Jennifer Gunter is a Canadian-American gynecologist, a New York Times columnist covering women's health, an author, and a specialist in chronic pain medicine and vulvovaginal disorders.

In 1995, Gunter moved to the United States for a fellowship in infectious diseases and women's health at the University of Kansas Medical Center, where she also developed an interest in pain management.

During this time, the loss of one of Gunter's sons in a triplet pregnancy she described as traumatic made her decide to shift her work away from the field of obstetrics.

"It is simply not acceptable to me that quality research that can save lives and reduce suffering could be undone by a medical conspiracy theorist or a celebrity looking to sell supplements.

Gunter stated that she wrote the book to counter what she considers a large amount of dangerous false information on the web about female health.

[27][28] As a doctor, Gunter has spoken out on a variety of topics affecting women's health, including abortion,[13] the HPV vaccine, and the use of fetal tissue in research.

[13][23][29][40] Her criticism of one of Goop's products, a jade egg meant to be inserted in one's vagina, came to the attention of a wider audience when her blog post of January 17, 2017, was picked up by a tabloid newspaper.

[8][29][43] This exchange provoked an intervention by Timothy Caulfield, a Canada research chair in health law and policy at the University of Alberta, who supported Gunter's position.

Caulfield stated that, "studies have consistently found, for example, that celebrities can have a measurable and less-than-ideal impact on everything from cancer screening to smoking to the food that we eat.

"[44] In October 2018, Gunter and archaeologist Sarah Parcak published a study to investigate whether or not jade eggs were used vaginally in ancient China, as Goop's marketing claims they were.

[29][45] In June 2019, the Canadian Broadcasting Corporation announced the 10-part docuseries called Jensplaining, which aired on its free streaming network, CBC Gem, in August 2019.

[46] The series comprised ten episodes, with topics including menstruation, wellness, vaccines, menopause, weight loss, birth and sex.

[13][47][48][49] In February 2021, Vagisil released a new line of products called OMV!, aimed at teenagers, which include scented wipes, cleansers and anti itch creams for vaginas and vulvas.
