Jo's Cervical Cancer Trust, a United Kingdom-based non-profit, is offering alternative vocabulary for women's genitalia to increase what the organization is saying is inclusivity in medical language.

According to the cancer trust's official glossary of LGBT-inclusive terms, "bonus hole" is an optional term for "vagina" in the context of cancer treatment.

According to its website, the trust offers the following definition and guidelines: "An alternative word for the vagina. It is important to check which words someone would prefer to use."

The glossary also offers "front hole" as an alternative term for a vagina.

"Using the correct language when referring to someone’s gender identity is a simple and effective way to demonstrate support and recognition," Jo's Cervical Cancer Trust states in the glossary section of its official website.

"If incorrect language is used without being corrected, it can cause someone to feel hurt or distressed. This may lead them to leave and to eventually seek support elsewhere."

Fox News Digital reached out to Jo's Cervical Cancer Trust for clarification on the term and on what basis the recommendation is made. 

"The information is from a webpage written for health professionals to support trans men and / or non-binary patients with a cervix to attend cervical screening," Jo's Cervical Cancer Trust told Fox News Digital. "The page includes a glossary of terms they may hear from their patients and was developed with expert organisations who work with the LGBT community."

The statement continued, "Our mission at Jo’s is to prevent as many cervical cancers as possible, and a big part of that is increasing uptake of cervical screening. Women are our main audience for this, however some trans men and / or non-binary people have cervixes and to reduce as many cervical cancers as possible we also provide information for this group."

Jo's Cervical Cancer Trust began operation in 2000 after being founded by British businessman James Maxwell. 

The trust was named after Maxwell's wife, Jo, who died of cervical cancer in 1999. 

James Maxwell died in 2003.
