WHO’s fact sheet on infertility describes female causes including ovulatory disorders, tubal damage, endometriosis, uterine disorders, and age-related factors. It does not list cold exposure or sitting on cold surfaces among the recognized causes or risk factors. The omission of cold surfaces from a comprehensive global overview of infertility causes indicates that such factors are not supported by current epidemiological evidence.

Cold is a significant environmental stress factor. Studies have shown that exposure to cold environments can cause local or whole-body temperatures to decrease, posing a severe threat to overall health.[1–3] Cold exposure has adverse effects on the female reproductive system [4–6], affecting ovarian [7] and uterine [4] functions and hormone secretion [8]. Therefore, we believe that cold exposure causes abnormal follicular development, damages ovarian function, and induces POAT browning.

Mayo Clinic describes ovarian cysts as "fluid-filled sacs or pockets in an ovary or on its surface" and explains that "Most ovarian cysts develop as a result of your menstrual cycle (functional cysts)." It lists risk factors such as hormonal problems, pregnancy, pelvic infections, and a previous history of cysts. There is no mention of cold exposure or sitting on cold surfaces as a cause or risk factor for ovarian cysts, which suggests that such beliefs are not part of evidence-based etiological factors recognized by major medical centers.

ACOG’s patient FAQ defines infertility and lists causes including "problems with ovulation," "structural problems" of the reproductive tract, age-related decline, lifestyle factors like smoking and obesity, and conditions such as endometriosis and polycystic ovary syndrome. The document does not cite cold exposure, sitting on cold surfaces, or environmental temperature as a cause of infertility. This omission in a comprehensive professional overview indicates that mainstream gynecologic guidelines do not recognize sitting on a cold floor as an established cause of ovarian infertility.

This 2024 mouse study concludes that "cold environment exposure may induce inflammatory responses in the uterus and ovaries, contributing to the formation of an inflammatory microenvironment in the reproductive system." It states that "cold stimulation disrupts the estrous cycle and impairs ovarian structure and function," including a "decline in follicle numbers" and changes in granulosa and theca cell layers. The authors write: "cold exposure induces inflammation of the reproductive system, leading to ovarian and uterine damage, which may further impair female reproductive function" and suggest that such reproductive inflammation could contribute to disorders like polycystic ovary syndrome and endometriosis. This again refers to whole‑body cold environment exposure in animals, not brief peripheral cooling such as sitting on a cold surface.

CDC’s reproductive health resources outline key issues affecting women’s reproductive health, such as sexually transmitted infections, chronic diseases, environmental exposures like certain chemicals, and lifestyle factors such as smoking and obesity. There is no mention of sitting on cold floors or brief cold exposure as a cause of ovarian disease or infertility. CDC’s focus on documented risk factors suggests that the cold-floor belief is not part of evidence‑based reproductive health guidance.

Cold exposure induced estrus cycle irregularity and some alterations in the morphology of the ovary. Cold exposure impairs the function of the ovary probably by changing the level of serum LH and increasing LHR expression. Compared with control group, the cold group showed significant pathological change in the ovary and uterus. In our study, cold exposure caused irregular estrus cycle and ovarian abnormalities.

This 2025 review of experimental and clinical data states: "Cold environment exposure may induce inflammatory responses in the uterus and ovaries, contributing to the formation of an inflammatory microenvironment in the reproductive system. This process may lead to disruptions in sex hormone levels and ultimately impair female reproductive capacity." It summarizes previous rodent studies: "cold stimulation disrupts the estrous cycle and impairs ovarian structure and function" and concludes that cold exposure "induces inflammation of the reproductive system, leading to ovarian and uterine damage, which may further impair female reproductive function." The article discusses systemic or environmental cold stress, not the specific folk belief about sitting on a cold floor.

According to the abstract, "studies have indicated that exposure to cold may prolong the estrous cycle, disrupt reproductive hormone levels, cause abnormal follicular development and impair fertility." This paper reports that experimental cold exposure "induces ovarian dysfunction through endoplasmic reticulum stress and ferroptosis" in female mice, linking chronic cold stress to structural and functional changes in the ovary. The exposure described is controlled environmental cold stress affecting core temperature and physiology, not localized sitting on a cold floor.

