month later. The memory divides her life into a before and an after: menstruation has made adulthood seem irreversible before she has had the chance to welcome it.
The same pattern appears in accounts beyond the family home. A motherless girl living with her father and a teacher reportedly hid stained underwear for three months, afraid and ashamed until her menstruation was discovered. A young farm woman washed her underwear secretly in a frozen stream and put it back on wet to conceal what she regarded as an unspeakable secret. The circumstances differ, but both examples connect menstrual shame with concealment and with the absence of a safe, acknowledged way to manage the experience.
Recurrence and the Work of Concealment
The first shock does not end the difficulty. The account emphasizes the repeated practical demands that follow: girls must monitor clothing and bedding, change protection, and manage used sanitary materials. In thrifty households, washable pads are laundered alongside other household linens; commercial products may be discarded, but travel or time away from home can make disposal difficult. The recurring need to anticipate stains and manage supplies gives the cycle a daily and social dimension, extending beyond the bleeding itself.
Uncertainty about when bleeding will begin can add a persistent worry. Young girls may have irregular periods and be caught away from home, while the possibility of a visible stain can make ordinary activities feel risky. The account describes a young patient who would not undress in front of her sister except in darkness during her period, and presents fear of exposure as one source of severe distress. Menstruation thus becomes something to track and hide, not simply a bodily event that passes without consequences.
The contrast between private experience and public knowledge also contributes to humiliation. The girl may wish to keep the experience secret, yet learn that fathers, brothers, cousins, and other men know about it and may joke. What she experiences as a deeply personal change is therefore neither fully private nor treated with reliable care. The account associates this exposure, together with the recurring practical burden, with heightened shame and vigilance.
Social Meaning and the Gendered Future
The account distinguishes the bodily event from the social meanings attached to it. Boys also encounter awkward changes at puberty, but their development is described as being interpreted through virility and entry into adult male status. Menstruation, by contrast, is presented as a sign of femininity in a culture where femininity is associated with alterity and inferiority. The difference in meaning does not arise from bleeding alone: the same physical process could be approached differently in a sexually egalitarian society, where it would signify a distinct way of entering adult life rather than evidence of a damaged or lesser status.
The girl’s response can consequently be mixed. If she has already accepted the condition society assigns her, she may welcome her first period as evidence that she has become an adult. If she has resisted that condition, the same event may feel like a verdict that has suddenly become part of her body. Many, the account suggests, hesitate between these responses, experiencing both the prospect of adulthood and the fear that womanhood brings restrictions. Menstruation is made to carry the weight of a social destiny that had previously seemed abstract.
A clinical example illustrates how that anticipation can become disabling. Molly, described as fourteen and one of five children, was a gifted tap dancer who was shy and troubled by family conflict. She had become preoccupied with childbirth after her sister’s difficult delivery and had heard that women sometimes died in childbirth. When she began menstruating, she felt embarrassed, tried to hide it, and feared that she could now become pregnant. Her anxiety grew into an inability to attend school or lead an ordinary life: she sometimes remained in bed, fainted when required to leave home, and feared pregnancy and death in childbirth. The case links menstrual distress not only to the cycle itself but to the fears and social expectations that the girl associates with it.
Biology, Social Conditions, and Agency
Menstruation is one of the biological facts that shape women’s situation, but the account refuses to treat it as a fixed destiny. It argues that bodily facts acquire social meaning through customs and values; biology alone cannot explain why woman is made the Other. The body has a lived reality through consciousness and action within society, so the question is not merely what happens physiologically but what people make of that fact and the position assigned to those who experience it.
This distinction also limits how the account uses medical and psychological material. Its reports of physical symptoms, distress, and psychiatric cases document how menstruation was described and interpreted in the text; they do not establish that every woman experiences the same symptoms or that menstrual distress is inevitable. The wider argument is about how a recurring bodily process can be taken up as shame, fear, or evidence of inferiority when women’s autonomy is already restricted.
The account’s existential framework makes freedom, rather than an externally imposed idea of happiness, the measure of women’s possibilities. A person’s existence is realized through projects and the continual movement toward an open future; oppression occurs when that movement is restricted and a person is held to a fixed, inessential role. Menstruation is therefore significant not because it determines what women can become, but because its biological reality can be used to naturalize a social constraint. The analysis separates the cycle from that constraint and insists that bodily difference must be understood in its social setting, without turning it into a sentence on women’s lives.
