Environmental scientist Dr Shanna Swan has warned that pollution is causing penises to shrink. In her book, 'Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race', she explores the correlation between smaller penises, lower sperm counts, and the use of industrial chemicals in everyday products. Swan's research found that exposure to phthalates, chemicals commonly found in plastics and toys, during the first trimester of pregnancy led to shorter anogenital distance in male babies, which correlated with penile volume.

What You'll Learn
Phthalates and their impact on penile development
Phthalates are endocrine-disrupting chemicals with anti-androgenic qualities. They are used as plasticizers and in personal care products. Phthalates have been linked to reproductive toxicity, particularly in the male foetus.
Phthalates have been documented to possess anti-androgenic action in experimental models. Rats exposed to phthalates exhibit reduced levels of fetal testosterone, reduced anogenital distance (AGD), and congenital abnormalities of the male internal and external genitalia.
In humans, studies have found shorter anogenital distance, reduced penile size, and altered hormone levels in infant boys whose mothers were exposed to higher levels of some phthalates during pregnancy. A study by Swan et al. linked phthalates to physical changes in young boys, including smaller penis size and testicles that hadn't fully descended. Another study found an inverse association between prenatal phthalate exposure and penile width and length in newborns.
However, some studies have failed to find significant associations between phthalate exposure and penile measurements. A Canadian study found no strong evidence to suggest an association between maternal first-trimester urinary phthalates and penile length or width in term singletons. Similarly, a study in New York found no clinically meaningful associations between early pregnancy phthalate exposure and fetal penile length or width.
Overall, while there is some evidence to suggest that phthalates can impact penile development, the research is mixed, and further studies are needed to clarify the relationship.

The link between BPA and sexual problems
Bisphenol-A (BPA) is a chemical that mimics estrogen in the body. It is a major component in hard plastics, like polycarbonate plastics and epoxy resins, and is also found in canned food linings and baby bottles. BPA is directly linked to short-term and long-term sexual dysfunction in men.
A study of 634 male workers across four factories in China found that men exposed to BPA were four times more likely to suffer from erectile dysfunction, reduced sexual desire, and diminished sexual satisfaction. They were also seven times more likely to have difficulty with ejaculation, even without erectile dysfunction. These effects were observed after just a few months of exposure, not years.
BPA functions as a synthetic form of estrogen in the body. When you consume BPA, your body's estrogen receptors are activated, tricking the body into thinking it has more estrogen than it actually does. This excess estrogen causes the body to stop producing testosterone, creating a dangerous hormonal imbalance. This imbalance can lead to low testosterone, low libido, erectile dysfunction, behavioural changes, anxiety, stress, weight gain, muscle loss, and even the development of male breasts.
BPA has also been linked to a variety of other negative health effects, including infertility, early-onset puberty, diabetes, and cancer. Despite this, the Food and Drug Administration (FDA) maintains that BPA is safe for human consumption at certain levels. However, nearly 100 academic studies have disputed this claim, highlighting the potential dangers of BPA exposure.
To minimise exposure to BPA, individuals can take several steps:
- Choose organic, whole foods: Reduce consumption of canned and plastic-packaged foods, as these often contain BPA. Canned foods are also high in sodium, which can lower testosterone and sex drive.
- Look for "BPA-free" labels: While the FDA does not regulate the use of the "BPA-free" label, many companies are moving away from using BPA to protect their customers.
- Store food in glass or ceramic containers: Avoid storing food in plastic containers, as BPA can seep into the food.
- Avoid heating plastic: Do not put plastic containers in the microwave, cook with plastic, or leave plastic in the sun for extended periods. Heating plastic releases chemicals, including BPA, which can then transfer to food.
- Detox your body: Detoxification helps eliminate chemicals, pollutants, and toxins from the body. Intermittent fasting and consuming raw, organic foods are recommended methods to detoxify the body.

How pollution affects fertility
Environmental scientist Dr. Shanna H. Swan has warned that pollution is causing penises to shrink and is impacting fertility rates. In her book, "Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race", Dr. Swan discusses the correlation between smaller penises, lower sperm counts, and the use of industrial chemicals in everyday products.
Dr. Swan's research found that exposure to phthalates, chemicals commonly found in plastics and toys, during the first trimester of pregnancy, led to shorter anogenital distance (AGD) in male babies. Phthalates are known to lower testosterone levels, and exposure to them in the womb has been linked to smaller penis size and testicles that have not fully descended. This is known as "phthalate syndrome", which was first observed in rats.
The impact of pollution on fertility is not limited to penis size. Research has also shown that exposure to pollutants can reduce semen quality in terms of volume, sperm concentration, and total sperm count, all of which can lead to infertility in males. A 2022 study also noted that bisphenol-A (BPA), another chemical compound, is associated with decreased sperm production and sperm vitality.
The effects of pollution on fertility are not just limited to males. A Danish study found that exposure to dangerous "forever chemicals" during early pregnancy could result in male children having lower sperm counts and quality later in life. These "forever chemicals", also known as PFAS, do not break down in the environment or the human body and can accumulate, causing increasing damage over time.
Dr. Swan's research highlights the urgent need to address the impact of pollution on fertility. She recommends reducing exposure to hormone-altering chemicals, such as phthalates and BPA, by choosing glass, ceramic, or metal food storage containers and bottles instead of plastic. She also emphasizes the importance of limiting the use of endocrine-disrupting chemicals in everyday products and advocating for stronger policies to protect the health of children, men, and women.