The abstract summarised on Semantic Scholar states that "Cold environment exposure may induce inflammatory responses in the uterus and ovaries, contributing to the formation of an inflammatory microenvironment in the reproductive system." It further notes that this may disrupt sex hormone levels and impair female reproductive capacity, based largely on rodent studies of environmental cold stress. The description does not include human epidemiologic data linking everyday behaviors like sitting on cold floors to specific ovarian diseases.

ACOG explains that most ovarian cysts "develop as a result of the normal menstrual cycle" and that other causes include conditions such as endometriosis and polycystic ovary syndrome. The FAQ lists risk factors and symptoms for ovarian cysts but does not mention cold exposure or sitting on cold surfaces as a cause. This reflects mainstream gynecologic guidance that common ovarian problems are related to hormonal cycles and specific diseases, not brief environmental cold contact.

Mayo Clinic describes endometriosis as a condition where tissue similar to the lining of the uterus grows outside the uterine cavity and notes that the exact cause is unknown but may involve retrograde menstruation, immune system disorders, and genetic factors. Their discussion of risk factors and causes does not include exposure to cold environments or sitting on cold floors. This suggests that major ovarian and pelvic conditions in women are not considered to be caused by brief contact with cold surfaces.

In women, cold does not have a direct impact on fertility, as it does not prevent ovulation or implantation. However, it can influence how we feel. When it's cold, your blood vessels contract to conserve body heat. This reduces blood supply to some areas of the body, including the pelvis. In addition, the body releases hormones such as adrenaline or cortisol, typical of "cold stress" responses. If this state is maintained for a long time, it can disrupt hormonal balance and, in the long term, affect reproductive function.

It is also fair to say that the old wives’ tale that piles are caused by sitting on cold (and often wet) surfaces bears little truth on examination. Looking at everything from lifting heavy loads to coughing, sneezing, eating spicy meals and using wet wipes after a visit to the toilet, none of these, not even sitting on cold surfaces appeared to make any difference to a person’s likelihood of getting piles. While piles are nothing to do with sitting on hot or cold surfaces, or seemingly any other factor investigated in the German study, we can at least say why this particular part of the body is prone to the condition.

Mayo Clinic clinicians address the common myth that sitting on a cold surface causes illness and explain that "there is no evidence that sitting on a cold surface causes urinary tract infections or other internal organ problems." They note that while cold can be uncomfortable and may contribute to muscle tension, it does not directly infect or damage pelvic organs. The piece specifically debunks beliefs around cold surfaces causing gynecologic or urinary disease, indicating that such claims are folklore rather than evidence‑based.

In this expert podcast and article, the author notes that "human data specifically examining cold plunging around ovulation or luteal sufficiency is extremely limited" and that "emerging translational and animal research shows potential for cold exposure to increase inflammatory activity in reproductive tissues, disrupt hormone signaling, impair ovarian function, and lengthen cycles." She adds that this "doesn’t prove harm in humans—but it signals caution for women actively trying to conceive." The discussion frames cold immersion as a possible additional stressor in already stressed individuals, not as a proven cause of ovarian disease, and it does not mention sitting on cold floors as a risk.

A cold uterus is a common condition nowadays and can potentially lead to infertility in women. This condition causes the blood vessels supplying the uterus to constrict, making it difficult for normal uterine functions such as ovulation and fertilization to occur. Over time, this can lead to infertility in women. Sitting on cold or wet surfaces: This can cause the body to absorb cold, leading to a cold uterus.

Hormone specialist Dr. Brighten writes that "there is no solid evidence to support such extreme claims" that cold therapy "offers no benefits for women and may add excessive stress for those who are menstruating," and she emphasizes that cold therapy "should be approached on an individual basis." She notes that increased stress can elevate cortisol and potentially affect progesterone, and that women with conditions like endometriosis or dysmenorrhea "may experience increased menstrual cramps when practicing cold immersion due to the constriction of blood vessels." Regarding fertility, she states that "there isn’t any relevant research on this topic" and only suggests possible indirect benefits via decreased inflammation and stress. No direct causal link between brief cold exposure and ovarian health problems is reported.

