- Nausea and vomiting
- Fluid accumulation
- Long-term hormonal regulation problems
- Ectopic pregnancies
- Insulin sensitivity

- Significant weight gain
- Fatal blood clots
And here are some details about a few of the worst side effects:
Fatal blood clots
One of the most serious negative effects of the Pill is the increased risk of deep vein thrombosis, or blood clots that can potentially become fatal. According to the Guardian (March 6, 2009), Britain’s most prominent left-wing newspaper, some versions of the Pill increase the risk of deep vein thrombosis by five times, as reported by the British Medical Association and the Royal Pharmaceutical Society of Great Britain.
Long-term hormone regulation problems
Among the negative effects of the Pill is difficulty in the woman’s body regulating her testosterone levels even when no longer using the Pill.
In the January 2006 issue of The Journal of Sexual Medicine, researchers reported that abnormally low amounts of unbound testosterone caused by Pill use persist after women cease using it. Women’s bodies use testosterone, as men’s do, to regulate sexual function, though in far lower amounts. Said report author Dr. Irwin Goldstein, “This work is the culmination of 7 years of observational research in which we noted in our practice many women with sexual dysfunction who had used the oral contraceptive but whose sexual and hormonal problems persisted despite stopping the birth control pill.”
The Pill especially increases the risk of breast cancer in women of childbearing age.
When taking hormonal birth control, “teenagers are especially vulnerable to breast cancer risk because their breasts are growing,” reports the Breast Cancer Prevention Institute. The Institute also insists, that although the Pill lowers the risk of ovarian and endometrial cancers, “according to the American Cancer Society, out of [a random selection of] 100 women with cancer, 31 have breast cancer, 6 have endometrial cancer and only 3 have ovarian cancer, so it is not a good ‘trade-off’ in risk.” The World Health Organization (WHO) discussed the Pill–breast cancer link in a 2005 report, as did the New England Journal of Medicine in January 2006. The WHO’s panel of scientists concluded that the Pill indeed raised the risks of breast, cervical, and liver cancer, classifying in as a carcinogen.
Loss in overall “well-being.”
A Kinsey Institute study found that 40 percent of women who started the Pill felt a drop in “well-being,” and 40 percent also felt a loss of sexual desire. That means a significant number of women feel the negative effects of the Pill affect them emotionally.
Elle, the world’s best-selling women’s fashion magazine, reported, “Elizabeth Lee Vliet, MD, a women’s health specialist and the author of It’s My Ovaries, Stupid!, thinks that OCs’ [oral contraceptives’] negative impact on moods—she especially blames high-progesterone formulations—might even bring about the need for antidepressants: The Pill screws up a woman’s mood and libido, and then she ends up on Prozac.”
Choosing the wrong man
A study published in the August 2008 edition of the Proceedings of the Royal Society B found that when women smelled the T-shirts worn by men, they were attracted to more genetically dissimilar men before going on the Pill. After going on it, they were attracted to men genetically similar to themselves.
This means that a woman on the Pill before marriage who later stopped taking it in order to have children could cease being attracted to her husband; as evolutionary psychologist Craig Roberts, one of the researchers, explains, “Not only could [genetic] similarity in couples lead to fertility problems but it could ultimately lead to the breakdown of relationships when women stop using the contraceptive pill, as odor perception plays a significant role in maintaining attraction to partners.” So, the negative effects of the Pill are social, not just physical.
Marriages between genetically similar people are also more likely to produce children with genetic problems.
Poisoning the environment
Much of the female hormone in the Pill is excreted via urine and ends up in the world’s rivers and lakes. Scientists are finding ever-greater numbers of “intersex” animals in aquatic environments that could lead to a collapse in fish and other populations, followed by a collapse in the populations of animals dependent on them. The Washington Post reported on April 22, 2009, “More than 80% of the male small mouth bass in the Potomac River are growing eggs.” The first intersex bass were discovered only in 2003, making the growth of this phenomenon extraordinarily rapid. In certain places, said the Post, “100% of the male fish had some female characteristics.”
In the February 8, 2008 Post, scientists said the cause “is probably some pollutant created by humans—perhaps a farm chemical, or treated sewage, which can contain human hormones or residue from birth-control pills.” The later Post article reported that scientists think the problem is caused by a mixture of hormone and hormone-mimicking pollutants, and have found negative effects on female fish as well. Iain Murray, author of The Really Inconvenient Truths, wrote on National Review Online (April 22, 2008), “By any standard typically used by environmentalists, the pill is a pollutant. It does the same thing, just worse, as other chemicals they call pollution.”
Though the Pill appears to act the great majority of the time in preventing conception by suppressing ovulation and inhibiting sperm transport through the woman’s body, at other times it causes abortion by preventing or disrupting the implantation of an already-conceived child. In some women, the Pill suppresses ovulation completely. When the Pill fails, conception may follow and a subsequent abortion of unborn children may be pursued.
The negative effects of the Pill range from headaches and hair loss to fatal diseases such as cancer and deep-vein thrombosis, even to social problems, environmental problems, and abortion. Contraception harms women.