The role of endocrine disruptors in penis size
Endocrine-disrupting chemicals (EDCs) are believed to play a significant role in penis size, particularly in causing penis shrinkage. These chemicals are known to interfere with the body's natural hormone production, leading to a range of reproductive issues. The most commonly discussed EDCs are phthalates, which are used in the manufacturing of plastics and a wide range of consumer products.
Phthalates have been linked to reduced penis size, with studies showing that exposure to these chemicals in the womb results in a shorter anogenital distance (AGD) in male infants, which is correlated with penile volume. This phenomenon has been termed "phthalate syndrome". The transmission of phthalates to infants can occur through toys and food, with pregnant women who have higher body concentrations of phthalates giving birth to boys with smaller penis sizes.
Bisphenol-A (BPA), another EDC, has also been implicated in reproductive issues. Studies have found that higher levels of BPA in the blood are associated with sexual problems, including decreased desire, in both men and women. Other EDCs, such as parabens and atrazine, found in plastics, herbicides, toothpaste, and beauty products, are also believed to contribute to decreasing libido and fertility.
The impact of EDCs on penis size and reproductive health is a growing concern, with some researchers warning of a potential "existential crisis" in fertility rates. While more research is needed to fully understand the complex interactions between these chemicals and human biology, the current evidence suggests that EDCs are indeed playing a role in altering penis size and reproductive health.
To mitigate the impact of EDCs on penis size and fertility, experts recommend reducing exposure to these chemicals. This can be achieved by limiting the use of plastic products, especially for food storage, and opting for phthalate-free and BPA-free alternatives. Additionally, buying organic produce, reducing plastic use, and eating home-cooked meals can help lower the risk of exposure to these harmful chemicals.

Chemicals in plastics and genital defects
There is a growing body of evidence that suggests a link between genital defects and chemicals found in plastics. These chemicals are known as endocrine-disrupting chemicals (EDCs) and they can interfere with the body's hormones, such as estrogen and testosterone. EDCs are found in a wide range of products, from plastics to personal care products, and have been linked to adverse health outcomes, particularly in fetal development.
The impact of EDCs on genital development
One particular EDC, diethylhexyl phthalate (DEHP), has been the subject of several studies. DEHP is commonly found in plastics, foods, and personal care products. Exposure to DEHP during pregnancy has been linked to abnormalities in newborn boys' reproductive organs, specifically an increased likelihood of hydrocele, a condition where fluid builds up in the scrotum. This finding has significant implications as it provides direct evidence that exposure to EDCs can result in changes to the reproductive system.
The role of phthalates in genital defects
Phthalates, a type of EDC, have been identified as a potential cause of genital defects. Studies have shown that higher concentrations of phthalates in pregnant women are associated with an increased risk of their newborn boys developing genital anomalies. Specifically, boys born to mothers with higher phthalate levels had a shorter anogenital distance (AGD), a marker of lower exposure to male sex hormones in utero. This shortened AGD has also been linked to lower sperm counts in men.
Bisphenol-A (BPA) and its effects on fertility
Bisphenol-A (BPA), another EDC, has been linked to decreased sperm production and reduced sperm vitality. Exposure to BPA during early pregnancy has been associated with lower sperm counts and quality in male children later in life. Additionally, studies have suggested a relationship between women's BPA levels and their sexual satisfaction, with higher BPA levels linked to decreased desire.
Reducing exposure to EDCs
Given the potential harm caused by EDCs, it is important for individuals, especially pregnant women, to take steps to reduce their exposure. This can include avoiding plastic food storage containers and bottles, opting for low-fat dairy products, choosing fresh or frozen fruits over canned or processed foods, and minimizing the use of personal care products with unclear ingredients.
While more research is needed to fully understand the impact of EDCs on genital defects, the current evidence suggests that these chemicals can interfere with hormonal balance and have detrimental effects on reproductive health.

Frequently asked questions
Yes, in her book, "Count Down: How Our Modern World Is Threatening Sperm Counts, Altering Male and Female Reproductive Development, and Imperiling the Future of the Human Race", Dr. Shanna H. Swan, an environmental and reproductive epidemiologist, links the use of industrial chemicals in everyday products to smaller penises, lower sperm counts, and erectile dysfunction.
Dr. Swan's research found that exposure to phthalates, chemicals commonly found in plastics and toys, at the end of the first trimester in the womb, led to a shorter anogenital distance (AGD) in male babies. Phthalates are transmitted into toys and foods and subsequently harm human development. Phthalates mimic the hormone oestrogen and thus disrupt the natural production of hormones in the human body, which researchers have linked to interference in sexual development in infants.
In addition to the potential impact on penis size, exposure to pollutants and chemicals has been linked to decreased semen quality, lower sperm counts, erectile dysfunction, and decreased libido in both men and women.