Research suggests that lower ambient temperatures and seasonal changes can intensify chronic pelvic pain. One study found that individuals with chronic pelvic pain syndrome report pain symptoms that are three times more intense during winter months compared to milder seasons. Cold temperatures tend to cause muscular stiffening and reduce circulation, a natural reaction to help preserve body heat. Unfortunately, that tightening affects pelvic floor muscles too, which can lead to spasms, increased tension, and discomfort. The article advises to "dress in layers and avoid sitting directly on cold surfaces (benches, metal chairs, cold floors)" to help maintain pelvic and hip warmth.

This medically reviewed article notes that "Mouse studies have suggested that cold water exposure may cause inflammation in the reproductive system or alter menstrual cycles." It further explains that animal data indicate cold water immersion might "provoke inflammatory reactions in the reproductive system or disrupt menstrual cycles," but emphasizes that "there is insufficient human research to definitively state that cold plunges pose risks for women." The discussion focuses on whole-body immersion in icy water and concludes that evidence is limited and not definitive regarding female reproductive risks, which is relevant to evaluating claims that any brief cold exposure like sitting on a cold floor causes ovarian problems.

In a study of thirty-one patients with chronic pelvic pain, the subjects reported that pain intensity increased with cold weather. In fact, according to the study, symptoms increased nearly threefold and it was noticed by all subjects in the study. These results also provide important clues about the source of pelvic pain. Cold weather causes muscles to stiffen and tighten, which then increases pain and symptoms. If the pain were coming from an organ – for example, the bladder or prostate – the weather wouldn’t have an effect, since the body is at a constant internal temperature of 98.6 degrees, regardless of outside temperature.

This fertility-focused blog acknowledges that "to date, we don’t have any studies on the effects of a cold plunge on the menstrual cycle or female sex hormones" and that "unfortunately, we don’t have many studies on cold plunge and fertility." It states that "there's no direct link (yet) between cold plunge and female fertility" and suggests that cold water immersion could indirectly benefit fertility through general health improvements like decreasing inflammation and stress and improving circulation and sleep. The article underscores the absence of direct evidence on cold immersion harming or helping female fertility, and does not mention localized cold, such as sitting on cold floors, causing ovarian disorders.

Human internal organs, including the ovaries and uterus, are maintained at a nearly constant core temperature by thermoregulation, even when the skin or external environment is cold. Brief contact with cold surfaces, such as sitting on a chilly bench or floor while clothed, mainly cools superficial tissues and does not significantly lower deep pelvic organ temperature to levels that would cause structural ovarian damage.

In a "Myth vs Fact" post, a medical professional states: "While this belief is common, there is no scientific evidence that sitting on a cold surface causes infertility." The post emphasises that fertility is influenced by factors such as age, hormone balance, ovulatory function, and underlying gynecological conditions, rather than transient contact with cold seats or floors. This directly addresses the folklore about cold surfaces harming reproductive organs and rejects it on evidence grounds.

Cold feet or sitting on cold surfaces causes the blood supply to uterus and ovaries to constrict and contract thus it can cause discomfort and ... In Hungary, people say you’ll get a UTI—sometimes called “freezing up”—if you sit on cold surfaces, and older women used to warn us that we wouldn’t be able to have children. In many Eastern European nations, this idea is surprisingly widespread. It applies to sitting on cold benches, stones, or cement, and people often claim it will damage a woman's ovaries or womb.

This opinion piece argues a pro‑cold‑exposure position, claiming that "women benefit from cold water immersion" and that "both for conception & pregnancy, cold exposure is associated with better reproductive outcomes." It asserts that "ice baths activate brown fat, repair mitochondria, improve insulin resistance, and can boost fertility by correcting metabolic disorders" and that "cold water immersion is safe and beneficial during pregnancy." These claims are presented without citation to controlled human clinical studies, illustrating that some advocates view deliberate cold exposure as beneficial rather than harmful to female reproductive health. The article does not address the traditional belief that sitting on a cold floor harms the ovaries.
